How to Match Levels?

I want to do some testing of digital sources with my Stax Omega phones, but I have no idea how to properly match the levels to within the golden .1db goal. I have heard that a sound meter (a la Radioshack) won't cut it.. why not? If I place the phones properly and place the mic between the phones and play 1 KHZ tone or something, how close will I be getting to properly matched levels. After years of buying gear based on sound and opinions, I honestly want to test some things now, and am surprised at how little info is available...

Any help?

Well, I am ideally trying to match the levels on the source devices (cd players, dacs). But I have no way of attenuating their signals so they are putting out the same voltage. All I want to do is to be able to A/B source components at the same levels. However, the pin config for Stax phones is funky, and has some very high voltages coming through it..

So, if I simply want to A/B source components and get the volumes equal.. what do I do?
