PQ is not why I switched at all; I needed more HD and was tired of waiting a year after D* for everything. I hope D* keeps the HD leader crown although I could care less if they ever add Lifetime or other such channels. Anyways I had both a 622 and a HR22 hooked up to my onkyo 606 via hdmi all the way around then to my 1080p Sammy. I kept switching back and forth to compare because the D* looked better but I struggled to define how just sharper or more real if that makes sense. That said I don't think the PQ argument should even be considered in switching as it is basically a wash and the other reasons carry a lot more weight.I agree that in MOST cases, the PQ difference is small (In the favor of D* in my opinion only). However making comparisons at two different places, on two different TVs, that may be calibrated differently is not an accurate way to judge (I admit, most people can not do it any other way)
