Rega TT PSU..... one or two buttons ?

I'm thinking of buying the TT PSU as an upgrade for my Rega P3-24/Exact 2 front end. I've seen different photos on the web, and it seems as if there are two versions of this unit. One has one button (33 1/3 - 45 RPM), and the other has two buttons (Power and 33 1/3 - 45 RPM). Is there a difference ? Are there actually two versions of the TT PSU available ?
Also, what are the thoughts from those of you who have the TT PSU ? Is it a significant upgrade ? Thanks a lot.

Newer model has 2 buttons on front. All had 2 buttons. The older TTPSU has the power on the back. And yes, I had one when I had my P3/24 and it made a pretty substantial difference. Surprising really, Will depend on the resolution of the rest of your system, but do a web search you'll see people comments on this upgrade.

I have a P5 and the addition of the TT PSU improves the sound. To me, it is not substantial, but noticeable. I guess it is worth it if you can get one used. Again, every bit of improvement helps.

Cjnolan, I am having a tough time deciding between the basic P3-24 and one with the TT PSU and would appreciate if you can briefly describe what sort of differences have you heard. I don't mind if the improvements were subtle as long as they are noticeable but it would be disconcerting if I cannot hear any difference with the TT PSU on board.

On a separate matter, how would the P3-24 with TT PSU compare to the basic P5 without the TT PSU?
