Class D

The ICE 200AS2 has this same graph which shows a phase shift of almost 90° . I've never seen these types of plots presented this way and they don't do it for all their models.

I've seen that graph on other forums it's the amplifier phase which will be run through feedback. What's the reason for posting it?

It's not an integrated but the March Audio P502 stereo amp is rated to 2 ohms. Sounds very good with Revel speakers. If you're looking for silly tweaks that either do nothing or degrade the amp look elsewhere this guy doesn't buy into the voodoo just gives a great performing amp for a decent price.

Benchmark AHB2 amp is not Class D. 

I don't know George some of the best sound quality  I've heard came from Class D amps in active speakers. Effortless from top to bottom. 

Congratulations George you figured out how to make those Ncore modules sound like bad 1980's tube amps. 

To me the best sounding amp doesn't have a sound.

I probably would like the Kii 3, I like the Dutch and Dutch, Buchardt, Genelec, Adam. I also like Revel and Kef passives. This list isn't all inclusive. 

George you might like the Adam S3V, it has newest ICE amps switching at 1Mhz on the woofer and Mid driver and their own AB amp matched to the tweeter.

Thanks George but perhaps someone who understands the question might answer.

This graph https://ibb.co/MS3xC6M I have seen on other forums but I never quite understood it. Is it showing that the impedance at 20Hz is .005 Ohms which stays fairly flat to 1Khz then rises to .05 Ohm at 20 Khz? The phase shifts 70° from
.025 Ohm to .015 Ohms across the 20hz to 20 Khz? This is the electrical phase of the amp? If so did they adjust for time delay ? I don’t really understand all this but I don’t see how the electrical phase of 70° over a .10 Ohms is very relevant to how an amp deals with a speaker?
