Performance Limits and Ratings
Performance limits are the maximum deviation from
perfection permitted for a Mclntosh instrument. We promise
you that the MX 113 you buy must be capable of perform-
ance at or exceeding these limits or you get your money
back. Mclntosh is the only manufacturer that makes this
guarantee.
