Comparing a 220 Pro to a 200

[Damon]

used D200 sell for much less than the upgrade price in Canada. 

Not that it is worth a lengthy debate, but my check on CAM shows the cheapest D200 is $5,250.00; that is more than the upgrade cost me. There is also a companion for $4,750.00. There is variation, naturally, but it is all up. The Expert line is now 'the previous generation' so it is logically worth less on the used market. But it does not change the intrinsic value or sound quality of the amp. If it was excellent before, it is still excellent.

But given the prices generally of audio equipment in this range, the cost difference is probably a secondary concern for anyone considering a D200 to D220 Pro upgrade versus a move to a D400. I'm thinking that the positive side is that if one can compare the two options, then the cost difference is not likely to be the deciding factor.
