I2S Recommendation


Mfr. of my new DAC (LAIV Harmony -- grand theft it is so relatively cheap yet so good!) recommends I2S over RCA, so now I am searching for an I2S to hear if it is a step up from the RCA digicable, which I am happy with. Thoughts? Neal

@lanx0003 The company (Veritas Cables) claims the two cables sound identical although they each have a different cable design of some sort.

"Thus we end up with the Optimus 50 - a 50cm cable (aka .5 meters), and the Optimus 100 - a 100cm version (aka 1 meter). Different looks, different internals, but the same performance and the same price". 

Veritas has surely left the door open for debate on this.  In their own words "...We've never encountered another cable type where length impacts performance to such a large degree. After trying many different ideas and mostly failing to achieve the goal, our solution was to use two completely different cable designs to overcome those differences. Thus we end up with the Optimus 50 - a 50cm cable (aka .5 meters), and the Optimus 100 - a 100cm version (aka 1 meter). Different looks, different internals, but the same performance and the same price."  Hmmm, I bet somebody will hear a difference, but until someone lake v-fi steps-up to test them back-to-back, we won't know.

Everyone says shorter is better, but it would be hard to turn down a longer length for the same money if they indeed sound identical.

I find the claim the two different length cables sound identical to be dubious. I2S clock designed to be placed directly in front of I2S pathway in dac. Using external clock with I2S cable actually adds jitter due to reflections in cable, the longer the cable the more jitter added. Perhaps this wouldn't be heard in a lower resolution setup?

@sns  I agree. I bought the 0.5m DH Labs HDMI 2.1, and if I decide on the Veritas, I’d also consider the 0.5m version. The only drawback is that the DH Labs 0.5m HDMI often needs to be twisted with some force to align properly with the I²S port.  But sound quality outweighs convenience factor.
