Craig, your room and set-up is very similiar to mine. I'm 1 foot shorter, (always behind the big guys) I have been playing around with different powercords and footers lately. Each time I do anything the presentation changes. The past 2 weeks my system has been perfect!!!!! So in the true audiophile manner I had to try a different cone on my tube pre-amp. I lost the magic that fast. So I put the others back, but I cann't quite find the same point they hit the pre-amps bottom plate. It's close but not quite, so I came out to play computer. The point is, even the finest adjustment on a high resolution system like we both share will alter the presentation. Speaker placement we all are aware of, location is critical to success. It's the tweeks that create the magic, not a new amp. Keep trying suttle alterations, maybe go back to a base point, old powercord, new tubes or whatever. I'm sure it's as suttle as a cone moving 4mm. Good luck, keep us posted. Your continuing the high value of this post with your input. J.D.
