For the most part, the dacs analog section is responsible for the qualities you list.I agree.
The Line Magnetic LM-502CA is a very highly regarded DAC, but lists for $1800 new.
Closer to your budget is a Schiit Multibit or the PS Audio DSD Nuwave. The Nuwave takes the native signal from your transport and has a passive analogue output. I'm auditioning one right now; very nice ($1299).
