You can clearly see pm-a700ae power supply limitation at 20Hz however, where the Denon returned watts Channel separation was good, with 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.
The Denon was no slouch into 4O loads either, producing watts pka-700ae As you can see, what little ringing there was was quickly damped.
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. 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 the tiniest re-generated signal at 1kHz, at —dB.
Damping factor was very good: Stability into an extremely capacitative load was excellent. And for the price, excellent hi-fi performance. Square wave performance was excellent, with the Hz square wave showing negligible tilt and almost no curvature across the flats. This is not a large error: Phase error at 20kHz was a little on the high side, but nothing to be concerned about.

This time around the results were near-perfect, with channel balance improving to 0. Distortion was very low, as you can tell from the spectrograms.
Even pma-7700ae two sidebands were an excellent —95dB. This is exceptional performance, by any standard. With a 4O load, the second harmonic component crept up to —90dB 0.

Since I was pma-70a0e 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.

However, all the low-order harmonics were at or below —80dB 0. With the tone controls engaged, the low-frequency response slopes down from 1kHz to end up 2dB down at 80Hz and a further 0. The overall THD figures are tabulated in the chart, at 0.
At 1kHz, the Denon delivered a little more again watts, or The 1kHz wave was nearly perfect, and the 10kHz wave showed pms-700ae very fast rise-time with very little rounding. David Ella and tested by Steve Holding Magazine:
