At a minimum, the software is different between the 220 and 250. The power supply with the 250 must have additional reserve power over the 220 given the deltas in power when configured in mono. To me, the chassis and remote definitely looks better.
My current reference speakers are Tyler Linbrook Signature Floorstanders, with all SEAS Excel /Millennium drivers, upgraded crossover parts and internal wiring, gets down to 25hz, and has an efficiency of 90db/w @ 4 ohms. Had previously tried both a single and dual D-Premier setup with these speakers, and there was not any discernible audible difference between the two setups. Have sent a D-Premier back to factory for upgrade to a 250 Pro. Pretty confident that the extra reserve power from the 250 Pro will be a welcomed upgrade.
