I also think Bryston should make more devices compatible with the MPS2. Why is it not possible to power the BDP or BCD from this power supply. I think in 95% of the cases it only drives the preamp.
As an electronic engineer I have been wondering (no schematics available) if I could put the outputs in parallel. I have a non-Bryston phono amp that runs on 12V/ 500mA. But the individual outputs of the MPS2 are only capable of 350mA (if I remember correctly). Putting 2 outputs in parallel could double the current delivery. Obviously Bryston will not recommend this, or support it.
Also the active crossover 10B-STD and 10B-SUB can be ordered to be powered by the MPS2.
