Elsewhere this amplifier is about as loaded as these things get. It will decode all current home cinema sound formats from Dolby and DTS, including Dolby Atmos in 5.1.2 form. The ability to handle DTS:X is a software upgrade away, expected later this year.
Spotify Connect, Airplay, Bluetooth are all supported, as is Internet radio and streaming from a NAS device on your home network. Denon has tried hard to make this amplifier stable when using wi-fi, even in electrically noisy environments, and it works well in our test rooms.
Helping matters is a new-found ability to work in the 5GHz waveband along with the 2.4GHz of its predecessor. Even so, given a choice we would still stick to using an Ethernet cable for the extra stability it provides.
The 2300 will stream just about every format across a network including 24-bit/192kHz PCM and DSD in both single and double speed form. The latter, along with the ability to stream AIFF files, is new for this model.
The X2300W’s power output is unchanged from the last version and rated at 7 x 150W per channel. Impressive, but it should be noted that – just like every other major AV amp manufacturer – Denon is quoting figures measured under very generous conditions (six ohm load, 1kHz, 1% THD and only one channel driven).
That output drops to a claimed 95W per channel into an eight ohm load, measured across 20Hz-20kHz with distortion held at 0.08% and two channels driven. The latter is closer to the way measurements are taken with traditional two-channel kit.
