I have listened to both the HCA-2 and the Classic 250 amplifiers in back to back comparisons at a dealer.
As good as the HCA-2 is, the Classic 250 is a significant step up in the performance areas of bass authority, midrange and dynamics.
I could hear the differences between the two amplifiers immediately and know why the dealer concerned listens to the Classic 250 and not the HCA-2.
It was very hard to listen to the HCA-2 after listening to the Classic!
