I'm beginning to come to some conclusions about the A950Ltd -- it's pretty damn good. In fact, it's exactly what I wanted it to be -- a poor man's leatherhead (and without the leather). It's got nice prat (though not as good as the L3000's), it's not quite as clean (background isn't as black), it's not quite as resolving (but I am not exactly a detail freak)...but damn if it doesn't do a lot of things right. For example, when listening to most music, I'm hearing the same amount of bass, though it's not going as low, it's only on certain recordings that I can really tell where it's going. The opening bass note in the left earcup on Rob Dougan's Furious Angels ("Prelude") is clearly audible on the L3000's, but on the A950LTD, it's inaudible unless I'm straining to hear it (not including compensation for the differences in sensitivity). But switching to Camille's Le Fil ("Au Port"), the bass certainly sounds right. So they must have compensated for the missing lowest frequencies by bumping up the bass just a little bit, but they did it just right, to the point where I can not hear the difference under most casual listening, which is exactly what I wanted. 
 
I'll be getting the A900Ti in a month or two, and we'll see where it goes from there. 
 
Setup:  
 
most listening has been done on Rega Apollo -> Pure Silver Sound interconnects -> Singlepower Supra++, with some done on SACDMods -modded Denon 3910 -> Xiang Sheng 703B, with little attention paid to power. Tweaking consists of your mama touching me at night. 
 
Dac-Ah has been ignored, since it was distorting -- I returned it to its owner to send it off to Pacific Valve to have it fixed.
