Summary: I can't really compare the quality of audio to other receivers, but it does a good job with my 5.1 channel setup. The problem is that there is no built-in wifi, and when using an internet bridge (Netgear WNCE 2001) the audio stutters. It seem Denon is stuck in the dark ages when everything plugged into walls.
Summary: Overall, this is a good receiver. I've had it for 6 months and the audio quality is great. Unfortunately, it suffers from a firmware bug where AirPlay streaming audio will pop in and out every 2 seconds. The only [temporary] fix is to unplug the unit and plug it back in again. I've called Denon about this issue, but their only suggestion was to factory reset the unit, which fixed the issue for a number of weeks but it has started reoccurring again.
Summary: FINAL UPDATE: Denon did finally produce a firmware upgrade which fixed the Airplay and network stuttering for me. They have also updated the iPhone Denon remote control software several times. Things now appear to be stable and working as designed. UPDATE: After a few months, and a couple of firmware updates, I have to report that the network audio is not stable. This covers audio from Airplay, Pandora, etc.
Summary: This is a 5 star receiver, but I have enough problems with bugs that I have to rate it 3 stars for the moment. Sometimes switching between HDMI ports takes several tries to get it working. The networking side of this device can also be quite buggy at times. I suspect that all of these bugs could be fixable with a firmware update.
Summary: Ich halte schon lange nach einem AV Receiver Ausschau, der in der Preisklasse bis 500€ einen guten Klang und eine unkomplizierte Bedienung bietet. Da ich kein Surround benötige, liegt der Fokus vor allem auf dem gutem Klang im Stereo Bereich. Die Musik wird ausnahmslos über Airplay zugespielt, weshalb die Funktion des Receivers kaufentscheident war.
Summary: Ich habe mir den Denon 1713 vor allem gekauft um damit Musik von einem Medienserver per DLNA zu hören (Ich hatte mir dafür das Western Digital MyBook Live 2 TB gekauft). Dafür habe ich alle meine CDs in FLAC-Dateien umgewandelt und auf den Medienserver kopiert. Den Denon AVR 1713 und den Medienserver habe ich per Netzwerkkabel an meinen Gigabit-Switch angeschlossen.
