Yes, they don't advertise, but have been around more than twice as long as either of the two companies that you are considering. They are made in America and are completely wired point-to-point without circuit boards. You might want to have a look at their website, which is as minimalist as the amps and, if you like what you see, and if the design ethos is consonant with your objectives, have a read on some of the audio chat sites and get some user feedback. I don't own Quickkie amps, but were I in the market, I would purchase them over either of the other two marques. But that's me and doesn't help much; the reason that all three are around is that they all offer good value and performance, with different sound qualities and various power outputs.
