Cart, table, arm, stage integration on a budget...

I'm currently using a Pro-Ject 2.9 Wood Classic table with the Pro-Ject 9 arm and an inexpensive Ortofon Super OM10 cart, and that runs through the phono stage on a Musical Fidelity X-150. Honestly, it sounds pretty darn good! But, I'd like to pull a little more out of all that yummy vinyl.

At the top end of my budget would probably be a Rega P5 or the new Pro-Ject 2 Xperience with the carbon fiber arm with either a Rega cart, or Sumiko Blue Point Special. A CLearaudio Emotion/Satisfy, and a Music Hall MMF-7 are in there as well. If a Rega P3 would add a marked improvement, I'd be happy with the savings!

At what point am I throwing money into the wind using the MF phono stage? Or, getting too much cart for the arm? Or....

Thanks,

Chip
