If the choice was mine I would sell the Rega and put the money towards a used Exemplar 3910 and some good tubes (since the server is not set in stone) for it. Although I have not heard the modified Rega, I would avoid the RAM mods.
Has Anyone Tried RAM'S Rega Saturn Mod?
If so, please tell me what you think. Any feedback would help purchasing decision. Specifically, sell my Saturn and use funds towards purchase of $5-6K Exemplar Music Server/Dac or go with the RAM mod. I know these are somewhat different animals but I like playing CDs and would probably just use the Exemplar to play my collection-I put little stock in a server's convenience over gettin'and poppin' a CD, and much stock in how my CD collection sounds.(Also, the roughly $2K+ extra for the Exemplar is worth $2K+)
