You’d know more about the individual parts and their ratings than most people including myself. I agree, they are similar in construction to Crest amps. Not necessarily a bad thing. It’s very simple inside, what kind of protection does it have?
There appears to be many items that aren’t well secured. This amp may not survive long on the road. It certainly wouldn’t survive the Crown or QSC drop test.
I’d still want an experienced ear to beat them up next to other amps. Remember Elliot, the first & last lesson in SMAART is if everything says it’s good but your ears say otherwise, it’s not good.
