Sound Characteristics
The Audiolund HDMI I2S/IIS/AV Cable Xtreme Series delivers the distinctive sonic character associated with classic Western Electric sound, combining balance, power, refinement, and authoritative bass.
The midrange is rich and engaging, presenting seductive vocals and dimensional, lifelike instruments. High frequencies are transparent, sweet, and refined, delivering detail without sacrificing musicality.
The overall presentation is highly musical, with an exceptional sense of air and space between performers, a quiet background, and a precisely focused soundstage.
About I²S
I²S (Inter-IC Sound) is a serial bus interface used for transmitting digital PCM audio data between integrated circuits.
Unlike interfaces that combine clocking and data transmission, I²S separates the clock and serial data signals. This architecture can simplify signal handling and potentially provide excellent detail and sound quality when properly implemented.
Compared with S/PDIF or AES/EBU (AES3), I²S carries clock and data over separate signals rather than combining them into a single data stream.
An I²S interface typically incorporates several signal lines:
- Bit Clock: Serial Clock (SCK) or Bit Clock (BCLK)
- Word Clock: Word Select (WS) or Left/Right Clock (LRCLK)
- Serial Data: SD, SDATA, SDIN, SDOUT, DACDAT, ADCDAT, etc.
- Master Clock: Typically 256 × LRCLK, depending on the implementation
Important: I²S Pinout Compatibility
There is no universal standard for HDMI-based I²S pin assignments. Different audio equipment manufacturers may use different pin configurations.
For this reason, the I²S pinout configuration of both the source and receiving device must be confirmed before the cable is built.
I²S Pinouts
Please provide the I²S pinouts for both devices and the required cable direction.
There are generally two commonly encountered configurations, referred to here as Definition A and Definition B.
Alternatively, provide the brand and model numbers of your equipment, such as your Streamer, CD Transport, DDC, and DAC, so the appropriate configuration can be determined.
A-Definition vs B-Definition:
HDMI I2S A Definition: Pink Faun, Wyred4Sound, Audiobyte, Wadia, Rockna, SMSL, LKS, Gustard, JAVS, Singxer
HDMI I2S B Definition: Sonore, PS Audio, Mola Mola, M2 Tech, Aune, Holo Audio, Empirical Audio, K&K Audio, Channel Islands Audio, Musica Pristina, Stahl~Tek, Matrix, DiDiT, HiFime, X-Sabre, Soundaware, Audio-gd, Denafrips, Jay’s Audio
Compatibility
For an I²S cable to operate correctly, the I²S source and playback device must use compatible signal configurations. We therefore recommend confirming the pin configuration of your CD player, transport, streamer, DDC, or other digital source, as well as your DAC, before ordering.
When the signal configuration is correctly matched, an Audiolund HDMI I2S cable can deliver its intended level of performance.
Note: Audiolund generally recommends HDMI I²S over RJ45 I²S where compatible HDMI I²S connections are available. If the I²S cable does not function correctly in your system, the cause may be an incompatible I²S pin configuration. Customers may request a full refund if the cable is incompatible with their equipment.
HDMI AV (HDMI 2.0):
For standard audio-video applications, the cable is built according to HDMI 2.0 specifications.
Features include:
- Compatible with HDMI 2.0, HDMI 1.4, and HDMI 1.3 devices
- Supports video resolutions up to 4K
- Full 18Gbps bandwidth in accordance with HDMI 2.0b specifications
Note: This cable does not support 8K resolution, as 8K transmission requires HDMI 2.1 hardware and specifications.
HDMI Plug Orientations:
Please provide the orientation of the HDMI sockets on your equipment when ordering. This enables us to determine the preferred connector orientation so that the cable can be installed with minimal twisting or mechanical stress.
If your equipment is positioned side-by-side or vertically stacked, please provide this information as well.
Example:
Installation Precautions
IMPORTANT: Insert the HDMI connector gently and slowly into the correct HDMI port. Do not force the connector into the socket.
HDMI connectors contain 19 electrical contacts and should be handled carefully during installation and removal.
Due to its substantial conductor, shielding, and damping construction, the Audiolund HDMI I²S cable is relatively thick and heavy compared with conventional HDMI cables.
To minimize mechanical stress on the HDMI connector and equipment socket, we highly recommend using suitable cable support. A cable support, isolation block, or wooden support positioned beneath the connector can help support the cable’s weight and maintain proper alignment.
Cable Run-In
Most Audiolund cables employ multi-core constructions with multiple conductor combinations, and therefore require an extended run-in period before reaching their intended performance.
OCC Silver conductors use relatively thick solid-core wire and typically require a longer run-in period than Duelund tinned copper, which uses multiple parallel thin strands.
General Run-In Guidelines
- Most Audiolund cables: approximately 100–200 hours
- Xtreme Series: approximately 200–400 hours
These figures should be regarded as general guidelines, as actual run-in time may vary depending on the cable design, system, and usage conditions.
I have been “learning” in High End for over 20 years and I have accepted that, with every change one makes, something is gained but also something is lost. If one gains more than one loses, one must be happy… So: I just installed the Audiolund Xtreme Series Delund Cooper I2S cable in my system and, after 100 hours of burning-in, I can confirm that, for the first and only time in all these years, not only did I not lose anything at all but, on the contrary, I gained much more than I expected and dreamed of: Tonal balance, precision, clarity, wonderful timbres, huge sound stage, great depth, sweetness… All of this can be summed up in two words: Effortless musicality. I finally stopped focusing on frequencies and let myself to feel the music. A small cable dedicated to the “difficult” I2S interface brought a big upgrade to my, quite worked, system, and It brought great joy to my speakers and, of course, to me. Thanks Danny Lee!
The cable is incredible! I never would have thought it would make such a big difference.
The last bit of harshness is gone, the bass is fuller and more precise, and the overall sound is so natural that it’s hard to believe. It’s one of the best upgrades I’ve made!
I can fully recommend the Audiolund Xtreme I²S cable!
音质非常符合我的口味，原来用的国产镀银线，高音稍微有点亮，杜兰果真不错，厚润耐听，必须好评！只是要注意此线非常粗壮，不好弯曲，我是加上脚垫，刚刚好！
Danny always answered my queries promptly and satisfactorily. The cable looks sturdy and a bit hard to bend due to its 0.5m length. I have no regret in choosing this brand over the others. Thanks, Danny.
certainly, the i2s is superior to the aes / ebu but all the same, this cable transfigured the CD player
I recently bought the Nuprime CDT10 reader because it has an I2S output port. the cables I tried did not give satisfaction but when I tried the Xreme I2S cable, the player was transformed… I can’t find any faults to note… (40 years of audiophilia)
I tried quite a number of i2s cables and this is the most satisfying. This really brings out the musicality with such glorious mids and pleasant-sounding highs and lows. Service from the seller Danny is also excellent. He is very patient, helpful and never gets tired replying to my messages.
A well built cable that add warmth, bass weight & hi frequency sparkle in my system.
Danny has gone out of his way to ensure an amazing experience…..the cable is out of this world …sound quality at it’s very pinnacle!!
A truly wonderful I2S cable. My system was lacking a little musicality running my previous AVPlay HD300 pure silver I2S cables or red WireWorld Starlight 7. The Audiolund XTreme I2S has this in spades delivering very natural sounding voices. A very worthwhile upgrade.
