If you didn't do a proper dual blind test, then this is of no use. You need to listen to these amps under controlled (level balanced), blind scenarios. I have, like a few other members including ADTG, had many expensive amps. We have also enjoyed many expensive speakers such as the BW 802D2, RBH SVTRS, etc.and it is very difficult to separate them, especially when looking at them. Before getting the ATI class D series, I had come from a Mcintosh MA7000 with Focal 1028BE and then an MC452 amp with BW802D2 and all Mac gear. The reality is, they are all good. Unless blind, you can't honestly tell them apart. That Benchmark is probably one of the best measuring amps in the market right now. The Levinson looks better. The mind can play nasty tricks on you and that Levinson looks badass... Just as if you put the BW 802D3 next to the RBH SVTRS, there is no way anyone can say the BW sounds better, the RBH literally TOWERS over them, and anyone next to them. Personally, I think they really do sound better, but the point is that the mind plays tricks on you...
