when looking at that api output transformer thread, got me thinking about a general idea that is likely too general to have an answer, but figured Id ask just to remind everyone here how green my grass is...
When looking at a 2520, designed to push a 75 ohm load, but able to handle a 600 ohm load with decreased headroom, can this state of affairs (driving lower the imedance the better) for some opamps? Is there some very basic and general theory that can be layed out in kindergarden terms for me? I had thought that the higher the bridging impedance, the better, what are the circumstances upon which a 2520 likes driving a 75 ohm load better than a 10K load?
this is very general I know, but...
