One thing I've found as I've "progressed" through the hobby, is that I suppose the "pessimist" way to say it is it takes less and less to impress me. Perhaps the more accurate way to say it though is I'm impressed by more and more subtle things. I suspect this is the case for a lot of folks on the forum, and I think you need to take that into account when you read/interpret things like an Anamorphic lens producing a "wow" effect. It seems like when you start, differences/improvements need to be much larger relative to the cost, but as you proceed/learn, well at least I seem to be willing to spend increasing amounts of money for smaller and smaller improvements, yet I still find them "significant".
I got a used Panamorph P752 early on in the hobby and it was great, and it was cheap. After a couple projector upgrades I upgraded to a Prismasonic HD5000, which was a lot more expensive, but a significant, and IMO worthwhile improvement. I've added a Lumagen Radiance XE, AVM 50V (ARC), etc.
I guess what I'm trying to say is, I don't know that I'd ever say an Anamorphic lens produces a "WOW" effect, the difference is subtle, yet significant, like the more "solid" (best way I can describe it) picture I get with the Radiance.
