"it's a possibility that the computer system wasn't fully performing"
Could be, but I'm finding my QB-9 more or less "immune" from computer-side tweaks. I suspect the asynchronous USB operation and galvanic isolation make it so that futzing with the PC is not neccessary to get great sound.
"The qb9 was no where near the C5"
My guess is that the QB-9 was not fully broken in. On another site, Charles Hansen opined that the C-5 and QB-9 are neck-and-neck sonically.
