Is this Meridian 258 a step up from Niles Multi-room 6430 amp?

I find the sound quality up and above that of the Niles and Russound multiroom amplifiers. Add in that it runs cool and you have an excellent combination.

What class D platform is the 258 based on? Is it documented anywhere? Hypex NCore amps are superb. It's not based on hypex, based on what I can see. I would bet it's the B&O ice that M has used before. I wonder how much of this amp is similar to the amps in the DSP speakers? I didn’t realise DSPs used Class-D amplification - I thought the legacy speakers were Class A and the more modern variants were AB?

Even the 8000's haven't had nearly enough heat sinking or power draw for their claimed output power in class A.
My guess is that they ran the small-signal stages in A, and biased the output stages for class A up to something like 20 watts, and then switched into A/B.
