I just landed a WA22 Gen 1 and have been messing around with it for about a week. It is quite a step up from my Gen 1 WA2 (which is also stellar). Ordered a fresh pair of HD650 directly from Sennheiser and it's just unbelievable. Had the original HD800 but hated it and sold it long ago, love the 600 and 650 way better.
I am using the XLR 4 pin out but never tried separate 3 pin XLR's so ordered a cable to try it out. Been through quite a few tubes and most all of them sound good. I've been stuck on the Sovtek NOS rectifier (5R4GY with USA mark) with spring filaments (can't find any info on them or find extra sets anywhere). Really awesome tube. Raytheon 6SN7WGT drivers, and Sylvania GB 6080 power. Really incredible combo, great clarity, tight and punchy bass, holographic. All of the right cliches apply here.
