Rega P25-best upgrade


I'm considering two different directions, one which is not exclusive of the other as it too can be done at a later date. Therefore, I'm wondering which will give me the biggest bang for my bucks and why?
1. Add the 3 Groovetracer upgrades: Subplatter, platter and counterweight; or
2. Add a new Cartridge. Currently running Dynavector 10x5 and considering Dynavector 17D3, Sumiko Blackbird or Clearaudio Virtuoso Wood (with the Dynavector 20XL or XH in the back of my mind).

The reason I might consider using a High output cartridge over a Low output is because I record each album I play to CD so I don't want to have to crank the volume to get the CD up to the gain point of regular CD's. That is, even with the Medium output 10x5 I still need 60 db of gain (and that's the max) and that is perfect for recording. Not sure how a low output cartridge would do as I've never used one. Associated relevant equipment Rega P25, Bel Canto Pre2p and M-Audio 24/96 sound card. Let me hear what the experts have to say...I certainly am not one. Thanks.

Winoguy17, you may have been kidding, but I feel the need to stick up for Audiofeil. Dealers often get a bad rap, but there's nothing wrong with selling equipment you believe in. He also contributes a great deal to the forums. If you look through his answers, you'll see that he's a wealth of knowledge and willing to share what he knows. I just wanted to point these things out.

That said, I'd also like to know what tonearm he recommends.
Agree Mingles, its just worth noting that the original poster never even said what arm he IS using (assume a P6?). Also,as you noted , it would be good to make a specific recommendation, not just an all encompassing "change the arm "
