Which A/V receiver to choose (NAD, Denon, Onkyo)?

[admin_exported]

Hello,

I have a pair of B&W 683's and need an A/V receiver to power them up. The ones to choose from are:

NAD T775

Onkyo TX-NR3007

Denon AVR-4310

They all fall into the same price range.

Also, what do you think about this new feature of NAD - MDC Upgrade Modules?
