Recommend A New DAC Between $1000 and $2000

I am currently using an older Assemblage DAC 2.0 ( BB1702 R2R dac chip, CS8412 receiver, PMD100 filter) with many upgrade mods.  It sounds surprisingly good, but I am looking for something current and better sounding, with the following characteristics:

- Smooth, spacious, slightly warmish sound

- Smooth, non glaring, non etched higher registers (maybe sounding just a bit    rolled off, as in lacking strident edges)

- Great sound stage and depth

- Excellent resolution

- Generally natural sounding

... and at a price under $ 2000 if possible

Any ideas and / or personal experiences?

Thanks in advance!
