The real purpose is to isolate the room effects. as in reverbration, delay etc, from the interaction of the same space with an instrument or voice. Take a piano for example; in the anechoic chamber you will only record the sound of the piano and when you play it back you will get the room effects and no interaction. When you play the instrument you will get both. I am wondering how much of the "realism" comes from the interaction between the source and the space. If there is no such thing then you would not be able to differentiate the recording of the recording in the acoustic space vs the recording of the real instrument in the same space. The secondary recording is the re just to make things a lot more comfortable, no need to get acousticly transparent curtains and a bunch of other things to make the test reliable, you can just give the recordings to a large number of people and ask them the simple task to identify which one of the two recordings sounds more real. Also if you use a high quality digital player piano, you could take several takes and subtract the anechoic recording from the acoustic recordings and see what the actual differences are. On avarage it should be the interaction of the space with the instrument, since both recordings should have the same room effects.
