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

Suggestions to call Upscale is a start.

Since Kevin is the distributor and offers tubes, he can suggest something that also won't break the bank. V11 &12 are the biggest influence other than the power tubes.

Perhaps some of the new production are good deals instead of pricier NOS?

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.
