Best DAC/preamp for under $2K?

Anyone with experience with the BMC pure DAC?

A few more for your list:
NAD M51
Cambridge 851D
M2Tech Young DSD

Used PS Audio PerfectWave MKII. They've come down a decent amount since the DSD version came out. You can likely even get one w/ bridge for close to 2K so you can connect it directly to your router for streaming.

Is there anything up to $2500 that's substantially better? The wyred4sound SE?

Also you mention the m2Tech Young DSD. One review I read said the upper octaves were extremely enhanced and detailed, another said the sound was on the warm side sacrificing a bit of detail and control but very musical.

Has anyone heard the m2Tech?

Curious to know if it would be better to spend up to $2.5 on a new dac/pre or buy a used dac/pre around $1200 and augment it with something like Audiophelio 2 or a synchromesh.

The list of manufacturers making Dac/Preamps right now appear to be endless.
