I'm currently running a GK 700RB head with the 210RBH and 115RBH. I tried out the Sansamp DI a few weeks ago and decided I really liked the tube sound. I just got an Ampeg SVP Pro (on the way) and need to decide on the amp. I plan to run bridged at 4Ohm. Is 1200W enough? Is 1600W over-kill? All the talk on here about Epifani and Bergantino is starting to give me GAS. Do these speakers sound noticeably better than the GK's? Has anyone compared the new GK "Neo"?
