Some interesting observations after our most recent headphone meetup here. While other amps may have been voted more proficient, many comments for the Makoyi were on being the most fun and musical. One stark comparison was versus the Neurochrome HP-1 (another Alberta-made amp) right next to it. People were swapping back and forth and almost universally felt the HP-1 was the more "technical" one, but the Makoyi was much more enjoyable.
I'm currently waiting on some new tubes to come in and will report back.
It's also worth noting that the pictures don't really do justice to this amp. Yes it's a simple red block, but the fit and finish is just great with the textured surface, and there is a satisfying heft when you hold it that tells you how much iron is in the thing.
