Can’t help you with comparison bacause I know NOTHING about Bel Canto, but I do own some Legacy Monobloc amps (450 wpc) and high current preamp. (I believe they have a less powerful version as well, although I’ve never seen them)
along with a couple pair of Legacy speakers
they are class A/AB amps (Not class D) IMHO, NO better amp for the $$. They drive anything I throw at them effortlessly!
Highly recommend them!!!
The biggest problem is finding them? Rarely ever see them for sale. If you know of some for sale that your not gonna buy?? Please pass the info on!!
Cheers!
