Where to spend some money?


Would welcome anyone's thoughts on how to spend some money to step up the quality of my vinyl playback. This is by no means a mega buck system, but here is what I have; Rega P-2 with RB-250 and Exact cartridge. I Have installed the Incognito rewire set, machined sub-platter, and an Iron Audio thick acrylic platter. I clean my vinyl with a Nitty Gritty and a carbon brush. The preamp is a Hagerman Cornet and the interconnects are PBJ's. This is fed into a Rotel RB1080 200wpc amp and out to Paradigm Monitor 11 towers. I use the preamp section of a Rotel RX1065 receiver to control processing functions. It does sound pretty good in my opinion, but I know there is more to be had

Where would around $1500.00 to $2000.00 best be spent?

Thanks for your time.

Thanks to all for your advice, much appreciated.

I wish I had $10,000.00 to spend now :)

Regarding the Studio 100's. Are they definatley a cut above the monitors?
They are the top of the line, which all others derive their attributes from as well as try to emulate. Just look at the lineup http://www.paradigm.com/Website/SiteReferenceProduct/RModels/StudioSeries/StudioSpecs.html Speakers are always a huge upgrade.
