+1 on F22
After helping a few folks with Jolida integrated amps, upgrades, then recommended the Black Ice Audio F22 to a buddy to use with his Klipsch RP-600M speakers. He liked the F22 so much, he then decided to move from the RP-600Ms up to nicer floorstanders. The BIA integrated amps sound even nicer with upgraded input/output tubes. KT77s working well so far in the F22.
