Bel Canto offers some affordable fine audio amps in their line up.
Bel Canto has been around making fine audio products since 1991 and all are made in the USA.
I have heard at least one of their amps in the e.ONE series a number of times. The e.ONE line gear is small and very easy to fit into tight places, but the sound is big.
