[QUOTE="Silas Pradetto, post: 22668, member: 34"] Re: Time to upgrade my amps... Realistically, in any rig deployed today, DSP will be in use. So whether it is in the amplifier or in an external DSP is irrelevant; the parameters are mostly the same. The Itechs have far, far more DSP horsepower than most external DSPs, and considering you get separate DSP for every amp channel, the possibilities for deployment are nearly endless. Yes, I'm a Crown fanboy; I've owned a ton of the old Itechs and I currently use Itech HDs. I've had a couple of the old amps blow up on me pre-show (they always seem to do it right after powering up, never during), but with so much power available it wasn't hard to allocate a channel from another amp to fill in. The new Itech HDs don't seem to have the same problems the original Itechs did, and I'd say that there are few 'original' Itechs left that haven't been upgraded to eliminate the explosion problems. Remember that power is power- one amp bridged, or two amps stereo, or fifty amps, all producing the same total watts, is still only going to draw about the same amount off the wall.
