High Fidelity Test Report Snippet, 1977 Edition. PP 65-66
"Lab tests performed by the CBS Technology Center turned up some unusually impressive numbers and show the rating of this amplifier to be very conservative. Total harmonic distortion is rated at 0.05%, a recent upgrading from Marantz's original 0.1% spec; the worst the lab could squeeze out while remaining within rated power was just under 0.02% - and that was at 20kHz. Intermodulation (rated at 0.1%) remains far lower to well beyond rated power for 4-, 8-, and 16-ohm loads and shows virtually no tendency to rise at low power levels."
