Envelopment can be reproduced with few channels, not hundreds

Evidence

Here it is necessary to emphasize that reflections occurring in small rooms cannot alone generate a sense of true envelopment. Envelopment requires delays (more than about 80 ms) that can only be supplied by recorded signals reproduced through multiple loudspeakers. Additional room reflections of those greatly delayed signals may enhance the impression, but the initial delay and the appropriate directions must be provided in the recorded sound and an arrangement of playback loudspeakers. — , Toole, Floyd E - Sound reproduction-…, 1694 (#contradicts, via linked claim)
