If you've got $1k to spend, you should really make it a point to hear the Rega DAC. I like it far better than what's been mentioned. I've owned one since January and am done looking for upgrades for a very long time.
It does a great job with jitter. I run my Apple TV gen 1, cable box, and XBox as transports, and everything sounds great. The ATV/DAC combo sounds far better than my Rega Apollo (as a standalone CDP) ever did. Not even close. I didn't get the chance to connect my Apollo as a transport though.
