Superb review, im considering either this iem or the Hifiman RE800 as my next potential purchase but now im confused as to how they compare. Your comparison of the two seems to be the opposite of B9 Scrambler's. Im looking for one that is more detailed, with faster transients, better instrument separation and crunch.

Perhaps B9 Scrambler can also chime in?

Thanks. Well, IMO, you know my advice would be the POLARIS big time. And that, especially reading the type of soundsignature you search. Instrument separation is razor sharp with Polaris, not so much with RE800 that have a more ''analogish'' presentation. I'm kinda harsh with the RE800, but I think its in a objective way, even if well, my ears are different from B9!
