very true. It may seem that KeithR has heard neither, nor understood the hype of the then Halcro - superb measurements vs the positive musical reviews of the D'Agostino. M Colloms even states that the Mum Stereo does not measure quite as well as the EVO 402e but sounded quite a bit better
When Dan was on the Dealer Circuit discussing the Momentum mono blocks during one presentation I attended he commented that he has already proven he could design amps with great specs and many leading zeros in distortion. His goal with the Momentum's was to make them sound great and not be overly concerned with how they measured.
I wouldn't make too many buying decisions based on what I hear in any audio store or show. Based auditions at my dealer I was not going to purchase his mono blocks. After fifteen minutes in my set-up I knew they were staying.
