I'm doing a battle right now for what head to use. Either a SVT-CL or CarvinB2000 into a Berg NV215. I used both my dingwall and G&L going to a compressor into the B7K effing cranked.
Long story short, it works just fine through both heads, it's the best problem I've ever had.
P.S. I will say that putting the compressor in front is critical to both setups. That might just be me though, I have the grunt bass on with the lows nearly pegged on the B7k plus Bass boosting on the heads. Damn metal bands!
