Well, I figured someone would chime in before now. I have a Nak PA7 and I think I am going to put it on ebay. It is a very smooth sounding amp, built extremely well with high quality parts. Has been a really reliable amp. It actually sounds like a "sweet" little smooth good 60 watt amp even tube like. Even though it is a monster amp with a huge power supply IT IS NOT A BASS AMP. I bought this Stasis/Pass design because I could not afford the Stasis 2. In my opinion the Stasis 2 sounds similar, but it has much more authority in playing complex loads. I have heard if you update the Stasis 2, it is a killer amp. Larry
