REL Strata III vs. REL Q201E

Okay, I auditioned these the other day. The problem is, I liked both of them in the store. The Strata III produced a very encompasing bass presence that filled the room and had just a slight linger. The Q201E had some rather impressive punchy bass, that was slightly directional due to its forward firing driver, but the bass died rather quickly. I believe both of them have the ability, aside from home theater duty, to mooch off the amp signal and incorporate into regular 2ch listening. As the listening room I heard these in was more for home theater, I was curious which one everyone here feels would be better for 2ch listening? I took the Srata home for demo, but all I have connected it to is the home theater. The bass was good, precise, but honestly not as full sounding as the sub I replaced, M&K V-125. I hope this is due to a break-in period that the sub might need. If it doesn't get much better I don't know if I can justify the $1200 price. I thought about moving the sub to the side wall or a corner, but won't that kill any proper stereo listening? Tonight will try it out with the main speakers, B&W N804s, for stereo listening. Perhaps I purchased too small a sub? Maybe I need a Storm III? My room size is about 17x15 with carpet, a fireplace, furniture, and is open to the kitchen on one side.
