Here is a simple initial test before you go get duplicates. A test disc is needed though, with either pink noise or a few frequency bands like 1khz, 100hz and perhaps a 10khz tone, if no pink noise is available. You also need an spl meter,RS has an analog meter, although this is not accurate enough to check the level of the two player to match, it will give you an indication of gross level differences. A tripod would also help to hold the meter stady and ina constant place. Play the test disk with bot players and check the level at the listening place. In a real test, one would use a volt meter to check at the speakers to 1% of voltage with both player. That gives the desired .1db level match but that is beyond the call of duty for your curiosity.
The other problem you will have with multiple discs is how will you synchronize the two so you cannot get a clue which disc is which by one being a bit ahead/behind the other, if you switch rapidly.
With this initial test of level, if they match, do a ten trial yesy on your wife, randomly played in the two players, without her knowledge which is which, and let her write down which player she thinks is playing. Correct the answer sheet after the ten trials, not after each trial. You need 9 correct answers.
