i'm with Aolmrd1241 try a different preamp Naim gear can tend to be bright and cold imo, I went from a compete Naim system and wasn't listening to music at all to an all tube system and found musical heaven again. just saying....
Primaluna dialogue premium HP tube rolling suggestions to reduce brightness
I have had the dialogue premium hp for about 6 months now, using naim preamp and proac tablette anniversary speakers. I have been noticing some brightness in the high end, and am wondering is I might be able to switch out the tubes to cool it down a bit.
I am running the stock el34 and 12au7. As this is the hp with 8 power tubes, I would rather not switch the el34 for financial reasons, so does anyone have recommendation to change the 12au7 tubes.
I also think the the proacs are contributing to the brightness, but would rather not go speaker shopping again, but have not eliminated that option if you have some ideas

Meiaflask, Recommendations seem to be all over the place. Whatever your ears end up liking, the PL DP preamp would be the optimal setup. With that in mind, the suggestions of NOS RCA,GE,Raytheon. .. American tubes instead of the Euro/Brit tubes have made my PL HP sing like a VERY expensive amp. IME, a decent(not necessarily $$) also add to refining these great amps. With a little searching, you can find 2 decent US tubes for the price of 1 popular Euro/Brit tube. |
leotis107 posts05-20-2017 1:28pmHey George,Yeah for a tube amp, their not very stable in ultralinear mode as JA of Stereophile found when doing his bench tests measurements, and Art Dudley heard. No amount of tube rolling will cure this, as it’s circuit/feedback/output transformer related, best to keep it in triode mode for better stablity. Cheers George |
