Gonk has the technical part covered, so I'll offer a subjective view. I struggled with very similar issues for quite a while before finally ordering a 1050 a couple of weeks ago. The 1050 works perfectly for my small, simple room, and sounds excellent. I'm very happy with it, and it's NOT going back!

As for DPL2, I have it on another system, and must admit I'm not a big fan of it.

I'm confident I made the right decision by going with the 1050 - probalbly should have done it sooner. Just my .02.
