tube recommendation please

Hi Gte357s

I bought mine new and it comes with the Prima Luna labeled Sino (China) tubes. Those Full Music tubes seem to be no longer available Grant audio suggest the Psvane 12AU7-T. Do you have a SS or tube Amp? I have a stash of tubes I can roll into the Prologue. I tend to like the RCA black plates or the long plates. The RCA 12au7 black plates are pretty lush tubes you may like them. I e mailed Kevin, but haven't recieved a reply. Will let you know when I recieve his e-mail.

Hi.

I just bought a Prologue 3 a little over a week ago. Unfortunately I haven't had as much time to listen as I want to. Kevin said to wait a a few weeks until the pre has had a chance to break in. I am trying to be patient, but have been contemplating tubes to roll. The stock tubes so far seem pretty good. Kevin selects the platinum grade tube for PL line, so they are screened to begin with. I am not sure which tube the x7 or u7 affects the sound more. I think I will shoot him an e mail. The rectifier tube used in the Prologue 3 have a good reliability record, so I am bit reluctant to change that out--but I probably will. The Mullard 5AR4 is expensive, you might want to look at the alternative versions listed in the manual.
If I may ask what is your amp and interconnects and speaker wire. These can greatly influence the sound stage etc.
