In general I do not write reviews, but in this case I like to do an exception. The purchase of the Denon RCD39DAR was a real stroke of luck for me. And for all those looking for a modern and joyful connection device with very good sound quality out, is likely to come in the narrowest range of Denon. (Sound) quality, handling and versatility, everything to my complete satisfaction. Met the small receiver (almost) every wish provided you want sound for large rooms with no party level, or climb the highest sonic peaks. For this you needed then perhaps a separate power amplifier with more power, or equipment that costs many times over. The most important thing for me at first: The Denon RCD-M39DAB sounds, provided appropriate speakers, really good. When choosing the transducer should be chosen not too power-hungry pit, because the lowest notes then swept under the carpet just once. That would be a real loss, because the M39 is a surprisingly Audiophiles device and paints a beautiful, complete, sound and strong three-dimensional image of any music in the room. The boxes offered for M39 Denon I can not judge, because I have not heard them. The operation falls conceivable from easy and has asked me to no great problems. Only the Channel Set the tuner requires a bit of concern with, supplied on CD Rom, manual. The key for me passages I then printed out to me simply. My iPhone has been recognized by the plug it immediately, and even here I like menu navigation and usability extraordinarily well. For reading the CD's, the Denon maybe a Sekündchen genemigt longer than other devices, but he played without complaint so far all discs from silver, older-edited. A via the optical digital input and alternates to the analog input connected high-end CD players convinced me sustained by the good quality of the internal A / D Wanldlers and the final stage. So from me a very strong buy recommendation
