Cartridge Upgrade for Rega P-25 Table


I am currently using a Benz-Micro Mc 20 E 2 cartridge.

The rest of my system is
Harbeth Compact 7 ES2 or Proac Response 2
Quad 99/909 or Aronov 960i
Fosgate Phono Preamp

No price range, but I do not want to upgrade the TT right now.

I listen mostly to folk music and jazz with some occasional classic rock thrown in the mix.

I would appreciate input and suggestions on this. Thanks.

I have not upgraded the P-25 at all. I will look into the Cardas Blocks and arm rewiring. Based on the numbers below I will have $1349 (479+870) of upgrade plus trade value in the P-25.

For another $250 I can buy a used VPI Scoutmaster currently on Audiogon. Would that be a better decision?

175 Rewiring (Cardas)
269 Tonearm Cable (Cardas)
35 Myrtlewood Blocks (Cardas)

870 Audiogn BB Value for P-25

Thanks for your thoughts and ideas as I work through this.
I just bought a used Rega Planar 25 and intend to install a Sumiko Blue Point Special Evolution III MC cartridge. I've heard good things about this pairing - Rega and Sumiko. I would be interested to hear any other comments about this combination. By the way, I really like the look of the Rega. It's replacing an entry-level Pro-Ject Debut III turntable with Ortofon OM40 MM stylus. Actually, that turntable sounds great - but I prefer the esthetics of the Rega much better. I also ordered the GrooveTracer Reference Subplatter which should make a big difference in sound quality.
For $1350 plus your Rega P25 you should have enough to buy a VPI Classic - new TT and better arm or Scout II.
Alternately the cheapest upgrade for the P25 would be Rega power supply and groovetracer bearing/platter which would yield significant improvements.
I used a Glider on the 25 that I owned and enjoyed for few years. Benz carts are good choices for the Rega arms.
