All the more reason to try the Denon first. Who cares if it blows up? Better to use it as a guinea pig. See how hard you need to run it, whether it heats up, blows up, whatever, and then use the results to help choose how much power (and transformer power) you need if you decide to upgrade.
I found some technical analysis of the AVR-1700, which was a mid-end model actually from what I found online:
"In the lab, the AVR1700 delivered technical measurements typical of a low-to-mid-priced receiver.
The maximum power output at the onset of clipping was measured at 86.19W RMS into 81/2 with a THD of 3.07 per cent. Denon quotes an output of 70W with no more than 0.5 per cent THD.
Yet 0.5 per cent THD might be considered a tad high in today's age of ultra-low distortion amplification. Employing HCC's unique Fidelity Firewall (a measurement showing maximum output and low distortion) we can reveal the AVR-1700 delivers just 60.8W at 0.118 per cent THD.
We were more worried by the overall frequency response. In stereo mode a 30-point sweep from 25Hz to 20kHz at the Firewall Output revealed a 0.5dB peak around 150Hz and a droop of 0.3dB from 200Hz to 500Hz, bottoming out at 800Hz.
Employing a multitone (22 frequencies applied simultaneously) at the industry 1W/8ohm level, confirmed this mid-band muzziness with a measured variation of 0.8dB peak-to-peak which (if you have keen hearing) may just about be audible, especially on music recordings."
And here's an excerpt from the HCC review:
"I was actually rather impressed with how this Denon performed both with music and movie material. Musically, the AVR-1700 has an open, inviting character particularly suited to solo vocalists. I listened to, amongst others, Paula Cole's This Fire (Warner) and Rebecca Pigeon's The Raven (Chesky) and apart from a slight restriction in terms of image depth and width was surprised with the results.
The Denon isn't shamed by a high-quality pair of loudspeakers and is equally at home with a modest home theatre package, but a little extra spent on speakers isn't going to be wasted. I couldn't find much to complain about when it came to bass-heavy material either; unlike some previous Denons, the AVR-1700 can pump out a forceful bass line such as that during Yello's The Rhythm Divine.
The six DSP modes are moderate, the best being 5CH stereo, and should be used judiciously. Turning the rear and effect levels down from the defaults helps a great deal. Experiment for the best results."
