recommended 24v PS for Naim phono stage?

Hi,

I purchased a used Stageline N Naim phono stage. I don't have other Naim gear or a PS for it. What's a good 24v PS to get the best out of the Stageline?

After opening the unit, I saw 10 of ZTX384/ZTX214 transistors per channel.

Some options are:
Jung/Didden Superreg
TeddyReg
Classic PS, similar to Naim designs.
and finally: Should I use a dual mono PS since the Stageine has a pair of "+ V in" on the the DIN connector? Is this separate power sources for each channel?

Thanks,
Herman
