What you want pretty well describes a Grado Sonata; the only difference being that the Sonata is better in all respects than the best qualities of either mentioned cartridge. It out-Grado's the Gold on the low end, and its closer to a decent moving coil than the AT on the high end, with tons of richness and detail in the middle.
Find a dealer to listen to one, that will make the decision easy.
Yep, it's my favorite Grado for price vs. performance, but at $500 new it's a bit out of his league....
It also may hum like crazy on a Rega....
One of these days I'll scan in an article written by Corey Greenburg and published in the now defunct "Audio" magazine about what he did to get a P-3 quietened down enough to enjoy a Grado Platinum....
And while I haven't heard the Denon DL160, I do have an earlier DL-300, which was not an expensive cartridge listing for $100 back in the '80's, and is a low output version of the 160, and it sounds dyn-o-mite!
The DL-103S Shibata I have is also a different beast than the normal conical stylus in today's DL103 and it is really the only one I've ever listened to, but it's also a great cartridge...but unobtainium....
