I have experience with HDMI in audio between my transport and DAC as a vehicle in I2S format to send Redbook cd and DSD data in between the components. In the past the cable really did matter--and personal taste may dictate which one might be preferred by a user. I have settled on the PS Audio silver HDMI cables, long discontinued, but I bought enough used over the years to outfit all my systems where HDMI is used. My second favorite is the Van Den Hul HDMI cable. In the most recent of the DAC editions the input matters less and less; HDMI, USB, AES/EBU and Toslink all have very similar sound quality. But the quality of cable still seems to matter.

I find it matters for video and audio on DVR, TV and optical players as well. Worth experimenting.

Guys, I appreciate the input. I checked out the DH Labs HDMI 2.1. Between the continuous copper crystal and being silver plated, I have just purchased the 0.5 meter cable.

Useful information.

I've had a few days to listen to the DH Labs HDMI 2.1 and the one word I would use to describe the change from a generic HDMI cable is one of refinement. The first thing I noticed was how refined the highs became. The highs were easy on the ears and extended. The cymbals previously had body when struck but now includes more of the sheen. Little details lost in the mix are now much clearer and lack any noticeable edge. The highs by far surpass the best of any of my previous systems.

The refinement also translated to the other parts of the musical spectrum. Initially the lows were not as loud as before yet low level lows were more easily heard than before. Prior to this change there were moments when bass drums could sound a little boomy. Those moments have gone away as the lows seemed to be close to a perfect balance.

Voices had a more natural body and the soundstage extended deeper and wider than before.

Conceptually it sounds like many of the ones and zeros changed from a slight noise into clearer and more refined detail. Some noise was lost and replaced with body and more detail. The basic character of the sound was the same as before, only more refined and closer to the sound of the real thing. The sound of this HDMI cable is a clear and noticeable upgrade over the generic one. It was well worth the investment.

I'm glad the DH Lab cable worked out for you. My digital front end was going through a lot of changes when I got mine and I can't remember exactly what it did for me. Mostly I remember being glad I bought it and thinking it was money well spent.
