the ultimate form of measuring, were made before the final
design was accepted.
Design Philosophy
The design philosophy incorporated in the MC602 in-

tion must be as linear as possible prior to the use of nega-
tive feedback. McIntosh engineers know how to properly
design negative feedback circuits so they contribute to the
extremely low distortion performance expected from a
McIntosh amplifier. The typical McIntosh owner would
never accept the approximately 100 times higher distortion
of many non-feedback designs.
Double Balanced Push-Pull design is used from input to
output. Each half of the amplifier contains complimentary
