The added benefit of the new models is that they have digital inputs as well. The executive summary is that these are perfect amplifiers that behave impeccably, even under difficult loads. They will not add to or substract from the sound. Harbeth will use an AS701 at the upcoming Bristol audio show, to demonstrate their P3ESR. The argument is that you do not need expensive electronics for excellent sound.
