I am surprised that nobody has mentioned Pass Lab's Aleph series amps yet. You can find several models for under $2k. But these are hard to find on used market and many owners are just holding on to them. I have an Aleph Os, and it is one of the most tube-like sounding amp I've heard. It had been in my second system which was boxed up due to the arrival of my first born two years ago. The system consisted of:
Sonic Frontier SFT-1/Mark Levinson #36/ARC LS-1/Pass Aleph Os/Unity Audio Signature 1s. It was a very musical sounding system. (The amp was not powerful enough to drive my speakers in my main system, otherwise I would have used it) My wife loved my little system more than my main system which is more analytical sounding. I've been contemplating about selling the amp, but I the thought that one day I might be able to have that second system up and running again is preventing me from putting on up for sale.
