prem - it is currently mated with NAD C375. I am liking it with its own pre and NAD CDP C542
I tried with lyrita pre, but I am liking the nad integrated better. I think the character of speakers has changed slightly - from very bright in my room to decently laid back, with details. Will try lyrita back.
My observation about loose bass with NAD was incorrect, as I did some listening yesterday. I recalled that I was using appletv to play, and its analog outs

I did not find any looseness with NAD CDPs analog outs.
I am thinking of buying NAD MDC dac, hoping it to sound very close to what CDP sounds. It doesn't have coax input, but it is fine for me, as I will then use my appletv as music media player, that has local hard disk attached, and sends out bit-perfect digital out on optical.
I think I will never use a USB from a computer. Even if I ever use a music PC, I will use a sound card.
