How to level match when comparing components?


Simple question-

When you are trying to compare components, say two CD players, it is often difficult to evaluate them effectively unless you can level match the volume levels pretty closely while A-B'ing them back and forth.

What is the simplest way to do this with a reasonable level of accuracy?

Is there a good pink noise generating test disc out there to help with this?

Stereophile's test discs have pink noise.

You can also download a file from the Internet for free like those available here and other places. If you only have a CD player, download it and rip a CD from the file.

If the object is to listen to music, who needs test equipment. There is no better test equipment than two good ears. You will need to compare the two players one at a time, playing your favorite music, in your listening room.
