I located this thread while researching carts as well, and am a relative noob to the "game". To clarify DSJR, are you using the Bronze stylus in the Blue cart body? As I understand, (per Ortofon), they are two different animals due to different internals. One cart body for Red/Blue, and then a different cart body for the Bronze/Black. So you might get an even better sound out of the Bronze with the proper body designed for it? Sorry, otherwise, if I misunderstood your statement.
Personally, I'm upgrading from Pro-Ject RPM-1 Carbon to the Pro-Ject Debut Pro. (I'm getting an amazing deal, otherwise I'd probably go with the Rega P3 at twice the price). I currently have the 2M Blue Stylus, (from my RPM-1), which, (according to reports), will run on the Pick-It Pro cart, since it's built on the 2M Red platform, and I will probably keep that for a bit, until I'm ready for my next upgrade. My deck is/will be plugged in to Rega Elex-R with Goldenear Triton 3's. I like the combo I have, but like many others, I'm on the journey of finding the best possible sound for the least amount of money. Thanks so much for everybody's insight!
