I had the Parasound A23 lying around here so decided to give it a go with XLR cabling and good speaker cables. I really felt the in your face feeling you described, highs were unbearable, really sharp, some bass but not worth it to be honest.
Plugged the Crown XLS 1500 back and it sort of feels like heaven. Everything is more controlled. Of course the floor noise was there when I connected it and the interface was off, but whatever, I think it's worth it.
I think I'm done trying amplifiers after this, maybe if I get a Crown XLS 2500, but I'm wary of blowing the speakers using that much power.
I got a Dynaudio Center LR120 (or C120) to go with this setup. I sort of owe my audio dealer (the A23 is his), feel like I should buy something from him, but what I really want is to get another cheap Crown and rack on top of the one I got to drive the Dynaudios.
thanks for all the advice...
if it helps, some good songs to test speakers are made by the artist Woodkid. Try Iron or Run boy Run, really hard for these to sound sublime...
