Things have changed a lot since my current Yamaha receiver and its outboard Dolby Digital decoder from the late 1990s. Dolby Pro Logic has been improved twice to Pro Logic IIx, I've seen. dts decoders are usually a part of even minimal receivers now. Dolby Digital seems about the same but has increased from 5.1 to 7.1 at even moderate prices. Video upconversion is fairly standard, though only to S-Video on inexpensive receivers. More expensive receivers often have Burr-Brown video DACs. Multiple digital inputs are standard. Are there technologies of specific interest that I should be seeking? I'd much rather stay with Yamaha since I know what to expect but I won't say that I won't consider other brands. I'm thinking that more than $800 is too much but it depends on how compelling the equipment is. $1000 would definitely be too much. Thanks for your help!
