Primaluna - Rolling pre tubes question...


I'm new to rolling tubes, and have been using the stock 12AU7.
I've a PL Prologue premium integrated with 2 12AU7's per channel. I want to test a new pair(before investing in more), so wondering if front or rear position would best reveal the new tubes character?

Thanks,
Darren

Thanks Kevin for the update. Mine isn't near broke in but so far I like the sound with the stock tubes. I ordered KT120s when Kevin shipped the amp but haven't rolled them yet.

The 2 front tubes are all you need to replace. They have the most affect on the sound.

Oh my bad I overlooked the fact it was a preamp only. I've been so focused on my integrated so I am not sure. Have you Googled or searched Audiogon in the meantime?

Maybe what he is saying if you change out 1 pair it changes the sound significantly to the characteristics of that tube and the rest doesn't have quite that much of an effect.  Make sense?
