I listen mainly to music but wanted surround sound too. I have a 561 processor, M60 fronts, M33c Centre and M33 rear surrounds. The sound is awesome considering what I paid. All my equipment is ex-demo. The M60s were �1500 (�2500 new), 561 �2000 (�2850), M33c �550 (�775) and M33's �899 (�1500). I listened to the DSP speakers and didn't personally think they warranted the extra outlay over the equivalent non DSP actives. Likewise the 568; I'm sure it's better than the 561 but at �3800 plus the cost of a 562v I personally didn't think it was worth the extra cost.
