I'm curious how that NAD would do in a volume level matched blind test with another unknown preamp.
Probably if the competitor also had a dead flat frequency response, low noise, low hum, low distortion, excellent channel separation, low output impedance, etc. it would be a draw.
NAD's more featureful version of the 1300 in June 1988 which included a remote, motor driven volume knob, and a tuner, both part of their upscale "Monitor Series" components at the time [Which I also once owned but lost in a fire.] and found it impressively outperformed its claimed specs:
"The RIAA phono equalization was very accurate, varying only +0.05, -0.2 dB between 20 and 20,000 Hz. The frequency response through a high-level input was flat within ± 0.05 dB from 40 to 20,000 Hz and down 0.3 dB at 20 Hz. . . . The A-weighted noise output was - 113 dB referred to 0.5 volt, one of the lowest figures we have measured from an amplifier.
The 1,000-Hz distortion was about 0.002 percent for outputs up to 2 volts or higher (sufficient to drive any power amplifier to its maximum), and it increased gradually to 0.05 percent at 9 volts, just below clipping. Since no output-voltage rating was supplied with the test sample, we chose 2 volts as a reasonable value. At 2 volts output, the distortion was between 0.002 and 0.003 percent from 20 to 6,000 Hz, and it reached 0.009 percent at 20,000 Hz. The 1-volt readings were slightly lower.
Rarely do we encounter an audio component as thoroughly satisfying as the NAD 1700. Its audio performance was never less than outstanding, and its frequency-response flatness and distortion and noise characteristics approached our measurement limits. In fact, no currently available signal source, including digital recordings, would be degraded in respect to those parameters by the circuits in this impressive product."
