I concur. Man, I wish I would have been able to keep this review tour unit. I've just put up my review on these beauties. I had the Fidue Sirius right after these, and the Sirius didn't move me as much. Some of that is the price. The Sirius is better, but not 5x the price better and a bit too rich in tone for me. Beautiful headphone, the Sirius, but if I could keep one of the two, I'd keep the Pinnacle.
Check out the review here, if you like.

Great review (and choice of video clips). Getting to hear the Sirius afterwards must have been a real hardship, too - only recently discovered Fidue (and the A83, not the flagship, sadly), but if the Sirius sounds better than the A83 then those are two seriously high grade IEMs to be treating your ears with.
