Gold Lion KT88's Upgrade

Gold Lion are very nice, balanced sounding KT88's. JJ's are very similar sounding IMO. Two other options are the Black Treasures which I don't think would be a great match in the Mc because they're relaxed sounding, could be too much of a good thing. The Psvane's I'd think would be an excellent match in the Mc because they're a bit more lively.

I purchased some GLs KT88 from Jim and have them burning-in, very musical but need more time for them to hit their sweet-spot before doing any comparison between my stock Shuguang KT88 SC...

Get a quad of GE 6550 and you'll never even think about the Gold Lions. I currently have a matched quad of Gold Lions KT88 purchased from Jim Mc Shane sleeping in my drawer for the past year or more... replaced by GE's. They are that good

Facten,

Is Jtrelja still selling these tubes? Can't find him under that name.

Thanks,

Trelja is his working name here on the Gon No first initial J. You might want to search for him here or at his old web site Ultraviolet Audio.
I don't know if he is still selling tubes.
