Slowhand, the tubes have quiet down a lot since the first night. The noise was probably also in part due to the regulator tube not being seated properly. The norm setting with volume all the way up now seems to work for me too, thanks.
The soundstage has opened up quite a bit, and lifeless recordings now have a natural presence. I'll report back after 300 hours or so. Hard to imagine it will get better, and I'm still in the first 30 hours/stock tubes.
Also, a thanks to Jazzdude for taking the time to answer my questions when I was going through the purchasing decision. Boy, am I glad I did.
