You people really are fountains of knowledge.  Thanks so much for 
sharing all that with me.  Would it be a fair assumption that I should 
be using a USB audio device that has mixer controls so I can adjust for 
these different line volumes?

FTR, the manual for my amp doesn't specify the line out volume-only says 
150mV/1.6kOhms

Thanks, Tim :-)
