As for degrading the sound quality through software well I am sure due to the thermal management requirements being completely different that would be more a safety requirement , rather than any deliberate act.
I have noticed that they are different in some of the pictures that have been posted over the last few months. The 250/1000 ADH class D board appears to be gold across it's entire surface area, whereas for the 220 in is the main central area only, they definitely look different. I did wonder if this was purely cooling related? Do you know if there is some difference in the actual electronics?
