I just got a 950/755. Replaced a Sony TA-E900ES/HCA-855A.

The diffirence (even w/o breakin) is substantial. Much wider soundstage front and back. A clear sense of weight and ease and not bright. I tried the 950 with the 855A first, much brigther and constrained. The Parasound seems to choke in comparison. Early to say but the 950 in bypass w/ the 755 is quite musical.

Front 3 are VMPS QSO 626 , Hsu VTF-1, Rears Gallo balls.
