I don’t like to get into listing brands, when many commenters throw out a lot of brands, it gets confusing. There are about 30 audiophile brands, all well reviewed and proven. I often recommend the British Audiophile’s youtube channel, once, a year he reviews 10 or so amps. I think if you narrow down your search, the specs, the budget, the house sound, you would end up with about 10 or less amps.

I like smaller brands such as Creek and Belles, Simaudio (not as small). They are optimized for maximum clarify and detail developed by mad scientists. Enjoy your hunt!
IMHO cheapaudioman is an entertainer not a reliable reviewer.
