I have the PL Dialogue Premium integrated . I don't know how much of a difference that would make in the evaluation .
In place of the stock 12AU7's you might try some RCA clear tops . I liked these quite a bit for warmth , clarity , definition and musicality . If these RCA's are to your liking , then try some Amprex 7316's . They are like the RCA's on steroids but more expensive . The 7316's are what I settled on after trying most of the others .
