The above mentioned Black Ice ( formerly Jolida) is excellent. I have their F35. Great bang for the buck ( 3 K I believe when ordered with KT 150’s)
I also have two Chinese integrated amps....The MUZISHARE X 7, and the Willsenton R8. I prefer the Willsenton over the MUZISHARE. With tube rolling I might also prefer the Willsenton over the Black Ice, however haven’t done any side by side yet.
The Willsenton has only been here for less than a week, so can’t speak to long term reliability yet. The MUZISHARE has been here for a year. No problems so far. As far as build quality all three amps are very, very good. Both Chinese amps are available on Amazon for approximately 1500.00 delivered. An outstanding value in my opinion.
Cheers.....
