However, all the low-order harmonics were at or below —80dB 0.
Square wave performance was excellent, with the Hz square wave showing negligible tilt and almost no curvature across the flats. Phase error at 20kHz was a little on the high side, but nothing to be concerned about.
Denon PMA-700AE Amplifier Review & Test
Damping factor was very good: Channel separation was good, with a best of 79dB at 20Hz, reducing to 72dB at 1kHz and 48dB at 20kHz, however the balance pma-700ze the left and right channels was very slightly out, with a 1.
Distortion was very low, as you can tell from the spectrograms.
With the tone controls engaged, the low-frequency response slopes down from 1kHz to end up 2dB down at 80Hz and a further 0. This is not a large error: Stability into an extremely capacitative load was excellent. The 1kHz wave was nearly perfect, and the 10kHz wave showed a pma-700qe fast rise-time with very little rounding.
You can clearly see the power supply limitation at 20Hz however, where the Denon returned watts With pmx-700ae 4O load, the second harmonic component crept up to —90dB 0.
Denon PMAAE review | What Hi-Fi?
As you can see, what little ringing there was was quickly damped. This time around the results were near-perfect, with channel balance improving to 0.
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. 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.

Denon PMA700AE Amplifier With Phono Input
This is exceptional performance, by any standard. The Denon was no slouch into 4O loads either, producing watts Even the two sidebands were an excellent —95dB.
mpa-700ae The overall THD figures are tabulated in the chart, at 0. At 1kHz, the Denon delivered a little more again watts, or David Ella and tested by Steve Holding Magazine: And for the price, excellent hi-fi performance.
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.
