The Shuguang and Psvane CV-181's do take some hours to settle in.

I do have Gold Lion KT88s, Black Treasure KT88s, Penta Labs KT88s and Sovtek KT88s that it'll be fun to compare the NOS Tung Sol 6550s to.
The Gold Lion KT77s that everyone seems to love I just can't agree. I've listened to it a fair bit in a few different amps now, and to me its always a bit hard/flat sounding vs other tubes. Even the Gold Lion KT66 sounds better to me. Although the Shuguang KT88 Black Treasure is probably my favorite modern pentode/tetrode tube so far.
