"Computer says No"
I recently upgraded my audio system with the NAD C272 power amplifier. I was not quite happy with the standard (stereo) sound performance of the Cambridge Audio 540R surround receiver. A good surround receiver, but a bit flat in the standard stereo performance (though lot of people think otherwise, that’s why I chose this particular one). Reverting to a stereo system was no option for me, because I really enjoy surround music when playing movies or electronic multi-channel music.
By adding the C272 for extra power, the performance in playing ‘normal’ 2-channel music (which I still play 90% of the time) strongly enhanced, so I get ‘the best of two worlds".
The NAD power amplifier is stored out of reach, and has a convenient "Sleep/Wake" feature that activates the amplifier when receiving signal and makes it go into sleep mode when there’s no signal for 5 minutes.
But there’s a downside.
