I've been listening to the Altone200 for the last few hours.
Quick impressions:
The bass is nice. It finds a good balance between delivering a weighty punch, and staying tight. Sub-bass could be better though, and texture seems to be lacking a bit.
The mids are pretty nice as well, with a slightly dry quality to them. I sometimes wish they were more present though.
Treble is where things start to fall apart for me. I'm hearing a few spikes here and there that make things sound pretty rough overall. Timbre isn't particularly good, nor is overall refinement. I find it pretty fatiguing after a few minutes, actually.
Soundstage is also another weak point. It's a bit closed in for my liking, and too left-right-center for me. It isn't exactly a masterclass in depth or height.
Overall, I find the Altone200 to be pretty decent, but ultimately lacking compared to the likes of the KC06. The KC06 is more detailed, more open sounding, and a good deal more refined in its presentation.
I'm not sure what to say of the value proposition. Price-wise, it's the cheapest triple hybrid out there...but that's about it. I've heard quite a lot of hybrids, and the Altone200 is second to last the list when it comes to taking advantage of the technology...right above the H-100. The H-200 from T-Peos is a much better option, IMO.
If you're looking at the Altone because it's a well-priced hybrid, don't. You can get better raw sound from even less expensive options, IMO.
