I2S Recommendation

I wired my theater system with Pixelgen cables and it made a noticeable difference in the display, although I didn't notice much in the way of audio improvement.

Audioquest Vodka 48 8k/10k work exceedingly well for i2S (though are expensive), I found mine on sale for around $350.....but I needed a little longer cable, so spent the extra cash. Supra Cables .5 meter are excellent at around $65, if you can use that short of a cable

And the (interim) winner is: DH Labs 2.1, .75 length. Will burn it in a for a few weeks and see if it beats my LessLoss RCA digicable. If the I2S is a big winner, I may move up the ladder. (Does it ever stop?) Neal

Congrats.  Be interested to hear what you find. 

@nglazer May I ask what Streamer you are using with your Harmony?
