Nakamichi PA7 versus PA7 II

As the owner of a PA7 II can tell you it was rated at 225
Watts per channel into 8ohm vs 200 for the PA7. I don't believe they're class A but the do utilize the Stasis topology designed by Nelson Pass. This amp runs warm but not hot so if it's class A it's only at a small percentage of the rated power. That's all I know on the topic. BTW the PA7 II is rated at 325 into 4 ohms.

Thanks for your feedback.How do like the amp?Considering the age of the amp doesn't need new capacitors?

I have a PA 7 II and love.I run it hard into PSB gold's and it works ver well.

This is related to the "Stasis" topology sound. I have a TA-4, the 100 w/ch reciever of the same Nelson Pass series. A nice amp with lots of guts, I use it in my video set up. For audio, when compared with other components it was more than a little rough. I know the PA 7 is a different animal, I'm just saying: listen first, buy later. (unless you are price/resale protected) good luck.

Walther,

I think it's a fine sounding amp. I had it modified by Musical Concepts. I'ts not bright but maybe a touch warm.
A good power cable (I use Synergistic Res Ref) makes a
positve improvement.
