I know the Ayre AX 7e I'm selling has pass through and I think their pre's do also. You can always find a good one on AG. If you just go to a few of the well known manufacturer sites they will put it in their info.
I know that many are in love with the Marantz or NAD's of the world and I own both brands and have for years, however not for my 2 channel listening. they just aren't made for the highest quality sound and that's what you said you are after.
I just spent a ton of money on a new 2 channel system and my friends who listen to it feel that it sounds much better than their own multi channel systems and they spent even more than I did. The more things you add to a component the more difficult and expensive it is to implement. I think I said that correctly.
