I have a pair of LCD3f and HE90 in hand. Many of my friends have auditioned my system recently.
I found there is no consistent review that Orpheus is definitely better than LCD3f. And almost every non-audiophile tells me that LCD3f is better than Orpheus..
All my non-audiophile friends have preferred my 3Fs on the Audio gd he-9 at the time to the 009 on Kgsshv.
I have heard the he90 on a couple of occasions and every time I preferred Stax 007mk1 or 009.
