Home Amp/Preamp Asylum

Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: Morri, Appreciate the effort, Dats some deep S*** , Conceptually WRONG ?

"another could prove a class-a fully balanced load tolerant SS amp to be the winner , such is life ..

Unlikely given the kind of distortion pattern it is like to generate.


"Output transformers would be a no no , Driven load and application sets the animal"

Why would output transformers be a no no? Speakers that are pigs to drive are usually terrible with low level resolution anyway...I know only some electrostats and a ribbon or two that are exceptions but for box speakers...forget it.


"we can agree most design metrics suggested will work when designing an SOTA amplifier , be it toobs or sand , but , its not all or nothing ..."

Well, I did mention that SEP or SE(trans) might work to some extent but as the devices are not as linear (maybe Nelson's SIT amp?) as triodes you are back in the harmonic hot water again. SE OTL if you really don't need much power could also be possible, IF you don't need a ton of negative feedback for it to work.



"Could you link the measurement of an SET amp with a flat distortion curve ..?""

You mean distortion vs. frequency I presume?

Here you go:

The Lamm ML2 and 2.1 have quite flat curves...the ML2.1 actually has lower distortion at the highest frequencies.
