Recommendation for an HDMI cable under $200 for audio only

I’d second the DH Labs HDMI 2.1, but this one from Wyred 4 Sound also looks interesting and worth a look.  The key is to keep it as short as possible because i2S degrades quickly with distance.

If you want a cheap cable for comparison purposes I use this one from Monoprice with great results, and a 1 foot length is only 8 bucks.  Best of luck.

Anything will work due to the data being 1's and 0's which will transfer the same regardless of the cable or what the people who erroneously believe they can hear a difference will tell you. 

I will be a bit of a contrarian here; my recent experience with DH Labs' SilverSonic HDMI 2.1 (and their power cables as well) has been comparatively underwhelming.  I've been running blind preference tests between it and a few other HDMI cables, and every listener who has opined on it has ranked it either last or second to last in their preference. Their critiques mention squashed soundstage, harsh & flat treble, and notably recessed mids on my KEF Reference/Parasound Halo stack. My listeners' most consistent picks in your price point have been the AudioQuest Cinnamon.

Audio quest  has very good HDMi cables at different price points.

in my set up with PSaudio transport and Dac I have found Dragon HDMI is the best cable to my liking.
