not yet, will update anything we can share with you guys.
I Highly doubt even pairing the X3 with a good amp will compete with the DX100. It's nice to dream though.
Let's be honest here the X3 is really not here for that purpose and to think otherwise is naive. And yeah I do very much enjoy using my DX100 with the UHA6 MKII (Op Amp 8610) in particular now since 1.2.7 firmware update (big upgrade in sound quality now & on par with my desktop rig). Before on 1.1.7 the T1 had better synergy. Still both amps perform very well with this unit. Not that it's a requirement by any means but I love being able to improve things further and while I'm not moving around much I'll be very apt to use a portable amp with it :). Now if the X3 could compete with my Studio V 3rd ANV or even Rocoo BA that would be something.
Never said that was naive as I agree it would be nice to have a device with a slim form factor with these inputs. I'm just saying thinking it will compare to a DX100 is hoping for too much. Not even saying that is coming from your mouth, just putting it out there. But indeed if this unit can compare to the Studio V in sound quality I'll be very much inclined to jump on it (personally I still think this maybe asking for too much but I can dream as well).
