Regarding my last post, I erroneously inferred and believed that the Benchmark AHB-2 was a Class D amp, when it isn’t. In fact, Benchmark’s specs state it: “combines class-AB, and class-H topologies, using a feed-forward error correction system” (https://benchmarkmedia.com/products/benchmark-ahb2-power-amplifier). And ACHiPo (Evan), is using two AHB-2’s that are in bridged mode to output enough power for his SoundLabs. -Mike
