I auditioned them at Sevenoaks Sheffield.
When I was buying the receiver, Denon had recently increased its prices due to the weakening Pound. This completely put me off, so I didn't audition it. I checked Onkyo, Pioneer & Yamaha....& liked Yamaha the best. Denon 2310 is well specd & should nicely match your system.
However, I would recommend that you audition the receivers, as they sound very different from one another.
Is Southampton near your place? There's a Sevenoaks there. Check
www.ssav.com for your nearest store. Otherwise, go on a Saturday to your nearest city where you'll find some hi-fi dealers to audition them.
