I am selling my SWR Megoliath cab and SM-900 Head. I have decided on purchasing a Schroeder 410 & 310212 cabs. I would like to know what Amps/Preamps that would work with this setup? I play mostly Modern Hard Rock/Heavy Metal but sometimes I do a occasional Classic Rock gig. One choice I had was a Ampeg SVT-Pro Preamp with a QSC RMX1850 Power Amp. Any others?
