I've tried the Rega Fono on the P5. There are others that sound significantly better, more dynamic, open and live-sounding. The Fono is probably good on the P1 or P2. The P5 deserves a better phono stage as it allows the quality of a superior phono stage to shine through. I'm still looking for one myself without breaking the bank. You might want to look at the Dynavector P75Mk2 considering you have the Dynavector cart.
