I see,
From my own experience, I must say that when I purchased my stuff 20 years ago, I compared different amps mostly similar in specs or wattage with the same equipment in the listening room and you could hear a difference. Maybe when you get to a certain point of quality equipment, that is lest true and the difference is not noticeable.
So, If I follow correctly, I could buy anyone of these amps and it wouldn't make a difference (beside the power), no "musicaly" difference... The only thing to take care of is the source (processor, cd player) and the speakers? I have to say that I have difficulties with that from my own experience.
I am anxious to read the reactions!
