New Precision Power amplifier opinions.

Not to hijack but has anyone compared the PPI P900.4 to the Soundstream Reference Ref4.920 Ref4.920? The Ref has slighlty higher wattage, is Class A/B, is much larger, and is $40 more than the PPI. The PPI is Class D.

I am also curious as to what is different about their sound, since you can now find Soundstream Reference's closer to the same price.

The Phantom is way more efficient, I am able to run 3 if them with essentially a stock electrical system with zero voltage drop.
