Performance Limits 

Performance Limits 

Performance limits are the  m a x i m u m deviation from 
perfection permitted for a  M c i n t o s h instrument. We 
promise you that when you purchase a new C 504 

from a  M c i n t o s h Franchised dealer it will be capable 
of performance at or exceeding these limits or you 
can return the unit and get your money back.
