250 Pro

Not very helpful.

Well, why did you decide on a D200 rather than a D120? 50% more expensive and not a great deal more power.

I would suggest that D250 owners chose that model because:
1. they wanted the extra 30 watts
2. they understood the casework provides better thermal dissipation, and so better current delivery at high loads for a longer time period
3. they liked the option of going dual mono to D800.
4. they listened to the D250 as well as other amps, and decided, based on listening, that the D250 was the better choice given their own judgemen, budget and upgrade options.
