Dynavector 20X smokes any of those that you mentioned. You can get it in either high output (20X-H) or low output (20X-L) configurations. This is easily the best sounding cartridge in the $500 and under category. The big brother, the 17D2 is a major babe for $750 but it is only available in a low output version.
But those would be my top two recommendations, hands down.
