Sean, I don't know what you mean by 'measurably better' as there was no test equipment in sight, but I accept your favorable opinion. One criticism I have is that connections are recessed into a small triangular well in the bottom of the amp, making use of many cables impossible - the mono amps were demonstrated upside down, which may serve to illustrate. I hope they will address this issue in the future. The amps run cool.
