How to choose a DAC?


I'm setting up a music server with my new MAC Book Pro, an Audio Refinement System with JM Labs speakers. I will be using Lossless storage format. I have a discriminating ear and am needing help to know how to differentiate between a $400 DAC and a $4000 DAC? My budget is less than $1,000. Any suggestions

The main thing of course is how the units sound. I wouldn't focus on jitter because by definition a DAC with a lot of jitter is going to sound crappy.

Agreed. A jittery DAC will sound crap.

However, you need to be aware that some DAC's require a clean low jitter incoming signal whilst others can handle large amounts of incoming jitter on the digital interface. In practice this means that a nice sounding DAC with poor jitter rejection may require a reclocker to perform optimally.
For a grand go for a PS Audio,Benchmark,Wavelength Brick.For 5-750$ theres about 5-6 good ones,For 1750$ theres the Bel Canto.YMMV,good luck,Bob
My humble thanks to the experts who have responded. Its been an education for me for sure. I've learned about features, benefits, cables, inputs and outputs and have some recommendations that I will now go looking for on the sight. Always exciting to go shopping!
