Hi There, My mother is looking to buy a Dennon D-M51DVS from the internet, But has read the following statement from : http://www.usa.denon.com/dealers/dealers.asp?l=1 WARNING TO VALUED CONSUMERS: The warranty on DENON Electronics products is NOT VALID if the products have been purchased from an unauthorized dealer/on-line E-tailer or if the original factory serial number has been removed, defaced or replaced in any way. Recently DENON Electronics has become aware of numerous instances in which such serial number tampering has occurred. Unauthorized dealers/on-line E-tailers and/or their suppliers frequently alter the serial numbers in an effort to prevent manufacturers from tracing the supplier source. DENON Electronics sell products through authorized retail and on-line channels to insure that consumers obtain quality pre-sale and after-sale support and service. PROTECT YOUR WARRANTY. Buy from an authorized DENON Electronics dealer/E-tailer. Check the unit and its packaging to determine whether the factory serial number may have been altered. If in doubt, call DENON Electronics at (973) 396-0810. She is now worried that if the system goes wrong she will not be able to get it repaired under warrantee. Although this statement is from the USA Site(there is no such statement on the UK site) Has anyone had any experience of this & is she right to be cautious? I have no problems myself buying from the net, But the last thing I want to do is recommend something & then it back fires! I would appreicete your views on this & also can anyone recommend this model or similar (bearing in mind that the size is a factor). Thanks for your time.
