Upgraded turntable - is my current setup sufficient?

After some research on table upgrades from my denon dp300 with the sumiko rainier I pulled the trigger on the Marantz TT15-S1 with included clearaudio virtuoso. Based on some threads on this forum and some others it seems that any table under $1000 wouldn't yield the kind of audible jump I wanted.

Currently I have an adcom gtp500 for the phono stage running into a rotel 1066 pre-pro and the rotel 1080 amp. Those are driving a set of cambridge soundworks tower 1 speakers.

I am hoping to hear an appreciable difference with the new marantz and virtuoso running through my current setup.

Does anyone think otherwise?

If so let me know any suggested changes and what order they should be made. I've checked the specs - the adcom amp should have no problems with the virtuoso cart. Having said that, is there a better phono stage upgrade I can make for under $500 that would be noticeable difference?

I picked up the tower 1 speakers last year for $150 bucks and I've been super happy with them. Im hoping the marantz won't underperform due to the speakers or anything else, and will provide me with the appreciable difference I am hoping for.

Thanks!
