Class D

NAD M22v2 350 wpc will handle 2 ohms

Most of George's post is wrong. EPDR has no meaning really for ClassD.  As well, doubling power with half impedance has little meaning.  All that matters is distortion with low impedance loads.  Most amps that double in power start at comparatively low power at 8 ohms but are still "large" amplifiers. They have relatively low rail voltages. ClassD don't have the same design restrictions as linear amps. An amp that is 400 watts at 8/4/2 ohms has as much capability as an amp that is 100/200/400 watts at 8/4/2 ohms.  What matters is what is the limiting factor.

Some here have no idea, believe Stereophile’s tester JA and his measurements that I posted, he has more knowledge in his little toe, than most of the self proclaimed know all’s here.

Cheers George

I run a class D amp which doubles output from 8 to 4 ohms and is stable at 2 ohms. Also sounds fabulous ( Aavik U-300}. There are other good sounding class D which are stable at 2 ohms.

You can source second hand Aavik U-300s as it has been replaced by a new model. . It has a great DAC and adjustable phono stage. Would expect heavy heavy discounting too as list on Aaviks are frankly ridiculous
