NAP 300 DR

Any reason why?

Best ask Naim directly.

Probably easier to spot the DR label on the back?

At a rough guess about 396500 if this helps

Rattlesnaic-

I thought more like 396501 (roughly)

But watch out for the fake stick-on DR labels on that famous auction site.  It wouldn't surprise me if that chap who puts NAP500s up for 24 hours using different user id's, but the exact same pictures, cottons on to this potential 'DR' goldmine.
