Having not heard DPL2 yet to know how much it really brings to the table (reportedly it's a lot for stereo and older pro-logic sources), I can only offer my experience. I listen to music on two-channel, which the 1050 is very good at (Hullguy's not kidding there). If you want good two-channel performace as a first priority, the 1050 is a pretty good place to start. For movies, it's hard to beat (especially if you aren't looking to delve deeply into the emerging 6.1 formats -- although if you do decide to try it, the 1050 does a good job with its "Surround 6.1" for DD 5.1 tracks). For TV viewing, I've switched between two-channel, Pro-Logic, and the "Natural" DSP mode on my 1050. Currently, it's set on Natural, and it works well for us.
