J.B.... I guess I got a bad impression of high-level sub setups because no on seems to be using them for the most part, if given a choice, and I recall one guy writing about being content with his speaker-level setup for 2 years until one day he removed his speakers from the sub and attached them directly to the main amp and was blown away by the improved performance. I thought, dang, those speakers weren't getting the proper wattage passed along for 2 whole years... what a sunk cost in time!

Thanks for all your words of advice Ken, JohnK, ClubNeon and JB... it's been quite informative. I went and ordered the EP400 in the end. Thanks again!
