NAKAMICHI PA-7 & Klipsch safe and sound

Well Moose,  I have the PA-7A MKII amp with a CA-7A pre.  The PA-7 series of NAK amps were a stasis bipolar design.  Smooth in all frequencies with tight bass but I would not characterize them as 'tube like' or warm sounding.  They run in class A for the first 10 watts or so, so given the efficiency of your speakers they'll be driven in class A  most of the time.

The only thing I can say is try it, you may like the more analytical approach to sound or you may not.  Most of the time we prefer what we're used to.

I had a PA7 for a while.Decent sounding amps but why would you use one one high sensitivity speakers?.I also own an Usher R1.5 which is also a Nelson Pass [Threshold] design and sounds better than the PA7 but I think there are much better SS amps to use on high sensitivity speakers.Bakoon for example which sound superb.Which have a zero slew rate.Or even a gainclone type chip amp.

Yep. Thanks. After hookups I listened… hated the sound on my KLIPSCH Heresy 4, so tinny… put my Marantz 2226B back on, and put my PA7 on Marketplace. Thanks again
