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,
