Happy to help.
Well, I've never been known for my patience. Going to go ahead and sell my WA7 WA7tp to have cash on hand to get the WA8 instead of waiting for the upgrade. Honestly, I am glad there is no tube rolling for the WA8 LOL.
It is a power supply upgrade. It replaces the SMPS that came with the WA7 with a tube-based power supply. It is a significant upgrade that is well worth considering.
yes... agree it should be a proper switch or better yet just turn on when the WA7 volume knob is turned above 0.
12 months now no problem
Bought 2 pair but still on the first set
