i was starting to look around for a main amp and use my 950 as the pre. I am running a pair of ar 3a speakers which are 4 ohm and these speakers go low meaning down to 1 ohm. The 950 was completely redone and it does drive the ar 3a' s nice to a point then it just cuts out.i know this is a pioneer forum but any suggestions would be nice I was looking at a adcom Gfa 555 but not sure if it would work with the 950
