emailed denon after reading various threads on here i enquired as to whether they would be updating the 500sd or bringing out something to replace it in the not to distant future- with hdmi connectivity. the denon response was NO as the 500sd wouldnt support hdmi connectivity. I also enquired as to the troublesome fan noise i have been reading about- i asked them if they were able to build firmware to eradicate the noisy fan problem, ie fan kicking in at higher db levels. denon response:In terms of the fan noise, this is down to a fault with that particular DHT500SD unit, as we have tested this and have concluded it does not interfere with the movie. If you have any further queries please do not hesitate to contact us so does this mean an inherent fault amongst all 500sd units????
