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
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.
I had Gold lion kt88s in my Rogue Audio m180s, and over time four of them blew up in my amp, one time so bad it took part of my circuit board with it. I liked the sound but will never put these in my amps again. I also ran my amps with Gold lion kt77s without problems, and use Gold lion 12au7s with good results. I dont know if my Rogues drive the tubes harder than the Mac gear, hence the high failure rate.
