I assume joey meant single-ended class A.
Tuonunez, I would agree that 88dB/4 ohms is not a good match for single-ended, unless it's an 845. But that's a lot of heat, weight and expense. $4K is a healthy budget for a quality push-pull tube amp. 40-60 watts would work fine. Look at Black Ice, Rogue, Prima Luna or Quicksilver. Personally I would not buy a Chinese amp, and not for political reasons. You just don't get much support. OTOH, if you're at the "end of the world" your choices may be limited to Asian distributors or maybe some EU companies, I couldn't say.
