Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???

The 300 uses a different module than the 700 simply because it is a stereo amp; the 700 is a monoblock.

Hello tweak1,

FYI: I had 2 EP 100.2SEs (with upgraded fuses) for well over a year. I got the bug and bought a Audio Alchemy DPA-1 stereo amp. It is much richer in the midrange and bass, deeper and more holographic sound stage= much closer to real music."

     Good to know, I'm always interested in learning about other good class D amps.  Thanks.
     I currently use my EP 100.2SE in bridged mode to power my Magnepan CC3 center channel speaker and my ClassD Audio unit in stereo mode to power my rear surrounds for HT usage.  I have no current complaints but I'm always open to upgrades in performance. Lots of very good class D options now available that I'd like to audition.

Thanx,
  Tim 

Thanks again guys!   Some great suggestions.  I’ve got plenty to go at & will be hearing a few over the next few weeks.

I wrote a big long thread cataloging my Class D/T history, but my browser must have refreshed & lost it.    Lesson learned, I’ll cut & paste from a word doc in future.
I’ll rewrite it when I have time.

Gallium nitride (GaN) semiconductors may be desired over silicon carbide (SiC) for power transistor applications because of the greater bandgap of GaN’s 3.4 eV compared to SiC’s of 1.1 ev, but there still exists a fundamental challenge of not being able to grow pure GaN crystals any larger than about 2". This is a limiting factor from a manufacturing standpoint for the general uptake of GaN in power applications; most manufacturers have to use a doped version which is poorer performing and more expensive compared to pure SiC crystals, which can be grown to double and larger sizes. Also, gallium is a rare earth element, silicon, um, not so much.

I have immunity against monkey plague and Class D amplification.
