I'm a little confused (who said that was easy???) by what I'm reading in various places. Some say that there can be no upgrade for my already upgraded Denon AVC-A1SE (it cost £600 and had to go back to Denon UK, as it's now called, for the modifications) but others invite our American friends to register for the PLIIx etc upgrade for their 5800's. Would some knowledgeable person please tell me what the latest position is in the UK? Will the upgrade be offered or not? If the answer is affirmative, any idea when this might take place and how much it might cost? Thank you. Jim PS I've not had the Denon Link upgrade done as I don't have a Denon DVD player. ========================================================= AVR-5803 Dolby Pro Logic IIx/HDCD Decoding and DENON Link 3rd Upgrade Registration To register for the Dolby Pro Logic IIx/HDCD Decoding and DENON Link 3rd upgrade of your AVR-5803, please fill out the form.
