Hi again Rinpoche, "problem" is that by listening to M625 S2 you have set your reference point very high. I suspect that if you get any other amp, including Continuum S2, you will place yourself onto a path of regrets and second guessing yourself, followed by an unavoidable course of "upgraditis furiosa".
Rather, why not try to megotiate a price break with Angie?
