Are Nakamichi amps any good?

As I understand it, Nakamichi bought the licensing rights to the Stasis technology from Threshold, Nakimichi presented their version of Stasis amps to Nelson Pass, who briefly tweaked it, and then Nakamichi went on to manufacture it with Japanese parts and construction.

When you spend a lot of time reading this forum, and others on the internet, you hear about individual issues with every manufacturer. Does that mean that every component is flawed and should be avoided? Of course not. It's one thing to say that a design had issues, but to say that Nakamichi amplifiers "had a reputation for being unstable and prone to failure" is simply NOT true!

The pure Japanese Nakamichi 420 is a superb sounding little amp.Only 50 watts but high current.
Better sounding than the PA7E in my experience.

Nakamichi amplifiers don't need defending. They were highly praised when they were introduced and still well-respected today. Ask someone who really owns one. If you can find one that hasn't been abused, and is selling in your price range, grab it it with both hands. You won't be disappointed.

Just in case.....I have several of the PA-7 and a few PA-7ii amps. Also a PA-5. These will be available soon. The "Stasis tech", was indeed, "used for a time", "Under license", from Nelson Pass. Until he left Nakamichi.
  He left, "Threshold", "Quite disgruntled" I hear. Over some disputes with his partners to go to Nak.. He did go back to Threshold for a time. Leaving finally to form, "Pass Laboratories", and then also, "First Watt". He also designed amplifiers for "Denon" back in the day! And probably for other companies as well.

These amps did NOT have horrible design issues by any stretch of the imagination! As far as any issues that I had with them?
 A nice corollary would be;

{My Ferrari must have design issues because two people stated here, that, "their", "Ford Station-wagon's"? Did not need as many tune up's as the Ford Wagon's did.....}

Fine Audiophile grade Amplifiers like these actually were? NEED servicing now and again. Just as my, "Pass Labs", "Krell", and also my "Manley Lab's", amps do in order to stay healthy and perform at the high levels they were designed to achieve. These were not, "Throw away", amps like many Crown, Pioneer and others were. "Once issues were found in that gear".
 And like a Ferrari, the Nak amps have also held their value "As Well As", Their sound!
 Whereas that old Ford wagon I owned? Who care's? But, It is In the junk yard, I am sure....
