As asked,the internal impedence of the Orpheus is 2.5 ohms.This is an astonishing figure,that only(as of now) the Air Tight PC-1 matches,though the Air Tight may actually be better,in this measured parameter.I am not so sure about the PC-1 vs "O" on an overall comparison though.In truth the "O" is just SO good that I am currently in the "could care less" state of mind.
AMAZING in virtually every way!Sorry for this sort of over the top post,but it SO outclasses my beloved "V" that I literally "need" to post this!...As to the "V",I had previously owned the Temper and Temper Supreme,and the "V" absolutely was the best of the lot!I loved it,in every way.Yes,it was/is sensitive to set-up,but before I upgraded to the "O" I was just SO happy,that I sincerely questioned why I should spend the extra money.Though I know the "O" is far superior,the "V" is still an amazing cartridge!Speed/detail/and much more authority than some will let on.
Yet,the "O" just put my jaw on the floor,it is totally astounding!!This absolutely "needs" to be heard to make any sensae at all!The "O" wipes the floor with the "V",in dynamic terms,and has far better tonal qualities.
Please don't take this as any negative "shot" against the "V",which was amazing in resolution,detail,balance and had fabulous stage depth and presence.To get all it has to offer though,one really MUST experiment ALOT with set-up variables as well as having a group of reliable audio friends to reinforce these impressions.
I am ONLY talking in the frame of Transfiguration designs,as I have heard almost all competitive designs and love them all...Almost! -:)
Good luck.
