@mijostyn , those experienced in electronics and the design of electronics products can view photographs and make generalized comments about the quality of designs, based on experience, good engineering practice and a bit of common sense. Like anything else, it is not perfect, but there is nothing wrong with it, and too many of what look like bad design decisions will make you question well what else is wrong.
There is a quite heated argument going on (mostly unrelated) to the LSA GAN amp. A quick look at the pictures of the interior by someone knowledgeable suggests a really poor decision on the orientation of the AC supply, with a 180 flip reducing the length of the AC wires and their potential for noise coupling to audio, and the ability to shorten the wires (and potential noise interaction) for the DC wires out to the modules. We also see PCB mount XLR connector with wires soldered to them, no hold downs for the wires, no supplemental case grounding connection, etc. The modules appear off the shelf. When you couple the measured performance, the use off the shelf modules, and what comes across as a poorly engineered product, a conclusion similar to the video, i.e. this is over priced for what it is, is a viable conclusion. How will it sound? Like off the shelf modules in a box which you may or may not like.
