@chadsort -- to give you a direct answer to a question you posed earlier: yes, the Dynavector XX-2 mk.2 cartridge would be a much better choice for your tonearm than the Zu/Denon. the four main parts of the analog playback chain (turntable, tonearm, cartridge, and phono stage) need to work together as one organism. your VPI tonearm just isn't "heavy" enough to make the Zu/Denon work optimally, and your phono stage isn't loading the cartridge properly -- so that's two strikes against you, right there.
that said, since this is your first foray into LP playback, i don't think you need to go all the way to the Dyna XX-2. try a Dyna 20X2L cartridge paired with the Dyna P75 phono stage, set to "phono enhancer" mode. this will sound good and give you a taste of what a decent vinyl rig can deliver.
yes, this will cost more dough, but you've come this far already, right?
