Gold Lion KT88's Upgrade

In my only outing with 88s I preferred the Black Treasures over the Good Lions but could fully understand why someone else would or could prefer the Good Lions as their signatures were of a different flavor. Enjoy the music

Agree with you I like the Black Treasurer sound much better

If agree with the member whose suggested the GE 6550s. If you can swing the cost. I recently bought a fairly decent number of the Russian Gold Lion KTs and wasnt impressed with the factory test readings in terms of consistency. Not huge numbers but about 30 to 40 of the 88s and the 77s. Should note that none were bad. 

I recently retubed my MC75 mono amps and used a matched quad of the Gold Lion's with great results. I can recommend them.
