DENON POA-6600

JarreYuri · 30th May 2012, 02:31 PM

Hi!

Can anyone verify the information I read on the net that the Denon POA 6600 was designed by mr Nelson Pass?
Is this true?

This amp has a typical Denon generic triple serial differential topology
wich can be found in many Denon amplifiers as well as other
japaneses amplifiers of the late 70s/early 80s.

This architecture goes back to a notable 1973 paper published by Otala/Lohstroh.

Fairly right..

Denon and others often used fets for the input differential.

It's just a rumor from Audiokarma - of course it isn't true.

The audio world is full of lies, mostly made up by people selling their old equipment, hoping to make a bit more money from it.

Yeah, I found it a bit awkward.
