Hi,
probably does not sound again using the CFB architecture
however you look at this project
it seems to me innovative:cool:

Right hand side is just two Marantz HDAM-SA2 module schematic, with the second changed a little bit.

is exact
it seems to me an extremely linear

the same configuration provides total compensation of the two complementary branches:)

This looks very interesting to me. What does a SIM indicate for performance? And, will you build it and test/listen?

Hi, Stee doesn't bother with simming, building or testing his circuits, rgds, sreten.

We just get the benefit of seeing his ideas about circuits he doesn't seem to understand.
And classic howlers like in post #6, that has two diodes across the VBE multiplier.
