I'll start by saying that I own both units and I actually prefer the 949 (slightly). I have read that the only differences between the 2 are in the the A's ability to decode 4 channel better. Since I do not own a Quad turntable/cartridge and/or quad lp's decoding ability is a mote point to me. I am able to input 4 ch through front and rear outputs from my denon dvd player to front and rear tape inputs. Works like a charm. In looking at the "innards" of the two units there is a marked difference. The 949A makes use of more "modern" technology in use of integrated circuits and a difference in the associated boards, whereas the 949 is "transistor" challenged. (lots of them). Since I am technically challenged that's about as much as I can speak to the differences. As to the sound, the 949 is very close to my SX-950, whereas the 949A is a little brighter..more like my SX-980 and 1080. I have never found either unit to be power starved at all in 4 channel mode..even driving my KLH's which do take some power. Would welcome any of your observations of the QX-949's. I prefer the 949 over all of my other Vintage Pioneer units plus I like its flexibility to adjust volume and balance between front & rear.
