If I may chime in, I have the Open X, Closed X and Elegia. For $379 new on Adorama, the Elegia are the deal of a lifetime. I'd suggest the Elegia if you want a bigger, punchier sound. They are showty in the mids, but have the most impressive presentation and sound very wide and deep for being closed.
The Closed X sound amazing too, but I find them way too bright and bass-shy for my taste. The Open X weirdly sound less open, but punch twice as hard and are not as bright. Both are power hogs for being modern planars. They need big current to sound their best.
Though it's tiny, it manages to power even high ohm headsets with amazing accuracy. It works great with the drop usb-c to usb-c and my Phillips shp-9600. Soon enough I'll be using the Akoustyx...
I have an external amplifier with no integrated DAC and I only have an xduo xa10 as a dac/amp can I use the xduo xa10 as a dac only with an external amplifier?
So I bought the HD6xx a few weeks back and when I finally got the packages i got some Noir 99. ever happened to any of u guys and how did it get resolved
