Rega P3-24: Is the upgrade power supply worth it?

Yes. One of the best, most cost effective ugrades you can do.

In a word.....YES. In my room, with my system, and to my ears, the addition of the TT-PSU has allowed me to hear a definite improvement in the sound of music. I am now enjoying a deeper soundstage, a greater sense of pace and rhythm, a slightly tighter bass response, and an overall "it sounds better" type of feeling.

I had my Rega P3-24/Exact 2 set-up since December 2008, and I added the TT-PSU this past Autumn. IMHO, it has been a very worthwhile purchase. Do a search on these forums, and you'll find lots of good information. Also, if you "google" Rega TT-PSU, you'll find some good reviews. Good Luck, and Happy Listening !!
