Please help! - Buy VPI Classic or keep Technics 1200


I've got upgraditis and am thinking about treating myself to a new audio component for Christmas.  I currently have a Technics 1200 with a Denon 103R cartridge and a heavily modified Jolida JD9 phono stage.  Yes it sounds fantastic but I don't know what I am missing with a VPI Classic or similar table.  There isn't a place close to me where I can go for a demo.  

My question is for you experts - would there be a substantial sound improvement with a VPI Classic  or Classic 2 table if I were to invest the $4,000 in comparison to my Technics 1200?  Would it take the sound to a higher level?  (which is something that I am looking for).  I don't really care about aesthetics or bragging rights but what I do care about is performance and functionality.

 @chakster is correct about the arm, but read up on KAB's tonerarm rewire and fluid damper if budget is low. 
If you like linear trackers the $1k Transfi arm sounds great on 1200s, I also really like the similarly priced Audiomods based on theory, but haven't had a chance to hear one, so take that for what it's worth(i.e. further investigation).

I am thrilled for @slaw , but bet there aren't many Rock 7s out there, let alone soon availalbe used. Cheers,

I talked with Max Townshend two weeks ago. He said his new tt will be out in 6 months. This is why I thought anyone interested in the possibility of a Rock 7 coming up for sale, should be on the look-out then. Believe me, it's worth it!
@sbank for those who don't know: KAB site is down for a few years, it's impossible to open the site. I got those fluid dampers on my pair of upgraded 1210, but it only helps with high compliance cartridges. 

My SP10mk2 in a custom plinth gives me more flexibility with toneaems ("9 or "12 inch). I also have Technics SP20 and i love it.
