Their marketing is continuing the exaggerated HDAM benefits, anyone who thinks logically should know the bs part about the false claim that it drastically improves the speed of amplification, false in the sense that no matter how fast the hdams can do, it is not the speed bottleneck in the signal path.
Good marketing as bs, but sad for engineers and others who understand bottleneck analysis. Other than that, imo if 13 channel is enough, the AV20 is, imo, a great alternative to the Anthem AWM90 and the AV10. If the dac is the same es9018k2m in the 10, then it is a plus. That one is consider “reference” according to ESS, cheaper than the AVM90’s 9038pro, but no one can hear the 122 dB SINAD the 9038pro offers vs the 9018kem’s 120 dB anyway.
