My eventual plan is to pickup another pair of QS8s for a 7.1 system and get a nice sterio, dual mono, or pair of monoblocks to power the M80s. If this is the case do you really think I need all the power of the RMB-1095 or would the 1075 do for now?
Just to note: some other 5 channel amps I have looked at are the Parasound A52 and the Butler TDB 5150.

In terms of an amp for the M80s I would really like to get a high powered tube amp. I have played guitar for about 10 years now and any of my amps are tube, so I have a slight preferance towards them.
