As many have said, Audioengine really built a business off of this format, and NAD has had a ton of success with their smaller and affordable amps. I think if Schiit can make this mini desktop amp as a mono or stereo amp, with the incredible advancements in topology they've made, and with the value they are known for, I think they could sell truckloads of them. The new Ascend Acoustics Sierra Luna that's coming out (fantastic development thread
here for people that want to read it) would probably be a dream with a pair of them.
I've owned an Emotiva Mini-X A-100 for a long time and it's a great amp that kinda fits on a desktop, but it's really an awkward form factor as it's just far too long, but it works alright under a small monitor. The Schiit amp would look far more beautiful in a Bifrost sized stack, maybe two amps, and a Saga on top. That's a dream right there.
If they did this, I would really, really hope they listen to those of us that want a custom rack system for their Schiit. I know it's a really low margin product, and likely a PITA, and not at all what they would want to spend their time making, but the iFi stuff is just so cool. If they could make a stacking system that gave a little more ventilation to the components and really made it look cool, I think people would like it. Especially if you're going to start stacking Schiit 4 boxes high on a desktop. I've been really wrong on this thread before, but hey, just my thoughts.
