Woo Audio WEE - Issues! [ALSO POSTED IN THE MAIN STAX THREAD]
I haven't contributed much here despite lurking for a long time, but thought it would be useful to share my WOO experiences and to ask for any help the forum could give. I paid for a WEE with normal and pro bias sockets back in December. The first unit I received had something seriously wrong and buzzed loudly, so it went back across the Atlantic (I'm in the UK) and was 'repaired'. The repaired unit still hummed (but much more quietly) and following an exchange with Jack eventually went back a second time, when I was told Woo could detect no fault. It's now finally back in the UK and the issue is as follows:
I have no hum from any other equipment (Stax 4070, 407, and original Lambda, SRM-T1S and SRD 7 Mk2)
Woo WEE hums from pro bias port (loudest on 407, and only slightly audible on the less sensitive 4070)
Woo WEE hums when connected to sources and when running completely by itself
Hum is not volume dependent and is a harmonic of 50Hz power
Hum only happens when the bias circuit is on
I have tried the unit in three different locations and think it may have been quieter in one, so do wonder whether there is a mains issue to which it is super sensitive...
Woo will not help any further at this point (and have treated me like some sort of idiot, which doesn't seem very characteristic). I am a professional musician with 25+ years of recording experience and have never had a problem with my audio gear...
Any advice would be very welcome!
