Hi Bill,What's going on with the Foreplay? Sounds like it may be being retired! Anyway, I just thought I'd mention that in my messing around with my EL-84 amp I found that adding a final stage of PS filtering using a 4uF GE oil cap(actually two, in pseudo dual mono config. ala VoltSecond) really opened up the music in an incredible way. Tried chokes as well but the oil really does it. I imagine the Ella is too new to begin ripping appart but thought I'd mention this for the next time you are possessed with the insatiable desire to improve things by your own hand. Tomorrow, maybe?
