I know this is just plain crazy but, I just put in an order for a second Super Twin and a new Carvin DCM3800lx amp to power them. I'll either be using my genz as a preamp and just take the power amp with me when using both cabs or put the carvin in my rack with the VTRM preamp and call it a day. I may be able to use the carvins onboard dsp to add any eq that I may lack with the VTRM. After they break in alittle, these cabs can get scary loud and sound good doing it. I only am going to have a pair because I can. There are very few gigs where I would need more than one, but I'll have them.
