Basically, I support both the positive and negative points we in the Rezesionen here - this I have all read before I decided to buy - also external reviews.
The biggest plus of this relatively low-cost AVR is also my most important criterion. The sound!
Compared to my older pure hi-fi Denon PMA-510AE are as sonic worlds!
I run the X1100W with a Jamo 608 speakers 5.1 system and can dispense entirely with an active subwoofer, both in 5.1 and in Hi-Fi mode. The sound is very present without over- or understate in all areas at certain frequencies. Depending on the input source, bass and the surround speakers can be also set. I had to do, because even after the calibration of the boxes the bass in the cinema operating just too fierce.
For the sound I give definitely 6 star!
The multiple vulnerabilities addressed are for me constantly breaking off Wi-Fi and Bluetooth - annoying immensely when you're just in one of two ways on the go.
I have found no regularity where this sudden disconnections could come, which is but definitely on Denon AVR.
Here I hope to repair by the manufacturer!
