Alright. I spent a good four hours again researching amps tonight and then just said enough is enough. I searched for good prices on the ones I was considering and since the Behringer Inuke 3000 with DSP isn't out yet, and the Peavey IPR3000 isn't yet well vetted for specific subwoofer use yet by our community (and has no DSP until you pay nearly $500) I just went with the tried and true EP4000.
It helped that I found the EP4000 brand new for $263.10 shipped from uniquesquared.com (never ordered from them before nor even heard of them before today, but they have 9.3 out of 10.0 score on reselleratings.com which is higher than Amazon, walmart etc.)
Steps to get this price (listed at $299)
1. Create account at uniquesquared.com and login to earn 500 points ($5, but creating a login is also required to get the 10% off coupon code to work)
2. Sign up for e-mail subscription to their deals and get 100 points ($1)
3. Search for EP4000 listed for $299.99 (10% off code works with other amps I looked at too)
4. Add amp to cart and use coupon sxsw2011ms
for 10% off
5. Use the points you get for signing up and subscribing to their mailing list to save an additional $6 bucks to bring it down to $263.10.
6. Use UPS Ground for free shipping.
Note: You'll also earn like 600 points in the purchase that you can use for your next purchase ($6). Also if you bought three things at once you get an additional 500 points ($5)
If anybody else is looking for a good deal on a EP4000. That's the best deal I could find. I'm going to post it in slickdeals.net as well to hopefully help somebody else. I'll keep an eye on the future prices of the Peavey IPR 3000 with DSP and Behringer DSP 3000, and if they prove to be good sub amps I may sell off the EP4000 and pick up one of those instead. The power savings would be significant. The EP4000 idles at 65 to 100 watts from what I've read and consumes a couple thousand in heavy use. The Class D amps technology that the Peavey and Behringer use is supposedly much much more efficient at both load and idle. I know the KC sub gathering alone in one day raised my electricity bill by $20 that month (I pay close attention to my bills) so I imagine the more efficient amp would pay for itself over it's lifetime in electricity savings.
