You know, speaking of psychologicality :-P I always think I get imbalance due to fit here and there, but the more I think of it, I'm pretty sure sometimes it must be the earphones. Today, when I was comparing the kc06 and tenore a bit more, I put my tenore in one time and couldn't get the right channel to be as loud as the left. I thought it was my fit/seal/ear, but it never got better. But when I switched to the kc06 there was no imbalance, so I know it wasn't my ear. That leaves fit and seal. As it felt normal and sounded fairly normal, it seems to me I might have had imbalance too. This happens now and then, but I just play with it until it fixes itself or I try to ignore it until it goes away, assuming it's pressure or something.
Ultimately though, I really do think sometimes I'm being to lenient, and that there is no logical reason for the drop in volume, which is sometimes roughly 20-30% or maybe even more. I don't know. Maybe not, but it seems odd that fiddling with it sometimes doesn't get it to go away, and others experience imbalance. Seems more likely I'm actually getting imbalance... poop.
Now that I've personally had a good long time to compare the tenore and kc06 (assuming both are in their proper condition) I'm pretty confident I can give a solid final impression as I hear it. Then we can see how gnarlsagan finds them to sound.
First, these are probably a tricky iem, because the fit is shallow and the seal and isolation aren't always ideal. But for me, especially wearing them over the ear, when I can get them a bit better fitted, I find them very similar to my reference tenores with the following differences:
The tenore has better mid range and sounds more flat throughout the spectrum. The kc06 has a more prominent treble. I personally don't hear this as boosted or bad in any way at all. Using eq I can basically flatten the tenore treble based on the previously seen graph and it sounds closer to the kc06 treble. However, the kc06 has more "main" bass region. I don't hear any mid bass bloat, but the bass is a bit stronger. The tenore is very neutral in the bass, with the treble sounding slightly soft in comparison to the kc06.
The biggest difference I hear, which is a double edged sword, is there is some dip in the low treble/upper mids. This gives the kc06 a very nice depth to it, instruments sound more distinct and stand out more in their own space, but at the loss of a bit of mid presence that gives strings and somethings a lush sound. The tenore, having more presence/amplitude here, gives a more detailed "overall" sound. I hear certain instruments that sound a touch (very slight) recessed on teh kc06, while on the tenore they are more even in the mix, hence the flatter overall response. But on the kc06, while some of that region is very slightly lower, the rest of the entire spectrum has a bit more of a natural, real sound to my ears. Things are a touch darker than the reference tenore, because of the dip and added bass, but sometimes this ends up sounding more real to me depending on the song.
I really find the two are almost equal in my opinion. The tenore excels at flat overall comprehension and revealing every single detail evenly as mixed. While the kc06 brings the details out more distinctly and with more depth and room ambience, but at the cost of a very small loss of some mid range distinction and body.
If I eq the tenore to sound more like the kc06 treble it is very very impressive, and simply lowering the bass of the kc06, boosting the mids or both makes them extremely impressive as well. I still can't decide which I'd prefer if I could only have one (which is sort of a goal). They both make me hear different focus areas, while both sounding very reference overall.
The only thing that would skew these impressions for you might be if you get a bassier tenore or the kc06 (or tenore) don't work well with your ear canal or fit/seal. But for $60 each, these things are insane sound quality. "Quality" on the other hand. I'm starting to wonder. The tenores are getting a bad track record here. The kc06 not so much, and yet reverse polarity on a driver causing inverted phase? Really? That means first, they failed to wire them properly and second, obviously no one did any decent testing of the unit. But if that is 1 out of 1000 that's not too bad. I haven't heard too much against the ostry yet...
