I love the guys who cheeped out or paid a bit more for a "brand" badge and the supposed support that comes with their supposed premium purchase. Fullbridge is cheap power, no dampening and always on the edge of failure. Marketing this chimera is tricky, expect a full 30% return for various reasons. Price a Salt 6 and get back to me... lol.
I prefer known tech like strong half bridge Korean type boards with REAL potential power. Boards that don't fry and premium caps that don't blow smoke, being able to handle low impedance and pretty much require it to make sick power. Then there's the inputs and grounds...
. There's a simple current/voltage/stability to every amplifier and the good ones are audio crack to those who are in the know. Caps, trace size and thickness are what? Durability and potential power if done right. Extras like 24db/ filters and durable pots are rare... add internal cooling and you get pricing
I suppose its me wanting quality and durability, You'll pay a ton more but will have options over cooling and impedance to make those ratings into reality.
Just an opinion and view from the cheep seats... idk competitors views anymore as I walked away on top of my org/class after 2yr being there.
Who knows?.. nuthuggers on cheep power abound but lemme ask them... am I wrong?
