You mention DVD.. ahh DVD is not going to be easily decoded by the usual DAC.Your DVD player would have to have the ability to put the DVD music/sound into two channel code suitable for a two channel DAC. Most DVD players will put out a multi channel code that the two channel DAC will NOT recognize at all, or just make a lot of clicking noises. (one of my DVD players does have the ability to output any codec into two channel for a DAC (a Technics DVDA-10)To include DVD multichannel output, you are stuck with a Receiver, unless you spend BIG bucks (as far as I know, and I do not know for certain that no reasonable priced two channel DAC does multi channel DVD.)One other thing is many used two channel DAC are very good.You can buy a good thousand dollar in it's day DAC for under $200. over on AudiogoN.
