Primaluna Diaglogue Premium Preamp Owners

Found lots of info regarding the older PL preamps but not a whole lot about the newer ones.

How have the stock factory tubes held up?
Did rolling different rectifiers change much?
Did you change just the middle two 12AU7 tubes or all six to the same make/model?
Have you changed the factory power cable?

Cheers.

Like Dsper, I replaced the first tubes with NOS Mullards, made a nice improvement in the midrange.

As for caps teh stock caps are SCRs from Solen. Many options aftermarket are available. I used the Jensen Copper Foil caps which makes the music sound much more organic than any other film caps I have tried.
