The question posed was, What are the good DACs for under $1,000? I think when it comes to digital sound, what you want, first and foremost is accuracy. To a great extent, this would go for all source equipment.

If you want to color the sound of your source equipment with your preamp or amp, fine. But why not start with an accurate representation of the signal first? This approach will also yield a more controllable, consistent output across all your sources.

My philosophy, since you asked, is simple. Generally what I do is buy used equipment on the basis of specs and, to a lesser extent, reviews. I buy online, listen at home and if I'm not satisfied, I sell the equipment. YMMV.

Also, I am certainly not opposed to colored sound if that's what you like. The problem with the marketing of all high-end audio is that creating distinctions between various gear requires either added color, deviations from response curves, distortion or noise variation. If you start with clear and accurate you will always know what you are getting.
Kbarkamian: My bad.

I was thinking of the Musical Fidelity M1 DAC (from $699) as shown in the recent Audio Advisor catalog. The Rega DAC is on the next page.

C'mon Rega; Get with the XLR already!
I'm a DAC rookie, and want to get a DAC. I have a tube pre (Lamm LL2D) and tube amp (McIntosh MC275), would I still benefit from a tubed DAC? I am leaning towards SS DAC, but that's from pure speculation as I haven't tried any (BTW, can't audition around here...). Hopefully more experienced members can provide some guidance.

Thanks!
Chicago , you only stated half my question . The rest was , I was looking for added bass, if that is possible from a dac.
It appears to be silly to waste more energy on the "accuracy from specifications" nonsense.

Another DAC that comes to mind for <$1000 is the Sonic Frontiers SFD1 and 2 series. This is from the same time as the Processor 3 series which was highly received by many viewers.....and also used the UltraAnalog chip set. 8-)
