Whew, I've been having a lot of questions lately... Thanks for all the help...
I've been playing with terminating the output of my various mic preamps with different values (600 ohms and up), and doing frequency sweeps and listening to music. Pretty drastic differences in some cases. I've found that a lot of my "vintage" gear that likes to see a 600ohm load often benefits in the high end (often extending the hi roll off point without causing a noticeable bump) with a 1K termination driving a 10K A/D converter input. I got the thinking that 1K (or slightly higher) would be a great value to terminate 600ohm output gear, so that interfacing with both 600 and more modern high Z loads wouldn't cause too drastic of freq. response changes.
My question I suppose is, is this "acceptable" to do? Are ouputs of commercial units generally terminated for "best" compromise frequency response?
