Rega phono cart,s that can be used without spacer


Does anyone out there know of phono cart's. that can be used with Rega tables such as P3, P5, RP6, and Rp8, without having to put spacers in to insure the correct VTA? I love to change cartridges, but the Rega arms discourage this, and Rega apparently wanst you to use their phono cart's: Bias, Elyses, Exact, etc.

Hi Matt .... It's great to learn that you're happy with the Nag on our table/arm. What protractor did you use to mount the cartridge ?.... and did you need to raise the arm lift cueing bar at all ?
My Audio Technica works with no spacer and sounds great on my RP6 after being professionally setup. See my system info. I got it from 2juki on eBay. Many great reviews here about his service.
I am asking specifically about the Nagaoka MP 500 needing spacers with the RB301 arm on my Rega P3-24.
