Thinking of an upgrade for my turntable system?


I recently acquired about 200 bucks to spend and I want to spend at least some of it on getting an upgrade.

My current system:
Denon DP-300F with Built in Pre-Amp
Shure M97XE cartridge
NAD C315BEE integrated amplifier
Wharfedale Evo-8 speakers (bookshelf)

which part of my system should I upgrade? I'm planning on buying something off Needledoctor. My budget is 200 dollars, but I'd rather not use all of it, and I'm also iffy about buying vintage.

thanks!

roomtunes makes some "pillow" type roomtreatments that can be secured with stickpins. i use the corner pillows. without them my room is so boomy it is unlisteneable in here. also as an idea, do you have good isolation under your turntable?
Buy the best source material you can find. That will make more difference than anything else considering your budget...

What about a decent pair of headphones? The Denon AH-d1100 are $200. Denons sound very good and are easy to drive. Stay away from Beats and Bose and all that noise-cancelling crap. They are for planes and subways, not serious listening. Grados are cool, but they are open back, which mean you need a quiet room, just like with speakers.
