“It’s not taking that long for break-in – already it sounds like a whole different system – denser, richer, weighty but still focused and clear. Best $400 I ever spent! Thanks for the good advice. “
Here is what reviewer Mark Wheeler said about these globe shaped tubes:
“If your 6SN7’s are on show and there is space for them, there is every reason, sonic and aesthetic, to install the Shuguang Globe 6SN7-SE. In a high resolution system, especially of the low-to-no negative-feedback persuasion, these Shuguang globe 6SN7-SE bottles are the state of the new-wave-of-valve-production (NWOVP). So far Shuguang have not put a foot wrong and we can hope they continue to innovate new versions of those classic valves we all love.” Read the full review here.

Just recieved two pairs of CV181-Z ‘A’ Tubes from Grant Fidelity. They came in nice boxes, way over packed, and quick. I then tested them on my own Amplitrex 1000 tube tester, and, folks, these are the most closely matched tubes I have ever bought.
