I currently own an AVC-A1SE and have just purchased a DVD-3910. I would like to make use of Denon Link but can't with the current amp. Here's the dilema: I would love to change amp to AVC-A1SRA but can't afford to so am considering the AVR-3805. Will I notice a difference in sound quallity...hoping not, due to advances in tech. Also, will I miss the THX post proccessing which is not on the 3805? What the 3805 has that the A1se doesn't is Up Conversion to component...how well does this work?? I suppose the bottom line is, am I better off with the A1SE or the new 3805?? Comments would be appreciated...many thanks.
