Dont know how much money you have to spend as the sky is the limit in high perf. pre/pros. To recommend pre/pros that will "not compromise sonics" I think is easy. Most of the good ones will better the sonics of the average good system, if not drop your jaw. I looked at a bunch, it came down to two.
I went with the Proceed AVP after countless hours of research and getting a smoking deal on one. Since my priorities were much like yours: music first, then theater, under $3000 used, and upgradeable, to me it best fit. It has very nice quality DACS for two channel playback, and HT is close to good as it gets. The thing is good to go for 7.1 and is upgraded via software. Upgrades in hardware look to be major surgery, if at all. And it has an anolog pass through feature in case you get a CD player or DAC that has better 2 ch. sound than the AVP DACs (lots of the other contenders lack this feature). I am still coming to terms with it but so far it has performed well beyond my expectations. Its up there with the best for 2ch. most things and great but can be bettered for HT. I should have it for some time to come. Well worth the investment. VERY user friendly. Madrigal has real good support (though I would like to see that 24/96 upgrade before I die). It replaced and bettered a pretty nice 2 ch. setup.
The Theta CasaNova is another model that made my short list. Has most of the features of the AVP, no analog pass through, both hardware (cards like a pc) and software upgradable, many think by barely not quite as good as the AVP in 2ch, though some actually prefer, it is on par for HT.
Others that got ruled out early: Classe (not upgradable to my knowledge, and dont like it generally). Aragon (same). Lexicon DC and MC (top notch HT, 2ch. ??? could be missing out, but think not) Meridian (top notch HT, 2ch. like the Lex.--think not, price) Theta CasaBlanca (I wish, price) Integra (not on the used market when I was looking). I am sure there are plenty of others, but this was my list of runners that got ruled out for reasons I cannot even remember now.
All above should do really well for you in any case. Go check out the websites of Proceed and Theta, both these companies are very helpful in listing a bunch of reviews in their favor that do a pretty thorough job on details, pros, cons etc.. I think each discussed will easily meet your criteria.
Hope that helped.
