Interesting impressions! I haven't heard the B3's, but I personally find the reference nature of the tenores to not be as musical, toe-tapping and engaging as something like the KC06's. So to read that you find the tenores to be more musical than the B3's is interesting indeed, because I'm not sure that I want anything more reference/flatter than the tenores.
Perhaps I should have stated as well, I very much prefer analytical sounding IEMs to more musical ones. In fact, of all the IEMs I've ever owned (~15) and all the IEMs I've ever had the chance to listen for an extended period of time (~20-25), the only ones which would likely classify as being musical sounding are the Shure SE215 (sold) and KC06 (sold).
Hence when I refer to the musicality of the Tenore, this is in comparison with other IEMs such as the TF10 (half-half I suppose), Rockit R50, Audio Technica CK100Pro, Audio Technica IM02, Etymotic ER4PT/S, Havi B3. The Tenore might be considered reference sounding with respect to the whole range of IEMs out there right now, but in my arsenal of IEMs, all the other IEMs are almost certainly flatter / more analytical sounding than the Tenore.
I know from my experiences with the VSD1S and KC06 that I was hitting the limit of my V-shaped, fun treshold. Those were certainly a lot more musical than the Tenore. I guess it's just me. I don't like high quantities of bass and I don't like my mids getting drowned out. The Tenore offer me a really nice balance of being a fun-sounding but yet relatively reference-ish IEM. Hope that clarifies things!
