    Need a Decent Amp Suggestion

    My setup is:   Rega RP1 >> CA Azur 640P >> AMP >> BeyerDynamic DT770's.   I need a good amp for around $150-$400.    Would be nice if it supported more than just headphone and could do speakers too (as I want to get a good pair of speakers down the road).

    Should I Choose WA2 or WA6-SE? (Closed)

    Hello Head-Fiers.  A few months ago I tried asking for help finding an amp but found no replies, so I've been left to my own devices and have lead myself to Woo Audio.  I am trying to plan ahead in my choice of amps, so let me explain myself.  A year ago I purchased a pair of Sennheiser HD650s...

    WA6 has a low frequency hum on the left side, no matter what tubes are in it.

    Switched left and right tubes, replaced rectifier with a totally different model, same result. When the WA6 is initially powered on, there's a loud hum/buzz on the left side, that drops off sharply after a few seconds, but when I turn off the amp, it's noticeable that there was still some hum...
