I2s vs spdif AES/EBU . the CS8406 TXP pin is the digital audio output which uses the SPDIF protocol, yet it goes to a transistor which drives a speaker as if it were analog audio. Additionally, we will fix the data word size to 16 bits. Every DAC is different, and every system is different. デジタル同軸デジタル】どちらが音が良い？」 Since S/PDIF will typically be converted to I2S before the digital data is passed on to the DAC chip, one might legitimately ask oneself why even bother converting from USB to S/PDIF at all, especially when USB can be AES vs SPDIF is just a different voltage level and AES-3 is compatible electrically with SPDIF. If it does, converting USB (1. When used as an external connector, I2S, apart from allowing for higher bit rates, is about the same as S/PDIF, requires more electrical conversions than USB, brings jitter back into the picture, and creates all kinds of interoperability problems because oh, right, because it is not a proper inter-device connection, and nobody is going to Depends on your needs and your gear. SPDIF jitter performance on a DAC that supports both with a high-quality external I2S source. 5m in length, whether HDMI or RJ45. What is the most straight forward way to convert HDMI ARC port on SMART TV to Digital audio (I2S or SPDIF)? \\n The volume of the digital audio needs to be controlled by the TV remote. • The position of the slots with respect to the frame edges can be selected. I2S. So, there's no easy answer to this question. It is designed to improve the quality of digital Sin sonido o con mala calidad de sonido: Verifique las conexiones de sus cables, los niveles de señal y la configuración de compatibilidad. Some receiver ICs have high jitter (CS841x series are 200ps or greater), some doesn't (AK411x, DIR9001, WM8805 are about 50ps or less). Most of AES/EBU used in consumer audio is S/Pdif standard. Stock 2010 Macbook-USB-North Star USB/I2S converter-North Star 192 MKII DAC. I don’t think it will stop discussions / debates on which sounds better since as they basically say “I2S is better than AES3, is better than S/PDIF” but it depends on the cable and implementation. B. . In any case, FWIW, MSB classifies the various digital interfaces in descending order from best to worst: their implementation of i2S, AES/EBU balanced, S/PDIF on BNC, S/PDIF on RCA, Toslink. Consulte la configuración This is currently what I've done. hiFace Evo の内部：SPDIF系の出力にはすべて絶縁処理がされ、I2Sの出力はLVTH125で駆動されているのがわかる。SPDIF信号については、下記に良い解説が有りました。 RATOC社の解説I2S信号についてはD／Aコンバーターチップの資料を見るのが早いと思います。SPDIF信号は、本来別々に送るべきデータ信号 %PDF-1. In an I2S-Like protocol, each edge of the frame synchronization (FS) is used to align the slot positions. The sound is spectacular. From what I recall, it was PS Audio that popularized I²S for external DAC connections. spdif是sony、philips数字音频接口的简称。就传输方式而言，spdif分为输出（spdif out）和输入（spdif in）两种。 What digital interface is the best? This is a question that is often posted on this channel. If it offers both, there may be differences in the way it handles SPDIF versus I2S, and then it may or may not make sense to use USB->I2S. While the S/PDIF output of the IRIS exhibited all of the improvements noted below, the I2S connection amplified those improvements on the Pontus II. 3v compliant actually means mentioned in manual? - What would be suggested way to toggle between different sources (i2s vs. This article will focus on the differences, advantages, and disadvantages of the inter-IC—rather than inter-board— digital audio formats. I would only use I2s if it is a native output to input, otherwise USB or AES would probably be better. S/PDIF vs. desktop pc-firewire-RME ff400-S/PDIF-North Star 192 MKII DAC vs. In dual mono mode SPDIX TX takes in two stereo (in ADC AK5572 dual mono mode both channels have identical data) streams and picks one channel from stream 1 我们常被悦耳的音乐所打动，偶尔也会思考：这些美妙音频是如何传输的？实际上，音频是通过一系列复杂而精细的步骤传输的：声音采集与存储→音频信号处理→音频输出与感知。最终的声音再现离不开数字音频接口协议。数字音频接口协议是指在数字音频系统中用于传输音频数据的标准化规定 S/PDIF vs. Thanks to its selector, it is possible to change the direction of the transmission. De ce format a été extrapolée une façon de transmettre l’audio numérique en sortie d’un lecteur réseau (ou d’un lecteur CD), différente du S/PDIF. I preferred the I2S HDMI with the Pontus II. 2M (DSD256), but does that the higher the この基板は2チャンネルのみですが、電源はしっかりと外部電源化してあって、一応spdif出力も搭載されていますので、後はパルトラを使うか、フィルムコンを使った回路を経由してspdif出力すればokです。 I have a Jays Audio C D transport with options of spdif, aes/ebu and i2s. Not sure where they place USB, as I haven't yet retrofitted MSB's "quad-speed" USB interface for up to DSD 128 and PCM 32/768. I2S operates at 50% duty cycle compared to the same data stream over SPDIF. YMMV ofcourse Regards interface, for the I2S-Like protocols. But for whatever reason, the external USB-to-I2S conversion via the Matrix makes thing sound better – much better by my and many others’ assessments – than running Le format I2S (Inter-IC Sound) a été développé par Philips dès les années 80 afin de standardiser le transport d’un signal audio à l’intérieur des appareils entre composants sur les cartes électroniques. TOSLINK is optical SPDIF. Thus, it is possible to enter in coaxial to exit in I2S and optical, to enter in I2S to exit in coaxial and optical Lets shoot them out ! your time codes are 0:38 AES/EBU, 2:13 i2s via HDMI, 4:03 i2s via HDMI NOS, 9:18 SPDIF NOS The Matrix Audio X-SPDIF 3 is a high-performance USB interface that converts USB digital audio signals to various other digital formats such as SPDIF, AES/EBU, I²S, and Optical. If the transmission (SPDIF, I2S) affects the bits, there is a big electrical problem which has to be fixed, it cant be compensated. IME RJ45 is preferred because of the larger conductor size but I found no benefit in going below 0. Choosing audio components with mismatched digital interfaces needlessly complicates the This is a review and detailed measurements of the Matrix Audio X-SPDIF 2 USB to S/PDIF and I²S (IIS) converter. If you are unfortunate to have RCA connections for your SPDIF, the best results you will get is if you use BNC cables with BNC-to-RCA adapters. Amir tested the SPDIF input of the Matrix X-Sabre Pro MQA which has similar async/sync modes here -> If noise is present in a coax S/PDIF connection, then TOSLINK will obviously be superior, but noise is somewhat rare with a decent quality component and coax S/PDIF cable. Your DAC may not accept SPDIF input, and you may need a I2S input for it (TDA1543, PCM1792, etc). I've created a amanero USB to I2S to feed this. SPDIF/AES/EBU may sound slightly different from one another. This might not be the case if the audio stack (mixer etc. . I can verify that I have a valid i2s signal on these lines (by using a Quantum Data SPDIF generator), but I can't make the i2s to SPDIF part work. 就传输方式而言，spdif分为输出（spdif out）和输入（spdif in）两种。 SPDIF传输载体 就传输载体而言，SPDIF又分为同轴和光纤两种，它们可传输相同的信号，但载体和接口外观不同。 I also asked Tim if there was any significant improvement using I2S vs. SPDIF与I2S的数据格式与编码方式比较 SPDIF使用双相相位编码（BMC），将时钟信号和数据信号混合在一起传输。每个block包含192个frame，每个frame存储两个声道的采样信号。SPDIF支持PCM和RAW格式， We would like to show you a description here but the site won’t allow us. The card also provides an analog input. 7. Signal conversion model can use the hardware setup, and you S/Pdif includes Serial Copy Management System, preventing second-generation copy in some instances. More information and schematics are available at nihtila. Good luck getting one of those. The electronic signals are the same for both, just different physical interface hardware. A number of devices can convert between I2S and SPDIF (or TOSLINK). I2S 是飞利浦定义的数字音频传输标准，用于数字音频数据在系统内器件之间传输。使用三根数据线：SD（数据线）、WS（帧时钟，也称LRCLK）、SCLK（位时钟，也称BCLK）。I2S 分为 i2s-standard mode ，i2s-MSB-Left-justified mode，i2s-MSB-Right-justified mode三种模式。. Output from th AK4118 is I2S to an Ess9018K2M dac. 1. AES/EBU. If you want to use the newest hi-res formats, then both USB and I2S are the answer. For example: in TDM mode the bit rate is 24 x 48KHz x 8 = 9. but since the board has only one I2S input I've disconnected all spdif input to enable the link between amanero USB to I2S. Reactions: jamesd. The other argument was that many source devices had to convert i2s to SPDIF at the output anyway and back to i2s in the DAC. （二）I2S：音频IC间的“内部高速路” I2S（Inter-IC Sound）是一种广泛应用于数字音频传输的串行接口标准。如果说SPDIF是音频设备间的“外交官”，那么I2S就是数字音频IC之间的“内部高速路”，在音频IC间构建起一条畅通无阻的数据通道。 I2S接口展示 No, the Abbey Road studio is the place there those recordings were made, not the point of origin then you are playing the recording (digitally) with USB, AES, SPDIF, I2S or a renderer many years later. If you using spdif, Some Dac might need receiver chip to convert spdif signal to i2s signal before feed the signal to Dac chip. \\n Thanks! 文章浏览阅读2. On the other hand, if you need a more versatile output Introduction. 3 x The module integrates an isolated Coaxial S/PDIF input and an Optical S/PDIF input supporting audio streams up to 192kHz. DIY ACA class A amplifier with linear power supply. s/pdif)? Just power on/off between sources used? Many thanks! Anyways, so there are several digital outputs on its back panel, AES/EBU; I2S(HDMI), Coaxial, USB Audio, hell hahah, I have literally no idea which one is better or which can provide a special feature or something, I mean it does show that the USB Audio supports up to up to PCM 768KHz and DSD 11. High spec. SPDIF TX is an I2S to S/PDIF digital audio converter. My rec is Revelation Audio Labs HDMI style i2s cable. It’s the best all around. - What does this 3. I like the history and simple block diagrams identifying the functions. But, those who implement it, unlike USB, do it competently because its not something that can be outsourced. USB is ideal for an Antipodes server because it is architecturally superior to SPDIF, i2s and AES/EBU, and generates much less noise in the DAC than Ethernet. Full acoustic treatment. consider using something like I2S which includes a separate line for clock as well as data. S/PDIF and I2S are both protocols for transmitting audio, USB is not. Audio can be stereo 2. I²S Vs S/PDIF. ; Distance: Typically longer distances than coaxial S/PDIF and Ethernet AVB are primarily used for data connections from one PCB to another through cabling. This is an analysis of I²S interface to see if it is superior to S/PDIF or USB interconnects for audio DACs. It really depends on the DAC and personal preference. So, which one is better – Optical or Coaxial SPDIF Output? Well, it really depends on your specific needs and preferences. 今回、optical接続は、私の方の基板のミスで接続できませんでしたが、spdifの同軸接続とhdmi-i2s（lvds）の2種類の接続が出来ます。 pcm9211は、spdif入力した信号をi2sへ出力することができ、そこをtas6422 フルデジタルd級アンプへつなげています。 Unless @amirm has anything to add on the operation of this unit I would use sync mode for USB input and async for SPDIF input. It's not so easy to see in the picture, but the i2s signals are wired from the P7 connector (I2S out) to W11 (pin 3 to 6, i2s input). But if the DAC uses an ASRC or something else that removes jitter, that's probably overkill. So I planned to make a new external spdif to Singxer SU-6 Dedicated Source Component Review. That said it would be interesting to somehow compare I2S vs. Perhaps I know too little about I2S, but it seems like a very poor machine to machine interface when compared to SPDIF. But you cannot hear USB vs SPDIF in isolation: you depend not only on the quality of the implementation of the receivers themselves but also on how your DAC manages the digital flows and clocking (as well as power supplies, ground isolation and A comparison of S/PDIF to I2S is just fine, but a comparison to USB doesn't really make much sense. The approach was the same for everyone: higher bandwidth over 192 kHz, less jitter with SPDIF and less jitter/contamination with USB. So, useful information. Everyone seems to forget, that using I2S I2S input; SPDIF TX is always I2S Master; Supports Dual Mono mode with 2x nihtilacom ADC AK5572 AD-converters; Two S/PDIF output connector options: Coax RCA and optical Toslink, or XLR AES/EBU; What's included? Fully tested board comes as in the photo with all components soldered. The GPIO input allows you to retrieve an audio stream up to 768kHz from the Raspberry Pi. I have no idea which Dacs are great via this. S/PDIF# Sony/Philips Digital Interface (S/PDIF) is a type of digital audio interface used in consumer audio equipment to output audio over relatively short distances. If you’re looking for high-quality audio transmission without the risk of interference, Optical SPDIF Output may be the better choice. When interfacing with older DAC, S/PDIF based connections will probably sound the best, as this system is mature for many years already. Meaning it is in theory better than SPDIF which encodes all of this into one stream and has to be "unpacked" at the other end. ) of the OS is used in computer based playback. I understand the DAC will convert the USB (or spdif) to I2S. When it passed again last week, I found it time to explain the d Raspberry Pi Music Player with SPDIF out; DAC . Dec 16, 2021 #5 The Pro-ject CD box RS2T has this interface, been reading some rave reviews from end users in this particular machine. An external I2S/DSD input is also available, supporting PCM streams up to 32bit 768kHz and DSD up to DSD1024. Higher speed protocols such as video SDI further scramble the bit pattern to make it more or less DC free to aid in clock recovery. Cables used: Spdif: Siltech anniversary edition AES/EBU: Audioquest Coffee I2s: Audioquest Mocha The AES/EBU is the best sounding when paired with the Denafrips Terminator, followed by i2s. • The clock data strobe edge can be selected as well. My latest design uses a PLL to generate that from the SCLK, so no ned i2s和spdif的数据格式区别： spdif跟i2s信号一样，是一种传输协议。 i2s协议规定在高电平的时候传输左通道信息,在低电平时候传输右通道信息. I2s is the best way to go because it offers greater resolution and can handle DSD which SPDIF usually cannot. So I have two possibilities to accomplish that: either using 4 I2S or TDM. The CS8406 is controlled by I2C interface, it cannot transfer audio via I2C interface. There are PCIe soundcards which will convert PCIe directly to SPDIF, no USB host or USB interface is needed, Im aware of the downsides of SPDIF carrying clock and data signals together but it is Of course you NEED to use i2s with a PS Audio transport for features. Vacuum Tube Amplifier . Posted September 22, 2022. Yes, I have a RPi connected via I2S and in use daily. The theoretical objection I have with the Singxer is that it is functionally irrelevant. I2S is actually a format to use internally within digital audio equipment. It is on kind loan from member who also sent me the Wyred4Sound DAC-2v2 SE DAC. g. S/PDIF and AES, on the The typical way of connecting PC to DAC is through USB with USB-I2S interface but im wondering if eliminating USB and using SPDIF holds any value. I am assuming that using the I2S inputs should sound better but It is fairly simple to convert from I2S to SPDIF. • The frame length, the duty cycle, and polarity can be adjusted. 216 Mbps. The CS8406 is basically a I2S-to-SPDIF converter, or digital audio interface transmitter. ちなみに、完全な好みの話になってしまいますが、私はサウンドステージが広いi2sで聴くことが多いです。 でも、こうやって聴き比べると面白いですね。 以上、「【i2S vs. And in fact, it is easier to ignore the clock line than it is to try to re-incorporate Signal Type: Same as coaxial S/PDIF, can carry both uncompressed PCM and compressed audio formats. The 而支持spdif in的声卡芯片则相对少一些。sa902x，sa922x都支持spdif in和out，但sa9123，sa9127,sa9302则不支持spdif in 和out。 2、就 物理接口 而言，spdif又分为同轴和光纤两种，其实他们传输的信号是相同的，只不过是接口不同，连线外观也有差异。但光信号传输是今后 If the I2S codec has a microphone or analog input capability, then the I2S bus allows it to send each sample to the host as soon as the sample is ready, and this relieves the codec of any need to buffer blocks of samples together. 304 Mbps. Location: However with my latest DAC, I can no longer hear any difference between S/PDIF, I2S, nor USB. Weirdness pfm Member. 3 %âãÏÓ 1 0 obj >stream endstream endobj 2 0 obj > endobj 3 0 obj > endobj 4 0 obj >/Parent 3 0 R/Contents[30 0 R]/Type/Page/Resources >/Shading >/XObject There are polished solutions for SPDIF clock recovery with minimal resulting jitter, WM8805, etc. Conversely, the DCS Network Bridge has no USB, but favours AES/EBU. It’s an exceptionally sturdy unit with a construction that screams “quality”. Although I don't think using async with USB will really degrade anything, but for SPDIF I think jitter will be lower using async. I have zero idea which streamers are good w this connection. Asegúrese de que su dispositivo y DAC estén configurados con la misma frecuencia de muestreo. There is no difficulty, just use a cookbook approach. Separate power supply (resistance measured just under 7 Ohms). Thread starter Calamaro; Start date 2009-09-12 9:23 pm; Status Not open for further replies. In I2S mode the bit rate is slower once it transmits just two channels : 24 x 48KHz x 2 = 2. 0 only, preferably uncompressed. TarnishedEars, Jan 22, 2025 #15. When that device was made USB and I2S might still be fairly new and not that polished. So why not let the DAC do that rather than a third box. Just like with IEC-60958 (the SPDIF standard), the protocol can easily be expanded so that WS=LOW means the first channel 前回のI2Sは機器内部でのLSI-LSI間のBusのようなものでしたが、S/PDIFは機器と機器の間でAudio信号を伝送するための信号です。 Thanks. 1) to I2S should not provide any benefit at all, over USB to SPDIF. 0: Compatibility: Mac OS, Linux, Windows (XMOS driver needed) Dimensions: 74 x 34. Discussion in 'Audio Hardware' started by Kiko1974, Jan 21, 2025. With the Singxer we have USB (input) and I2S (output). I would like to understand the difference in clock rates between I2S and TDM. If anyone has seen the review I did on the Matrix X-SPDIF 2, they would know exactly how I feel about USB audio interface reclockers. Occasionally I use a Cd player into the AK4118 coax spdif and even more occasionally an android media player via the optical input. If you want to use the second i2s input, the Matrix SPDIF-2 is good enough for me. But which one is "better" is entirely subjective. I have made some designs in the past using CS8406 and AK4118A for that purpose (only one of the IC's in a design). The issue of processing the samples and storing them (if needed) then becomes a problem for the host only. Dedicated listening and mixing room. The X-SPDIF 2 costs In my previous tinkering with I2S output, I used to think that there was no audible difference between SPDIF & I2S but that was probably because of implementation issues. Unboxing the Matrix X-SPDIF 2 is quite a surprising experience. I2S skips the S/PDIF transmitter and S/PDIF receiver. It’s solid, heavy for its size, and photos do not convey just how sturdy this unit is. A couple of examples might include things like SRC4392 and ADAU1452. Unfortunately, it appears that Toslink, SPDIF/Coax and USB all try to consolidate I2S signals into one single block for the sake of making a “single cable”, ie Bit perfect just means the bits in the original audio file/stream arrives to DAC without any modification. This implies a higher jitter bandwidth for I2S; Clock and signal have separated wires in I2S, while SPDIF cleverly encodes it in the signal I think it depends on which inputs the DAC manufacturer puts the most effort into, but I found running i2S from my Iris to my DAC to be notably superior to SPDIF. It looks like you have all the right the gear to try I2S vs SPDIF coax/. com and A good example is SPDIF. No hay señal de salida SPDIF: Asegúrese de que la salida SPDIF de su dispositivo esté habilitada. USB vs. As a legacy connection many sill prefer over USB. The S/PDIF standard The difference between the I2S and the common s/pdif is that the I2S includes the word clock communication, allowing a DAC to sync with a transport, minimizing jitter. , because an external conversion introduces another cable and power supply into the equation. OSLINK vs USB vs ethernet. i2S is there for the same reasons SPDIF and AES/EBU remain. I agree, it should never have been a thing to connect boxes. 2 Hardware Architecture The hardware architecture for an I2S module is very simple as （I2S = Inter-IC Sound = Integrated Interchip Sound = IIS，是飞利浦在1986年定义【1996年修订】的数字音频传输标准，用于数字音频数据在系统内器件之间传输） （至少在常规的RCA规范的SPDIF接口中，它所能支持的最大码率仅仅是192KHz/24bit or DSD128，这种差异性或许在高 Any S/PDIF interface that does not use a true BNC connection is compromised. The Eera cdp that I have my eye on has a Digital In, and it's SPDIF. But in this article, they sent USB and I2s signal from the same device, Gustard or Singxer This digital interface module offers a bidirectional system between SPDIF (coaxial and optical) and I2S. So despite the technical superiority of I2S over SPDIF in digital audio communication, this can only be realised with good implementation. If you just use RCA cables, even the best SPDIF cables will have compromised high frequencies. It takes in I2S serial audio data in either conventional stereo format or specific dual mono format used in ADC AK5572 AD-converter. IME, USB vs i2s vs SPDIF depends on the relative quality of the output and input implementations (and to a lesser extent the cables). The signal is transmitted over either a coaxial cable using RCA or BNC connectors, or a fiber-optic - Would I be able to connect most s/pdif sources directly to S/PDIF RX input? (I would like to avoid using extra boards (digi FP IO) for i2s. Kiko1974 Forum Resident Thread Starter. The xcore implementation of I²S is provided in the interface library lib_i2s. With a good Hdmi i2s cable it’s definitely a step up. I got my hands on the Singxer SU-6 in 2020. 9w次，点赞29次，收藏202次。音频常用协议说明 IIS协议I2S(Inter-IC Sound Bus)是飞利浦公司为数字音频设备之间的音频数据传输而制定的一种总线标准。在飞利浦公司的I2S标准中，既规定了硬件接口规范，也规定了数字音频数据的格式。特点 效率高主要传输音乐先传高位再传低位。 i2sとs/pdif は相互に移行して問題なく使えますが、dsdとs/pdif とを相互に移行するのは非常に面倒なので専用機として割り切る必要があります。 なお、DSD フォーマットであるSACDの新譜は減少傾向にあります。 Why is I2S better than coax? I am currently using a single crystal pure silver coax between my Perfectwave transport and Directstream dac. This product can convert the signal S/PDIF into I2S signal, or convert the signal I2S to S/PDIF signal. With the Pink Faun it is only I2S. “true” I2S format that are also considered a part of the protocol. \\n Any function related to video is not needed. But I2S requires three or four separate signals, so it can't easily be sent off-board. These other formats include right and left justification mode, but here we will only consider the I2S format described above. The ESP32 I2S table is a lot more complex than the basic standard. ; Transmission: Uses optical fiber for transmission, so the signal is carried by light. I'm using Leaf Audio Amanero as usb-to-i2s and ESI-Juli@ for spdif with Weiliang's This is a product that can convert S/PDIF and I2S signal to each other. 2A3 SE Amplifier RPi digital output boards: a case of SPDIF vs I2S Let's state that best SPDIF board is the DigiOne, even if Allo replied my mail in a very cold and short answer and the fact reviews seems to be made by people who get the board as "a gift". Why does Aqua LinQ favour i2s? And just what is the controversy on USB? USB, S/PDIF, AES/EBU? October 21, 2020 20:24 Updated. DIY NOS AD1865 DAC for Raspberry Pi; DIY ring core SPDIF transformer; Discrete R2R DAC (part 1) Discrete R2R DAC (part 2) Discrete R2R DAC (part 3) CS8416 SPDIF to I2S converter; Solid State Amplifier . There might be a challenge here, since there may not be a suitable MCLK available, which these IC's require. michel8166: I’m referring to this, USB vs i2s. SPDIF bad I2S good And that -- I think -- has been the consensus, on forums for over 10 years. TOSLINK vs RCA SPDIF Output. gat474. この信号はSPDIF（Sony Philips Digital Interface）と呼ばれます。1980年代初期、CDが初めて発売されたとき、CDを発明したソニーとフィリップスは、複数の導体を持つケーブルをCDプレーヤーから出したくありません SPDIF, i2s and AES/EBU suffer because the system clock is in the server, not in the DAC where it really should be, and this is typically heard as dirty and less coherent sound. Start praying. If you try all of this you will find you get lots of interest regarding how ethernet performs without a steamer and DDC. Coax Engineers can derive the clock from an I2S signal exactly the same way that they do with S/PDIF. Admittedly, I could have reached this conclusion as the result of several factors including the cables I used and the 数字音频接口协议是指在数字音频系统中用于传输音频数据的标准化规定，是确保声音信号能够被正确传输和处理的关键，常见的数字音频接口协议有SPDIF、I2S、PDM、PCM等。 （一）SPDIF：数字音频的“桥梁 I2S is a weird thing. When equipment is interconnected via I2S, I2S is not a standard for transmitting data, it is a standard for serial transmission much like 24bit Least Significant Bit First, or the opposite 24bit MSB first. Kyhl, Kiko1974, jpelg and 1 other person like this. I am getting a Wireworld Platinum Starlight 7 HDMI cable in a couple of days and I am wondering why the Wireworld will sound better. - When using I2S from a DDC, again the clock is part of the stream, however i2s uses multiple lines, with the master clock being separate entirely from the data and word clock. Member; PCM : I2S up to 32bit 384kHz, SPDID up to 24bit 192kHz DSD : I2S up to DSD256, SPDIF up to DSD64 DoP: Output: I2S SPDIF (requires soldering) Input: USB-B 2. Option 2: Connect a good SPDIF bridge like the Singxer SU-2 or Matrix x-SPDIF 2 via USB, then the dac to the bridge via I2S Option 3: Use a Pi2AES and connect the dac to the I2S output of that, so that in theory you avoid anything to do with USB altogether. I2S is a very basic communication protocol for transmitting audio data from one chip to another but it's also unedited, untouched and completely free from any processing. The aes/eBu is as good as spdif gets bit imo Spdif is a bit dated. From what I’ve read AES/EBU sounds to be close to i2S in performance, but I haven’t compared directly in my system so can’t say. Does SPDIF just take the I2S format and just change into a single connection instead of 5 connections. In theory, performing the USB-to-I2S conversion EXTERNALLY should sound worse, e. AES/EBU and here is what he said: "Personally I’m all about i2s. I2S vs S/PDIF CONNECTION. ivvqb dlvr huaq ifzyz hzjn pgqkddagf wrwmf wzkpqq lgjvm ynrvzb pvxbh ildfp wvuw yrrw foqvd
