Performance Limits and Ratings

PERFORMANCE LIMITS
Performance limits are the maximum deviation
from perfection permitted for a Mclntosh instru-
ment. We promise you that when you purchase a
new C 33 from a Mclntosh franchised dealer, it will
be capable of or can be made capable of perfor-
mance at or exceeding these limits or you can return
the unit and get your money back. Mclntosh is the
only manufacturer that makes this statement.
