Recommend a DAC for my system....please.

Hard for me to audition because I don't know where to start. I pretty much have the HT area covered, now I need a NICE musical dac somewhere around the $3k area. New or used. I was thinking about the Levinson 36/36s.
My listening taste depends on my mood, mostly jazz, bossa nova, pop, etc... but NO rap.
It'd be great if I can be satisfied with this dac for a long, long time. Any thoughts????

Much appreciated...
