That's how it sounds TO ME. Not to you. But TO ME. It is MY opinion. Not yours. I am entitled to my opinion. Gee, this is getting ridiculous.
The HP upgrade is swapping out the "old" (original) 1000W amp module for the "new" 2400W HP amp module, done in the field by the customer. I'm gearing up to do one myself. I *think* the cost is in the neighborhood of USD $400, factoring in sending your original amp back to the factory.
As of right now, the HP (High Power) amp is land-locked to the U.S. due to the 110V fixed voltage...Mark is working on a global-friendly solution 2011, methinks.
