Upgrade cartridge or turntable?


I have a Rega Planar 3 turntable with an Ortofon Blue cartridge which has served me well. I’ve had them both now for two years and am around the 1000 hr mark which in itself draws debate.  I’m looking for opinions on either a cartridge upgrade, or a turntable.  Can go to 2000 for TT, also considering MC cartridge which would involve a new phonostage.  Let’s hear it.

@miketee Couldn't agree more with you on the clunky VTA adjustment by spacer only.  Such a ridiculous design.  Then you have the lack of azimuth adjustment.  Honestly, why would anyone consider upgrading a cartridge on a P3 if it's nearly mechanically impossible (due to flawed table design) to set up the cart properly????

This is why he could upgrade only the stylus, but the cartridge was sold with this arm/turntable, no need to adjust anything.

In my opinion Rega turntable is a cheap plastic toy with a belt. My strong advice is upgrade to Technics direct drive, SL1200GR is under $2k new with warranty and slightly cheaper if used. Same Ortofon 2M can be used and properly adjusted on Technics tonearm like any other mid compliance MM/MI or MC in general. 


Lots of great and practical advice here.  I have spent extra on isolation platform and power conditioner after I purchased the TT because frankly, it didn’t sound too good. Those two items were more than the cost of the Rega, but they did make a huge difference.  I did find making adjustments with the arm difficult, and being that this was my first jump to a better quality table was annoyed that there was no ground wire, being that I was having noise issues that were improved by the conditioner.  I looked into a new stylus, but it was almost as much as a replacement cart. I may look into the stylus replacement from one of Ortofon’s other cartridges although it will still be close to a new cartridge.
