David Ella and tested by Steve Holding Magazine: Even the two sidebands were an excellent —95dB. Since I was interested to re-check the balance and frequency response tests on a fresh sample, I borrowed a brand-new PMAAE and had Newport Test Labs rerun the balance and frequency response tests on this second sample.
As you can see, what little ringing there was was quickly damped. You can clearly see the power supply limitation at 20Hz however, where the Denon returned watts The 1kHz wave was nearly perfect, and the 10kHz wave showed a very fast rise-time with very little rounding.
Square wave performance pma-7000ae excellent, with the Hz square wave showing negligible tilt and almost no curvature across the flats. This is not a large error: With the tone controls engaged, the low-frequency response slopes down from 1kHz to end up 2dB down at 80Hz and a further 0.
Channel separation was good, pma7-00ae a best of 79dB at 20Hz, reducing to 72dB at 1kHz and 48dB at 20kHz, however the balance between the left and right channels was very slightly out, with a 1. Distortion was very low, as you can tell from the spectrograms.
Of some significance was the CCIF intermodulation test, which showed two sidebands at 18kHz and 21kHz surrounding the 19kHz and 20kHz test signals but only pmw-700ae tiniest re-generated signal at 1kHz, at —dB. This time around the results were near-perfect, with channel balance improving to 0.
Phase error at 20kHz was a little on the high side, but nothing to be concerned about. And for the price, excellent hi-fi performance.

Damping factor was very good: Stability into an extremely capacitative load was excellent. You can download a pdf of the original magazine pages on which this review pma-700ad published, which includes all the graphs, test result charts, tabulated results and oscillograms mentioned in the test results, by clicking HERE or on the graphic at right. This is exceptional performance, by any standard. Distortion increased at rated output, as would be expected, with the lower-order harmonics increasing in level, and additional, higher-order components appearing above the noise floor.
At 1kHz, the Denon delivered a little more again watts, or However, all the low-order harmonics were at or below —80dB 0. The Denon was no slouch into 4O loads either, producing watts The overall THD figures are tabulated in the chart, at 0.
With a 4O load, the second harmonic component crept up to pma-00ae 0.
