Related to the wattage thread but not covered. I run an Aphex 207d tube preamp into the loop return of my Ashdown Mag combo. I set the Aphex pre at +4, as a result, I get way more db out of the power section than the Ash alone. I've talked to Ashdown and they say this shouldn't cause any problem. But now I'm considering a 2x10 or 2x12 cab to replace the Ash 4x10's and don't want to buy a more powerful pwr amp. The cabs I'm looking at suggest 400 watts and up. Will the higher gain (up to 65db) hitting the power amp compensate for running one of these cabs at 200w RMS & 8ohms? Pros? Cons? I can't seem to get a straight answer from any of my techie friends. Just for giggles, here's my current setup: NS Stick Bass side - EH Black Finger - Ashdown - loop send - Bass Pod XT - Aphex Bass Exciter - Aphex 207D ch 1 - loop return - 4x10t Melody Side - POD XT Live - Aphex 207D ch 2 - Mosvalve power amp - Ashdown 2x10t cab.
