I have been thinking of getting a power amp and combining it with a nice pre-amp. I'm not really sure of what to get and what combinations will sound the best. I have looked at some Ampeg Pre-Amps and well as the BBE and the Sans Amp RBI. Also looked at some QSC power amps, but I'm really clueless with this one. I have always used regualr amp heads. I will be running this through a Mesa PH 212 cab with 600w handling. Any help would be great. Thanks!
