recommendations for the best amp to drive ampeg svt 610hlf cab? I've upgraded my cab .. now need MORE POWER (go figure . currently have the B2RE but it just seems a *bit* undergunned ... cab is rated 600rms, 1200 program handling (does anyone know what that means??). I don't plan to add on to this setup, so looking for something that pushes at least 750 amps at 4 ohms. thanks in advance for all your help!!
