Best tubes for sonic frontiers power 2?

I changed winged Svetlanas for the new Tung-sol 6550's in my Power 3's and they are a much better tube all around. Better low end definition, smoother mids and extended, sweeter treble. A significant upgrade and I was surprised that a variant power tube of the same type would have made such a difference. I am very partial to the KT88's as well as I think they are a little "sweeter" than 6550's, but I never tried them in the Power 3's.

Hi All,

I have an SF Line 2 on the way. I will be using it with a ModWright Oppo and primarily listen to digital media. I also recently purchased a Conrad-Johnson MF2275, so there's that....

I am looking for a 'dark liquid' sound. Not 'warm' or 'bloomy', certainly no glare or blare. A hint 'woody' would be alright. Tightly radiant and/or illuminating would be good.

So what tubes can you all recommend?

Thanks so much for for all of your shared experience.

Best,
b

Shuguang Treasure KT88-Z will give you a ’dark liquid’ sound, although it won’t come cheap!

Black Treasure KT88-z will set you back $110 each at TheTubeStore.
