Northy, I am a very conservative with my system. My Holo My plays my CDs with my two Bel Canto CD2 and CD3t transports and my computer Apple Pro for high res DSD or PCM files. For video I use as computer's monitor the HDMI 2 input in My Samsung TV. On the HDMI I input, I have my MV-60 Anthem video processor. All my video goes through it. DVD Blu Rays, TV cable, and Apple TV.
On the other hand, I am really enjoying my Holo. Everyday that I listen to the music, is an experience as never before. Sound quality is a matter of liking, and perhaps there are people who prefer other sound quality. Me? I am in heaven. Both HQplayer and Audirvana Studio bring the quality sound of the Holo. I don't like oversampling. The Holo does not like it. It is much clear, without any artifact, the quality sound offered by the Holo. Including 44.1KHz/16bit!!! The unit belongs to another level, much higher than what I supposed it was going to be. I did try the I2S connection. The truth is that the USB works beautiful...I do not need more. My ears are very happy with it...very, very happy. This is the best sound quality that I ever have.
Happy listening!
