Sean; My experience with the 2150 was plugged into a CJ PV-6 preamp (not the highly colored 5, beautiful as it did sound though). I felt it to be the ONLY amp at the time (1983)that had the correct slam,lack of mud, weight and authority to run the bass columns of the Infinity RS-1. All other choices at the time were not as good save the Levinson ML-3 at way too much money. I am not sure that it was much better if at all. Trying the 2150 on the top yielded exemplary neutrality and smoothness. The 1150 was even better on top, but not on the bottom as you referred. I dont know why the dealers (like Lyric) dropped the line after the 3000 series came out, but I am sorry I never was able to listen to them. I thought the Design, fit , finish, style and sound of the 2150B, was amazingly good for the price, surpassing the Bryston 4B of that era.
It is allways in the back of my mind that parts quality deterioration has occured in 20 year old units, and the sound we remembered does not duplicate today, because of this. A real concern.
As far as the 2150 running out of steam, Sean, they never did that when I had them. In fact, we would constantly be in awe of how ballsy that thing was. All in all,a company that is surely missed. They were honest products. The preamp and tuner were darn good as well.
Regarding those Acoustats, the Perreaux drove them better than the Acoustat TNT amp. I remember the comparison. A testament to that amps ability with those wacky impedences.........Frank
