I'm very familiar with these and had considered them for a while. I do like the idea of them; please don't misunderstand.
One of my main goals has been in going full Class-D with my amplification, however. This will be a step along that path. Moreover, I needed to keep my cost low for 4 channels of amplification in the near term while also having the ability to
experiment with something that can fully power a Driver capable of absorbing 5000w peak power at 6 ohms.
(Yes, this is an extreme outlier situation and I
DO NOT anticipate ever pushing that!)
Regardless, this is a kickstart purchase to allow me to start moving forward with my first project. Hell, I may even reach out to Amir and see if he wants to measure it. We'll see.
