Looking for a DAC w/ balanced XLR line out, budget $1k

Actually there is one I can think of very close to 1k used.
Auralic Altair.

Not heard one but checks all the right boxes and seen a few of late around the $1100 to $1200 price right here and eBay.

If there's a network player with balanced line out and a decent built-in DAC I'd consider something like that as well.

That would be a Lumin D2.... But more like 2k, possibly a little lower but not much.

Of course moving on up you have the Ayre QB-9 but that is USB only.
OP, what input do you need?

PS Audio NuWave DAC.
It's a half size component and it does full 24/192 on coax, toslink and USB.
No display so not missing much by it being hidden.
However a front button is how you select the different inputs so you might still need to be able to access it.
Fully balanced XLR outputs as well as single ended RCA outputs.
Available used for $500 or less.
I paid $400 for mine.
