Denon's popular M series gives you high sound quality based on the "simple & straight" concept. Circuitry is uncomplicated, signal paths are short, and all adverse influences on sound quality have been minimized. The circuit design and the way the chassis is built ensure that the sound you hear is utterly faithful to the original performance.
In an audio component where various circuits, boards, and wire layouts can influence each other, it is not possible to obtain satisfying specifications or sound simply by strengthening the power amp circuit. Denon has therefore eliminated three sources of noise to ensure that the sound is as clean as possible. Distortion from the input selector, electronic volume and power amp has been suppressed to improve the signal-to-noise ratio and produce an even smoother, dramatic sound.
You can also listen to music files from your iPod by simply connecting it to the USB port with the USB cable that came with the iPod. Digital signals from the iPod are transmitted as is to the D-M40 and are processed by advanced audio circuitry to produce a clean, high-quality sound. Moreover, the D-M40's USB port is not only capable of playing MP3 and WMA files, but also lossless FLAC, WAV and AAC.
