Prima Luna Dialogue series, is it worth the money?

One interesting thing about the tubes - the stock ones are not necessarily low quality. I did replace the KT-88's in my Dialogue 2 with some EH EL-34's, and greatly preferred this. However, I had a stock AU7 go out on me and bought a relatively inexpensive replacement, and these do not sound quite as good as the stock ones did. The AU7's have the least effect on the sound, though. I have never experimented with the AX7's as of yet.

i am using a prologue II with Harbeth PL3s and love it . Did some tube rolling and using Mullard el34s. Power to spare and wonderful mids. The MM phono is fantastic BTW.

Do not replace the AX7's. I replaced all of the tubes, but quickly put the AX7's back in; that was on my Prologue 6.

I have the Prima Luna Prologue premium... reviews on it are pretty accurate... plays best at moderate to loud volumes and a little bass shy at the bottom if you use the integrated pre section. These go away if you use a better pre with the home theater input (pre bypass) and subbing 12AT7 for 12AU7 in front socket does help improve dynamic separation. Reviews on the Dialogue all talk to deeper bass and black space... if you have source and speakers of equal quality I wouldn't hesitate. Do upgrade to NOS tubes and better power tubes... the stock PL tubes are pleasant but a little grainy in sound and not detailed.

Thank you all for the advice. I appreciate it.
