PrimaLuna ProLogue One versus Two

I own the prologue one. Which I love. These words are from Kevin Deal @ Upscale audio in an email he sent me:
"In a nutshell, the ProLogue Two will have a little more dynamic and punch than the One. It will also have a smidge more clarity and detail, due to the upgraded capacitors and fast-recovery diodes. The ProLogue One is smoother sounding. "
Hope this helps.

The Prologue One is my first foray into tubes. I'm not even sure what tube rolling is.

Using Dunlavy SC-III's with incredible results.

Fellow Primaluna owners. I have the PL One. I happened to win a audiophile aps 700 ac power regenerator. I wasn't expecting much but I figured, what the heck, it's free, and it probably can't hurt having clean power so I hooked it up. After a day of use I am very impressed. The bass in particular is much more dynamic and with more punch. It is now very close to the bass I was getting out of the Krell integrated I was using. The highs sound more natural without any shimmer. Overall it's a very nice improvement over what I felt was pretty awesome sound from my system. It's a pretty expensive item, given the cost of the PL's, but my experience with this type of product has been very positive in case any one else here ever wondered about these things.

Mikemarv, the audiophile aps did not improve the sound anywhere near what a component change would do. It improved the bass more than I thought possible, other than that the improvements were subtle. Overall it did make my system more satisfying to listen to however if I spent $2200 on this I think I would feel disappointed. But that is a personal call. The money could be spent on more music or a major upgrade for a primary component. I have both the PL and Arcam plugged into it. The folks at audiophile aps said there is no need for separation of digital and analog components with their product. From the little bit of testing I did I would say they were correct.
