I have two typical categories of amplifiers, Korean and Brazilian. So then you have different topologies for instance S&I and Zenon. Funny how this video was released as I was responding to an SK4500 repair request.
Good job on tmhe review.Can't say enough of how much i love this amplifier and running 4 12 audio legion gladiators.This amplifier stays cool to the touch after hours of use but i wont go ɓelow one ohm and run 300. Amp alternator.
I love this AMP. I run it at .05 Ohms and 1 Ohm with no issues. To me Korean Amplifiers sound better than the Brazilian. Bass seems Deeper and thicker with Korean boards.
