Cantilever OTL quattro elementi - 5 mV @ 3.54 CMV - 10Hz-55kHz - Bobine OFC - versione P-Mount
Associated Equipment: The power amplifier was a Carver TFM-55x controlled by a Carver CT-17 tuner/pre-amplifier and, alternately, a Carver CT-26 tuner/pre-amplifier. Speakers were Mach 1 M-twos with two NHT model SW3 subwoofers driven by an NHT SA-3 amplifier. The turntable was a Dual CS5000, and a Shure V15-V cartridge served as a reference point. Listening: I used the white noise cut of the Realistic HiFi/Stereo Review Model 211 Test Record (Catalog No. 50-1001) to compare frequency response to the Grado and Shure cartridges. I placed the microphone 1 in. front of the left speaker, on the tweeter centerline of the Mach One's, but with both left and right speakers (satellite and subwoofers) running. Frequency responses were similar between the cartridges, and close to flat. The Grado had just a slightly higher output at the same volume setting. Output was the same from both channels.
