Question about Denon Avr-X520bt

Works perfectly with the UPC Horizon Box. Simple installation, everything tip-top.

I don't know the ups box but if it has an HDMI output it should work. I have five different devices connected to the receiver (via HDMI) and they all work. The only small drawback is that the receiver takes a little time to switch (more expensive receivers from Dennon are much faster). For CHF 298, however, you can easily overlook this. Therefore, I recommend buying it.
