I just ordered my mt22s, plan on having those with qs8 and a vp 100 here in the next few months as pay checks allow. Thinkin im going the svs root for the subs. However Im moving a set of large cerwinvegas i use for partys downstairs now which i had run from the pre out section of my onkyo 797. There hooked to a qsc rmx 1450, dont get me wrong that combo wasnt to sound good, just loud and somewhat clean cause it has headroom. But i need now a seperate cheap preamp/tuner for that any suggestions.
