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