I recently picked up a Bergantino HT 322 cabinet. It is rated at 800w at 4ohms. Beautiful cab. I am currently using an Ashdown EVO II 500w (1000 peak), with 4 ohm min. load. It sounds great, but the amp is pretty beat up (and [mythically?] underdrives the cabinet) and I am starting to consider finding something new and better fitting for this great cabinet. Any suggestions?
