I have one. Amazing sound other than, say, below 60Hz where it kind of flattens out a bit, and it looks absolutely stunning. I would think a tube upgrade would take it up even another notch.
Jolida Fx10
Last week I purchased the Jolida FX10, not knowing what to expect I was skeptical that this 10wpc integrated tube amp was going to sound so superb. I paired the amp with PSB B25 speakers rated at 91bd efficiency and I wow the sound is practically magical. What a nice little amp and for the price of under $500 wow, great deal!
