I'd throw a Dynavector 20 XL or whatever suits your budget on the table - the Planar 4 can definitely handle a big cartridge upgrade no problem.
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.
