I love the small form factor of these amps and their power sipping frugality. Only complaints I've heard so far are some folk feel soundstage and imaging are still not 100% up to class a and a/b designs, and a few folk feeling the top end needs a touch more extension and refinement. Otherwise, glowing reviews about bass and a cool neutral presentation seem to be the sound strengths. Now, it's hard at times to really figure out who's comparing what to what on the internet, as well as a stranger's preference, so I figure I'd bring it up here and see what a few of my fellow Akers, many of whom I am confident of their listening habits and abilities, have to say. I'm confident you guys can deliver a solid foundation for me to work from.
