new GAN amplifier

We seem to be freely mixing new solid state technology (GaN), output impedance,and power supply current delivery .
A bit more structured logic would help.

All 8 of my current class d amps are rock solid and not going anywhere but I feel good knowing that as time goes on there are more and more great sounding and cost effective options out there.

The larger Bryston 4B SST2 puts out 300 at 8 ohms, 500 at 4 ohms, and the tech estimated 600-700 at 2 ohms. Definitely better, but unfortunately all this doesn’t correlate with the sound.

Yes you are correct Viber, I myself never liked the Bryston sound, and I put that down to just one of the things that I've never liked and that is that they use an excessive amount of global feedback, to get their specs.

I myself prefer much less feedback (so long as the amp still achieves good measurements) and also if the design allows the use of just local feedback (again so long as the amp has good measurements).
EG: my ME amps, Gryphon’s, Agostino, early Pass ect ect

Back to the 2 ohm thing, hey George.

Yes MrD, and they are needed if one has some of the very best speakers around which dive to 2ohms or even lower, and you wish to get the very best out of them with no compromises.


Cheers George

George,
Even though Pass may have less feedback than Bryston, I hate the euphonic sound of Pass.  There are many more factors determining the sound than the amount of feedback.  

Many (me included) just don't like Mosfet sound. 
 Listen to some older Threshold Pass amps that used bi-polars, you'll change your mind.

Cheers George
