Prima luna dialogue 2 tube rolling


Hello all,

I would appreciate your input on this. My current set-up is a PL dialogue2 with the stocktubes, Klipsch forte2 w/crites crossover/tweeter/midrange. I enjoy the sound and I’m re discovering my cd’s/lp’s and listen a lot. However, sometimes I would like a bit more warmth in the sound without giving up detail/dynamics.

So after some reading on the internet it didn;t took long till I’d tried a set of Tung Sol 12ax7’s 1st impression was wow, more air, larger better focussed image, more detailed, perhaps a tad warmer. Unfortunately it also added a bright harsh tone to the top end on a lot of records which was very unpleasant to listen to so for now I’ve put the stock 12ax7’s back. Shame, without the harshness it would be a step up.

Sometime ago they was a tread by forum member Dramapsycho concerning the PL dialogue, ending up with Sylvania 6l6’s tubes + some Telefunken and solve a harshness problem. I’m now considering SED 6l6 tubes as they are described as the best alternative to NOS several times and they’re not as expensive. Will this in the right direction? Anybody has experience with the SED tubes, of other pre/power tube suggestions ?

I would like to hear you input, thanks

I think you can use EL34 in this. I have the PL2 and the EL34's were a much smoother sound then the kt88's.

try some Mullards in the preamp section if you want some warmth
Yes use the fairly expensive true NOS made in Great Britain Mullards for your 12AX7s. I think it will solve your need for more warmth.
If the Mullards seem too warm to you; try Amperex. Keep in mind; the more transparent/accurate the tube, the more revealing your system will be of poor recordings, and/or any other weak link upstream(ie- a bright or grainy CDP). Also- anything you do to extend/accentuate your highs, will be rendered even more prominantly through your Klipsches.
