I've only listened to both in isolation so I can't really assess their technical prowess with respect to each other. They are very different in sound signature though, with the Semkarch being an energetic v-shape and the Kanas Pro neutralish. I don't think stacking them against each other is very useful as they clearly are in such different categories.
What I can say about the Kanas Pro however is that although I haven't spent much time with them yet, it's extremely likely they are going to displace the Simgot EN700 Pro from my best/top/fav spot. I love my EN700 Pro to bits but when I use it my QP1R DAP it doesn't really sound better than when I listen to it through my goto Audiotrak Prodigy Cube Black Edition with Burson v5i opamp DAC/Amp. In fact I like the EN700 Pro better on the Cube than on the QP1R as the Cube has a more engaging and dynamic sound than the QP1R to my ears. With the Kanas Pro it's another story altogether it seems and whereas it appears to just about edge the EN700 Pro on the Cube in technicality, when I use it on the QP1R it's like I clearly enter in another, superior, dimension of sound. In other words, the Kanas Pro scales up to the better source whereas the EN700 Pro doesn't. I did burst into spontaneous laughter out of joy and incredulity a couple of times at how good they sounded on the QP1R. Arguably I don't know what a good TOTL may sound like but this is really very very good. Someone on Ali rated the Kanas Pro higher than the EX-1000 (which is S- in Crinacle's ratings) and I am not surprised as I also have the EX-1000 (which I think is a bit overrated). How do the Semkarch stack up to that, frankly I don't know as I haven't tried it on the QP1R and I don't really care either, It's a very good sounding pair for "fun" listening and they won't touch the Kanas Pro for "serious" listening, that's for sure.
Well this is it, all I can say for now, it's early days with both, all to be taken with a grain of salt, new toy syndrome oblige...
