Gino, Where did you see the P6k+ price? Usually nakikita ko on Ebay is either $189 or $234 e, shipping/taxes not yet included. I actually saw a new version of the APPJ which is cheaper, but it is smaller in size and has a different set of tubes used (slightly less powerful rating). It's rather cute though.
Yes, for me it is one of the best quality "true" tube amp for P10k-below range. For its price, I haven't seen anything more value-laden and sweeter than this one (and let's not forget "tune-able", because of possible 1 piece 12ax7 tube rolling)
Yes, there are cheaper options out there such as some hybrids, class-D, or solid state amps. But for my personal tastes, nothing beats old school goodness when it comes to clarity, smoothness, warmth, and naturalness that a tube amp provides.
This tube amp certainly deserves recognition and respect in its own right.
