Hi, Mr. Pass,
I wonder if the amp discussed here http://www.diyaudio.com/forums/showthread.php?s=&threadid=23590&highlight=
is the same principle as your patent I attached. Both wanted to make classA with another floating big current power supply.
The technics amp uses 105V power supply. If wanted to make it class A, does the second amp has to be biased at 0.5x(105/8)=6.5A for 8ohm speaker, or could be less than that like only 1A bias at second power supply?

Hi. Mr.Pass,
So, The technics AA amp is based on Japanese patent. I tought it based on your patent that I attached. They are very similiar in principle.
Mr. Pass,
I never saw anything as schematic or commercial amp using your patent that I attach. Have you built something based on your patent that I attach?
Your patent on "clever bias" ends up in Hawksford Error Correction and NP-PMA Error Correction.
Your patent usually ends up in very clever cct.
(This is something special too. The one and only who "begins" it never uses EC, it is used and become popular by other guy. WHY?)
But how come I never see anything related to your patent that I attached?

The market will only support so many amplifier designs before people begin getting confused. Right now, Nelson has two different designs--X and XA--in the market at the same time. Both are unconventional. Given the stark inability of many salespeople to comprehend even elementary concepts in electronics, it's unlikely that the average customer is going to get a reasonable explanation when he asks what the difference is between the two. Add a third topology and they're likely to walk out without buying anything after hearing the salescritter yammering for twenty minutes about things he clearly doesn't understand.
In theory, the answer to this is education. In practice, it costs money to send a "teacher" around to each dealer to enlighten people. Such things used to be left to the regional sales reps, but they were frequently just as lost as the sales force. A case of the blind leading the blind. Whether Nelson goes through reps or direct, I do not know. At a guess, I'd say that he works direct; seems more his style.
So who do you send out to do the education? Well, that's a problem. There simply aren't that many people who understand the circuits, and fewer still who can express that knowledge so that others can pick up on it. Nelson understands the circuits and can express it, but he has more fun in Foresthills playing Mad Scientist. Endless miles on the road trying to uplift the masses is a thankless task. Worse yet, you've got to get out and do it all again next year because of turnover in the sales staff over time. Whew! I'm getting tired just thinking about it.
Besides, Nelson needs something up his sleeve for the day when the X and XA sales begin tapering off.

Every patent NP made is extraordinary. CCS patent ended in legendary Aleph series. SuSy patent end in current X and XA amp.
Every patent works beautifully. To me its beautiful, because there are so little component involved in the patent, resulting something extraordinary. It's ART.

Hi, Grey,
Are people buying new audio power amp just because something different in the cct? How about for the better sound? 😀

Yes. Those patents are made more than 10 years ago. I wonder what kind of patent NP is having RIGHT NOW?
That's it. It's not "Not using it". It's just "Using it next".
