Hi My main listening will be with earphones the Etymotic Research HF5 I hope! I haven't actually received them yet . I mostly listen to B&W C5's & a pair of Phillips Fidelio's.
My speakers are the AktiMate Mini's They have a volume control but it would be nice to have one on the desk so I'm interested in the VarOut mod, but not sure about the 1-ohm mod. I have only got used to IEM's in the last year but for me there will be no going back. I love their unobtrusiveness, well once you get used to having things stuffed in your ears & I don't sweat when wearing them.
Right now I'm listening with the c5's & a dragonfly Dac & have the volume at about 5% which is why I'm leaning towards the 1-ohm version Regards David
