If this really is A/B topology, that's extremely disappointing. With the provided supply capable of only 48W input power, and being that A/Bs are about 50% efficient (and that's ONLY at max output), that means this amp can only produce a max of 24W combined across all 3 channels, while dissipating 24W of wasted heat. At lower output levels, efficiency is worse!
PE - please check to confirm the topology. I was interested in this amp, but not if it's A/B. While PE is not the mfr, it would be wise to get the most accurate info about the products you sell. I love PE and have bought a lot of items, and had such hopes for this amp, but thus far it looks to have far too many cons #6dB LPF, A/B topology, no WAY the output specs are accurate) if they are true.
