SET Amp question

Is there anything that will minimize the speaker SET interaction?

In the case of speakers that are voiced to be used with high damping factor/low output impedance amps, such as typical solid state amps, I would expect that the tonal imbalance problems which were explained in Duke's excellent response could be significantly reduced by inserting a pair of Zero Autoformers between the amp and speakers.

I have no personal experience with them, though.

If you have questions about how an SET or other 'current source' amplifier will drive a speaker, maybe this link will help in understanding what is going on:

Thanks for the read Ralph! It would seem that the distortion spectrum or bandwidth is more important with respect to the preceived loudness then the intrinsic acoustic power? EG: to make a rig sound less forward one would strive to minimise odd distortions in the presents range ( 1500 Hz).

The Almarro 318B can drive some difficult speakers.I use one to drive Gale 401a speakers and most 100 watt SS amps struggle with these speakers.A 3.5ohm load and 88db sensitivity.
