surprised you found treble harsh. i thought it was rolled off. 

I found the treble even though not having the extension of the likes of KC06A etc, and KC06A sounded brighter, yet still seems to have peaks which contributed to the sibilance which KC06A doesn't exhibit in comparison. 

It has a rise at 8kHz and peak at 9kHz - right where sibilance can often hit.  I'll post the graph as soon as my review is finished. 

Thanks for the clarifications @Brooko. Looking forward to your review!

That's right where I'm sensitive at. Thanks for the review!

Thanks @sodesuka, appreciate the gesture
