I presume you are auditioning speakers. A consumer can have control over a number of things. The products compared should be listened to at the same levels, as very often a small level difference is interpreted as a quality difference (detail, image, etc.). As well, the speakers should be set up in a reasonable manner, usually not too close the the walls. The bass to lower midrange will most probably not sound the same as at home, but most the room affects the speaker most below 300-400 Hz, so you should be able to get a good idea of how the speaker sounds.The program material should be something you are familiar with. For consistency, I always include an old Denon Classical Sampler which I have used for many years, and have found a few tracks on it which work well. You want recordings which show differences between speakers and having some on a sampler CD can make things easier for everyone. You could burn your own, too. For preliminary auditions, I use full orchestra with massed strings, male and female vocals, mixed chorus, and piano. This can be done in a relatively short time and not many speakers make it through them unscathed. Those that do I subject to a variety of other recordings, possibly at a subsequent audition. When I have narrowed down the list, I want a home trial (a written return period will do, if necessary).
Now, for your own satisfaction, you may want to audition CDPs, preamps, and amplifiers. Level matching may be difficult, but usually I have found that I can get two competing solid state amplifiers to sound about the same simply by adjusting their volume controls, but a measured level match would be better. But anyway, auditioning an amplifier will enable you to be sure it can drive your speakers properly.
