If you're looking for new equipment, the LFD Mistral integrated amp has gotten nothing but positive feedback from very respected people. Musical Fidelity products also tend to have the characteristics you mention.
If you're looking for used gear, I would echo the McCormack suggestion for several reasons. First, the equipment is well made, sounds great and is available used online at ridiculously low prices.
Second, you wanted a manufacturer with integrity and Steve McCormack is as good as I've found. In my experience, he is very free with his time, knowledgeable, helpful, and always available via email or phone.
Third, his products allow you to easily upgrade for modest prices. He has several levels of revisions for his products. You can also simply upgrade by inexpensively adding another amp to your system and biamping.
Fourth, I don't think I've ever heard of anybody having a mechanical problem with McCormack gear. I'm sure it happens, since we're dealing with electronics, but I just never hear it unlike some other manufacturers.
