More detail is the Holy Grail. How that information is presented is where things get tricky.
I agree. The new amp is a second generation Class D design that uses GaN transistor technology. Seeing what the latest and greatest technology can (cost effectively) do with the sound I hear is always of interest to me. Done well, technical innovations can yield better results than was possible prior. The amp it replaces use a Hypex NCore Class D module that is now several years old and not GaN. That replaced an amp with older Icepower Class D technology done very well at the time by Bel Canto. None of these amps are slouches but each sounds much different for sure.
