Dear community, my name is Iván.

I'm from Chile. I appreciate accepting my participation here.
I have a question for you. I recently bought an Eastern Electric Minimax Supreme DAC. I want to get the best performance, for this reason, I want to upgrade the tube. Some of you could suggest me an adequate tube?
I have been using a Chord Qute Ex for a long time. I prefer open, detailed, realistic sound, with a wealth of details ...
I will appreciate your help.

Regards
pd: sorry for my bad english!
