$1k is a hard "stop" in the world of DAC's. I found that once you're willing to hit the $1300-$1500 the sound is truely three time better in detail and bass. It's one of the few times in audio that the law of diminishing returns isn't true.
The Electrocompaniet ECD-1 and Audio Logic units are prime examples.
