The Denon AVR-X3000 is a seven channel, network capable home theatre receiver with a clear preference for HDMI connections.
Each of the amps is rated at 105 watts continuous power (two channels driven) into eight ohms. Disappointingly, the unit is rated to support only loudspeakers with an impedance of six or more ohms, which rules out quite a few high quality models. If you want to go for more difficult loudspeakers at some point in the future, you can make use of the preamplifier outputs for all seven channels to add higher spec amplifiers.
There are plenty of inputs: seven HDMI, plus component and composite video, analogue audio and digital audio in both optical and coaxial varieties, and of course Ethernet and USB (the latter on the front panel). Missing are any analogue video outputs. If you do want to use an old analogue video source, then you will need to rely on this receiver converting the video into HDMI format. Which it can do. It can also upscale all video inputs — HDMI as well as analogue — up to your choice of resolution, including 1080p and 4K (if you have a 4K display).
The unit also supports a second zone, with a dedicated HDMI output for that purpose, plus stereo analogue audio and the ability to redirect the surround back amplifiers to driving second zone speakers.
AM/FM tuners are so ubiquitous in home theatre receivers that I rarely even mention them in reviews. But this receiver is FM only. If you want to receive one of the AM-only stations in your area, you will have to hope that's it's available video the vTuner Internet radio facility provided by the receiver.
The receiver starts up the first time with a wizard that guides you through the full setup, including connecting speakers, source devices and your network.
Even though quite a few models use the same Audyssey MultEQ XT for auto calibration, this receiver was one of the extremely rare number that actually got my speaker setup more or less right. It declared the front stereo pair to be Large and the centre and surround speakers to be Small. It allows different crossover frequencies (below which the bass is redirected to the subwoofer) to be set for each position. So you can have the front speakers as Small, but with a crossover of 40 hertz so that the really deep stuff, which your front speakers probably won't handle well, still gets delivered by the subwoofer. It chose 150 hertz for my surround speakers, and 60 hertz for the centre channel. Since all three are identical, that shows the effect of room acoustics. I lowered the surround speakers to 80 hertz crossovers because I know my subwoofer isn't good for anything much above 100 hertz.
