My only, somewhat less than engineering level thoughts were that some of
the fidelity on the reverb and delay tails might be enhanced with a
little additional fidelity. I use decent quality live speakers at
reasonable non ear splitting levels and generally keep them close enough
to maintain a stereo image.  Again, I don't want to spur the argument
that "Only my Dog can hear that damn noise!" :) 

My only real concern here was with my new box. I figured it should run
this no problemo on the 2.4 kernel with Xruns. I read the other
responses from Jack and co (thanks) and need to take a closer look at
tweaking my box for optimum performance.
