The favored reflection conditions measure as comb filtering yet sound pleasing
Evidence
Comb filtering is often thought to be involved in all delayed sounds. However, a delayed sound arriving from a different horizontal angle than the direct sound is perceived as spaciousness, not comb filtering. It adds to the information about the room. β , Toole, Floyd E - Sound reproduction-β¦, 729 (

In principle, amplitude panning methods create a comb-filter effect in the ear canal signal spectra, since the same sound arrives from both loudspeakers at each ear with a small time difference. This effect is clearly audible in an anechoic chamber, where it produces a notch in the spectrum between frequencies of 1 kHz and 2 kHz. Fortunately, this effect is not present when listening in a normal room, since the room reverberation mitigates the colouring effect largely (Pulkki, 2001a). β Ville Pulkki, Matti Karjalainen, Communication Acoustics- Anβ¦, 1890 (
