There are some select after market company's who upgrade the 3800bdci. The power supply ect. I know a guy up in Minnesota, part of the R&D team of Audio Research & Wadia, went on his own modifying power supplies ect. When your unit is out of warranty your problem is a quick fix. There is also a group that specializes in upgrading the Denon product line. I talked to them, have never had work done by them. If interested let me know, and I'll dig out the sites.
