finally got an email from Anthem.

The MRX 1120 has 4 extra powered channels and the toroidal power supply. The toroidal power supply offers less radiated noise when compared to a standard laminated core power supply – this would translate into less noise when you are using the internal amps or external amps.

The power in the units are essentially the same with the difference being in the power supply style.

DTS:X will be a firmware upgrade (we are expecting it this summer). This will be done the same as all firmware updates through the front panel USB.

Our MRX’s will not be upgradeable.


So, that basically leaves the question on how much more nosy is the non toroidal power supply and will that translate into audible sound degradation?
