Nav - send that nurse to my house and my wife will be pissed!
Sounds like you're the guy to know if I decide to upgrade the PL 400. She's driving my 808's very nicely now but I think the speakers deserve more.
Hope you don't mind me asking questions in the future? I don't mind working on my gear myself but have limited electronic knowledge and beginner soldering skills. What I've seen about the WO upgrades they give pretty good instructions (I can read), I just have to muster up the courage to attempt it.
Thanks for the interest. Think I'm gonna enjoy this ride.
