I'm afraid not - I can't get the Tenore easily under $80 and, well, I had already spent $80 on the KC06As. That said, if I could get the Tenores at the prices guys are getting them at before I'd bought the Ostry, that would definitely have been the choice I'd have made. I was unusually impulsive with the KC06A purchase, just figured I'd give it a shot especially considering that there was a limited amount available in the first batch.
For sure it sounds like the Tenores are something special, even if I do personally feel people are going a bit overboard. I got accused of hyping the Ostrys in the Tenore thread when I pointed out someone being strangely defensive about the Tenores, which to me actually just confirmed my assessment that people are being hyperdefensive there. I don't actually care enough about the subject to say much more there so I'm not.
My basic assessment of the KC06A is that the bass is very, very nice and vocals, especially female, are euphonic. There is something not right in the treble, though, but it doesn't highlight sibilance so I'm not too bothered. "Treble-heads" might not be so forgiving, though, so YMMV. I don't like the rubbery cable, but it's not enough of a problem to make me not want to use it - I guess I just really like a braided, non-springy cable. Accessories are good, imo, I do like the tips a fair amount but I'm using the Sony Hybrids regardless. They seemed to have the bass under control better than stock tips - though I will say that the bass, as much as there is of it, doesn't give me the sense that it's ever out of control. Just the Hybrids seem to present it a tad tighter.
I'm not likely to do any more in-depth of a review than that because... I just don't care enough . I like the earphones, but I don't feel like I need to justify my like for them or get a bunch of other people to like them. I'm happy to share my impressions with the caveat that they are my impressions.
