Are the parts in a comparably-priced A/B amplifier (Gryphon, D’Agostino, Soulution, etc.) more expensive than the ones in this amp? How much more expensive?
The cost differences are massive >50, especially when you factor in the power supplies also (SMP v Linear), for the same wattages compared to one of A/B’s you’ve chosen.
That’s why the mighty buck increase looks so tempting to the Class-D makers and swingers.
To give you an idea just one of the power supply caps in a linear amp you mentioned can cost as much as the whole SMP power supply in a Class-d
