The only way I can get the Tenore's bass to hit harder than KC06 is if I use a deep tip insertion, at which point everything else sounds hollow -- mids/trebles become recessed, feels like I'm in a vacuum standing next to a subwoofer. Tenore has big issues in terms variation when it comes to how you put them into your ears which makes it difficult to use as on-the-go iem's. I'll be getting the Meelec Biflanges from you soon though, so we'll see if that changes anything. :)
I'd recommend you try Heir tips (from lunashops) on your KC06.
