Regards,

I've personally tried a handful of DAC's in the $1k - $3k range, and by far, the best I've sampled is the North Star m192 mk2. I've sold all my other DAC's, this is the only one I own now. The soundstage is absolutely huge - real, 3D, holographic, whatever you want to call it, it feels like you're there. I love it.

FYI I'm using it with Decware Zen Torii mk3 and Tyler Acoustics Taylo Reference speakers.

Burson Conductor (Sabre 32 Dac) is a solid recommendation below 2k. It acts as a preamp-headphone amp too.

NAD M51 is one of the best value DACs out there right now. Not $2000 used, but $2000 new.

Ayre C7, if you can find somebody that will part with there's. It surpasses it's equally priced competitors and gives the best out there a run for there money.
It's a no brainer.
