I have for sale a Cambridge Audio CXN. This is a great unit that does streaming (UPnP, Spotify, Airplay, hard drive, etc), will play from Bluetooth (via optional adapter, included in sale). I don't use Roon but since it has Airplay I believe it will work as a Roon endpoint too. You can control via apps on phones and tablets easily.
It also works as a really good sounding DAC with digital inputs, and has balanced XLR outputs, which are rare with this type of unit. There's a nice remote control and a big knob on the front. All in all a great unit. Only selling because I'm moving to Bluesound for family convenience.
There are no operational or sound issues. I'd rate a 7/10 conservatively just for some light scuffs and overall wear. It was never abused, but it's not a brand new unit so I'm being fair.
These go for ~$1100 new, plus I think the Bluetooth dongle is still an optional extra. My price is $700; at that asking price I'll do no Paypal fee, and offer free shipping for the continental US. I have the original box, remote, power cable.
