Prima Luna Dialogue series, is it worth the money?

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.

prima luna has announced that they support KT-120 in all their KT-88 compatible amps now. Got mine yesterday and after a few hours of rocky break in they proved wonderful for bass slam and dynamic openness. Don't think I'm putting the KT-88's back in anytime soon

I'm a former Hollywood film composer and sound mixer, and the Dialogue Premium fitted with matched Tung Sol KT120's, coupled with the Prima Luna Classic Tube CD player, driving a pair of Martin Logan Electrostatic hybrids, is the equal to the best 2 channel analog system I've ever heard (Krell-Apogee) at less than 1/4 the cost. I have two SVS 13" Ultra sealed Subwoofers hooked up thru the Dialogue Sub out, crossing over at 40hz,, and the combo was absolutely gripping. Tremendous transient detail, but with a creamy liquid center. I literally can't wait to wake up, turn the Prima Luna gear on, let it warm up for 15 minutes over the paper and a cup of coffee, and spend the morning re-discovering my CD collection for the first time.... 5 stars across the board!
