Cloning Class A Classics Continued..



I was recently tempted by reasonably priced "clones" of Pass and/or Krell amps.

Which made me wonder:

If these classic, high end deigns have enduring value, and still compete effectively with the insanely more expensive high end components of today..

...then why isn't someone banging them out on an assembly line, and selling them for the price of dirt, like the Behringer A500 which receives raves in another thread.

Does anyone build or know someone who builds reasonably priced, Class A clones?

Thank you,

Patents used to have a 17 year life, now its 20 although I think its grandfathered. At any rate, any amp or whatever thats 20 years old is now in the public domain, and anybody can build it and sell it, as the Patent system intended.
P.S. I have several patents, but not in the audio field.
Cwlondon - Finding good schematics of class A is not a rocket science but running successful business is very hard. Not only good design but controlling cost is the key. In addition not only good manufacturing and quality control is required but also marketing. Who will buy unknown expensive product especially without reviews? Some magazines like Stereophile tend to review only brands that advertise with them. It requires large capital to start operation and many years to build any reputation while reputation of Pass Labs or Krell might not be achievable at all.
