Cartridge Upgrade - Nagaoka or Goldring


Current set up:
Rega P2, Goldring E3, Rogue RP-1(built in phono), Rogue ST100, Martin Logan Montis.
I love the sound I get now, but looking to step up from the E3. Has anyone compared the Goldring E3 to 1042 and/or Nagaoka MP200? How about Goldring Eroica? 
Would the Nagaoka work on the P2?Would a difference be significant with any of these cartridges over the E3 using a built in phono in my Rogue preamp?

I listen to all kinds of music...from classical to heavy metal.

Thanks in advance!

I've been using Goldring 1042 for years with the Nottingham Spacedeck/Spacearm and have no plans to replace it. Bought it from analogueseduction.net from the UK. Sounds very good with all kinds of music that I listen to. Can't speak of classical music, but for jazzrock, acoustic music and vocals I find it satisfactory or better. It is very alive but does not 'throw' the sound at you, very dynamic. Well, so is the Nottingham turntable. Nagaoka MP500 might be more refined but I like the sound to have some 'edge and bite'. Yes, upgrading your table is a good idea indeed.
Those pickerings are very nice.  I never see them NOS anymore.

My Pickering XSV/4000 cartridge is still sealed, the rest of the samples are opened. Still hunting for them, NOS are very rare indeed

I think 1042 is very good match for Rega tonearm. Great Cart.
I have E3 on my Technics 1042gr and I'm very, very impressed !!!
