Replacement tube for Peachtree Audio Decco?

for better or worse, a speaker change is going to have a much greater effect.

Email Dave or Richard at peachtree/signalpath for tube recommendations.

I like my speakers, very much actually, I am using the Swan D2.1SE monitors. Actually I am happy with the sound of the Decco, but I keep hearing that better tubes mean better sound, and most say the you can do better than the stock Chinese tube.
