Thanks for the replies, sorry I'm late getting back, been travelling -
Road test of KMC 1: Excellent! It goes loud and sounds clean and tight. Charge goes until you're at the next power point, even if you're somewhere where there aren't alot of those. In this day & age, it's annoying to have something designed so you actually have to read the manual (like "how do you mute this again?", oh, volume down + off button, for an intermediate amount of time), but otherwise only complaint that KMC3 has no battery like the KMC1. I've had the Bose Soundlink 2, the Jawbox, the Foxl, the Sony SRS-BTX500, and several others - KMC1 beats them all by a great length.
Am considering getting two of the KMC1, with the splitter so it becomes proper stereo sound. That is A LOT of sound for the size and weight. But yeah, would have got the KMC3 (two of that, even, maybe) but no way am I starting using those batteries from the 70s again.... I'm looking for a shop with a refund policy so I can get two KMC1s, see what I think and decide if it's worth it. It's not really stocked a lot of places, though, is it ?
Ayone heard anyword if/when there might be a gen2 KMC-series ?
Again, thanks for your help
