Which low output MC cartridge

I am in the market for a low output moving coil cart for my Rega P5. I have recently added upgrades from Groovetracer and an HRS record clamp. I am using a Creek OBH-15 Phono pre and now want a low output mc cartridge for under $1,000. I am currently using the Denon DL-103SA, but want to try one other to switch with. I am thinking about either the DL-304, Kontrapunct A, Dynavector 20x or 17 D3. There are also a couple of Ortofon's in the category including the Rondo Blue and Bronze, which I have never read anything about. I know this is a wide range, but they are all in my price range and I am only getting one. Anybody familia with these cartridges who has an opinion (thats a pretty ironic thing to ask in an audiophile forum) on another good match with the Rega, please give me your advice. I am going to live with this for a while, although I have said this about many other pieces of hi-fi detritus that is languishing in my dloset. Thanks in advance.
