Every channel in a multichannel setup must perform well as a solo monophonic source

Evidence

In summary, while it is undeniable that good stereo and multichannel recordings are more entertaining than monophonic versions, it is an inconvenient truth that monophonic listening provides circumstances in which the strongest perceptual differentiation of sound quality occurs. If the purpose of a listening test is to evaluate the intrinsic sound quality from loudspeakers, listen in mono. For pleasure, or to impress someone, listen in stereo or multichannel modes. — , Toole, Floyd E - Sound reproduction-…, 236 (#corroborates, via linked claim)
