Primaluna - Rolling pre tubes question...

If the Cifte's take you in the right direction , you may want to try them in the driver position also . The two front/middle tubes control the input section and the two back/outside tubes control the driver section .
Some people will experiment further with different tubes in each section to further tailor the sound . There are many possibilities !
Have fun and let us know how it goes .

One week with the Cifte 12AU7s in the front position, and PL stock tubes in the rear. I'm assuming they may still be settling in...probably 40 hours or so on them.
I'm hearing clarity across all frequencies - not harsh - more like we've turned the light up in the room and the back corners are illuminated. Really nice.

With some recordings, a lack of humidity is revealed...perhaps a bit papery at times.

Would a Mullard or other similar type in the rear position balance the sound? Mechans -You mentioned the British tubes?

Take for instance, a well recorded drum kit...I want all that air and resonance, and maybe a touch of fuzz on the kick drum...More tennis ball than rubber ball.

I'm missing the luscious mids and upper bass.

Yes there are classically warm British tubes like the Mullard ECC82, the Philips Miniwatt, Mazda,and even Valvo (which is as likely to be German so be careful, etch code is your ally) and the Mullard Mil Spec 4003.Another British tube that glides under the radar that is the more neutral sub made by Brimar the 13D5. I am sure you can find Mullards to try., but if you didn't like the reissue Gold Lions not sure you would like these either. Did you try the small Gold Lions? I forget but does the treasure series include some of the pre amp tubes?

Hi - I have a Dialogue 2, and I had a 12au7 go out on me, so I bought a new pair, and they were not as good as the stock tubes were - the stock au7s in the PrimaLuna amps are pretty good. Next time, I will be buying them, as they were also less expensive than the ones I did try. I have not done a ton of tube rolling, but like many others here, I prefer the sound of EL34s to the KT88s in the Dialogue 2.

Learsfool, I had the same experience, after rolling all of the tubes in my monoblocks; I quickly put the 12au7's back in.
