I think you may well be making a lateral move. I doubt you will gain anything from that expenditure. Unfortunately to get any realistic gain your budget is way too low.
Turntables are essentially mechanical devices and so superb engineering and craftsmanship can bring significant dividends. What is it you don't like about your current turntable?
Since I have Audio Technica AT-LP60-USB turntable that has everything built into it's tone arm and comes with the Audio technica AT3600L, I was hoping to gain some detail and resolution with a better cartridge. I was also hoping to gain some added comfort knowing that I wouldn't be wearing out my albums with a subpar turntable.
The fact the turntable is all plastic with hard plastic feet, it would be nice to upgrade to something that is a wood body with some vibration resistant feet so that my SVS subwoofer output doesn't bleed into the stylus with feedback. While I never yet have had the volume up on bass heavy tracks to see this on the LP60-USB, I have on my previous cheaper turntables.
I was wanting to go with a AT-VM95c/e cartridge but I have read that the Ortofon OM 10 is decent and better than the 2M Red for sound quality. I also red that the Ortofon OM 10 is a decent competitor to the VM95 if not a bit more detailed, if not a bit brighter. The 2M Red has been said my many to be too bright where the OM 10 or 2M Blue is much better.
For that reason, I'm starting to really think about the Fluance RT82 ($350) which seems to have features and performance on par with many other makers $750 turntables.
