Can I Use One Channel Of A Stereo Power Amp?

Some of the NAD stereo power amps are bridgeable into mono.

I have had excellent success running one channel each into two Sunfire stereo amps.

The 300 watt version can be had for $800 or less.

Finding a good RF-reducing power cord will greatly enhance their performance. The ones from Marigo are superb, but they are expensive.

Use a dummy load on the unused channel.

what's the theory behind a dummy load? if there is no input, there is no output except some cross talk that made it into the unused channel which is minute. if using dummy load, one would need a fairly high wattage resistor I assumed.

Although not cheap, the MBL 9007 can be used both ways. Generally they are sold as 440 wpc mono amps but they can also be used as a stereo amp. When in stereo mode the power is greatly reduced to somewhere around 130 wpc.
