Basically this is a thread for people to request measurements from people that have the ability and equipment. Just whenever anyone feels generous or is bored. If anyone knows a link of a requested measurement that has already been done then this would also be a good place to post it. I'll start things by saying I'd like to see some measurements of basic headphone outputs like for laptops from Dell or Apple. Mainly because while headphone amps publish quite a few specs, headphone outputs publish almost none so I can't really get a good comparison.
