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.

Thanks for everyone's feedback.

I have not been a fan of the stock tubes mated to my XA30.5 power amp. The highs are a bit shrill for my liking so I've ordered some 60's Mullards to replace all 6. I don't know what PrimaLuna uses as stock tubes since they're rebranded but I'd rather just get them out of there. 

Has anyone replaced any caps in their unit? Space seems a bit tight but I can't find anything about DuRoch other than PrimaLuna uses them. I assume they're also rebranded something but in the world of caps I can't see them ranking very well.

All the parts of "premium" compared to most of the stock crap that's out there but in the DIY world most of them are moderate at best. The build quality of the amp is top-notch and overall I really enjoy the sound I'm getting. Don't know how it compares to a 6SN7 preamp, maybe one day I'll get one to find out!
The DuRoch caps are the SCR from Solen in the dialogue premium preamp? 

Which caps did you replace with the Jensens? They seem much bigger than the stock Mundorf EVO silver/gold caps.
