I do not disagree because I simply don't have the experience to do so (and I do not have golden ears) but I will say that my Proceed HPA2 mentioned above, driving the Aerial Acoustic 8Bs through an AR LS-16 tube preamp sounds good as high as I care to crank it before the neighbors start to complain. Remarkably, it sounds pretty good at lower volumes as well. There is no point in the volume range where they get too bright or too muddy for that matter. But, as @sameyers1 mentioned these speakers and this amp seem to have been made for each other.
The one exception is overly DR compressed recordings. The louder they get the worse they sound.....on all but my lowest end systems.
