Hi.. I am thinking that if manufacturers would listen to this suggestions, it may be possible to create all audio devices upgradable like computer CPU in future. If it has been practically done before, for imagination, my receiver can be easier upgraded from Dolby D EX to Dolby True HD, from DTS-ES to DTS HD, and even screen panels, jacks, and electronic parts can be replaced without spending lot of money.
A combination of best components from various brands in one receiver would also, for instance, produce the most desirable performance machine.
Just my imagination..
