The Chinese Treasure’s are clearly a step above the very good Gold Lions. I have replace all my fine NOS KT88’s, 6SN7’s, and EL84’s with Treasures and found enhancement with all my gear, decidedly so. I am having no longevity issues personally. I forget the price difference between the GL’s and Treasures, but if the coin of the realm is a limitation, the GL’s are fantastic and durable.
