IMHO you won't find a better cart. than Dyna until you get over about $1k, other opinions may vary.
Best $500 cartridge? Dynavector DV-20XH?
I'm looking to upgrade from my Grado Gold cartridge, its about a year old, and i've heard good things about the Dynavector DV-20X 2.5mv output. I have a killer channel islands VPP-1 phono preamp with VAC-1 power supply and custom DH Labs IEC cable. the cartridge is going on a Project carbon arm on a modded Project XPression table that's also a year old. Any suggestions other than Dynavector? What would I gain from upgrading to the $500 range?
