Woe mule,
I may/maynot be missing something here.
According to what you’ve written
"Preamp and amp are using Lumley Reference",
which means you’re more than likely using the Ray Lumley Pv1 reference pre-amp.
Now to the best of my knowledge the PV1 had a pretty good phonostage in it (unless yours was line only), so the question arises: why are you using EAR 834P phonostage? And B: why are you thinking of blowing more cash (+ interconnects) on a PS audio Stellar phonostage?
If anything, re-cap the PV1, get some new tubes and with the money you save on another phonostage, consider a better M.I cartridge, such as a Soundsmith Aida MkII. Same price as the Lyra, has a lower mass than a MM, and with 2.8mV’s of output you’ll be fine with the gain the Lumley Pv1 has.
The other thing I’d like to add is your idea of purchasing the PMC 24’s. DON"T DO IT! Use the money you save towards a pair of FACT 8’s!!! New/or used.The Facts are so far ahead of the Twenties it’s unbelieveable. In another league altogether. In comparison the 24’s are dead/lifeless. I don’t say this lightly! I spent several hours at Altronics in Toronto, and spun several LP’s and the profound difference is real.
As for the Rega table?

Enjoy the music.
