Thanks all. So I’m focusing on a good, current or vintage two channel amp. (Used, lower price and I’ll take my chance on repair need.) There are several choices including the great ones you’ve all suggested here. Current focus for this purpose is perhaps Mark Levinson 23, or Bryston 4bst -- or one of the others. Now for the pre-amp question -- quality in! (I now get that.) But before I move off into the two-channel pre-world, like perhaps Casablanca, is there a solution such as this Marantz pre that would not overly color the signal in? (Or perhaps if it leaves the signal unmolested, this lesser version.) Or am I understanding the hard truth that this is going to crap up the system even though it’s not having an amping function?
And even so, tis, you spoke of the full quality two channel (end-to-end) system, with alternative, cheaper HT passthrough. Would that linked system above accomplish that? Or when you talk about pass through, is there a system that allows this to do so far more unmolested?
In all cases, is there any chance that a system such as that can be combined such that (with those features) it can be the "turn-on-and-control-all" system including the quality two-channel system? Or in all cases, am I going to be looking at a tradeoff choice of those features vs. quality? If so, I’m a little puzzled, tis, by what you’re suggesting in terms of integration, as it seemed to imply that there was a solution that would fit what I was looking for. In other words, I'm suspecting that if I ultimately want any HT, I might have to hit multiple on switches for multiple systems to get both quality AND HT. (Although I’m sure I have that pretty muddied up at this point.)
I did go listen to the Denon today, and INSTANTLY dropped it from consideration. Heard a lesser powered Marantz amp (which arguably is the same quality realm) but had nicer sound -- which then led me to the question of the possibility of using Marantz simply as a pre system, hoping to bring me even closer to a full picture, including quality. But again, outside of an expensive pre system, I understand I may not have an option.
In all cases, budget will probably have me piece a system together in steps, starting with two channel music, adding streaming audio and the like, and perhaps TV somehow, down the road.
