Bon, in my opinion, there are two definitions of "air" that are bandied about on Audiogon. One means blackness, or silence, between instruments and vocalists. The other definition of "air" means a sense of the recording venue: ambience, echo, reverberation...those aural cues that give the listener a sense of place.
Which of these two definitions are you using in your evaluation of the RealityCheckCD?
