DAC's for the money?

Hi all,
Having been working for about two years now on my system, which has graduated from entry-level Sony/Inifnity to Rotel, Pio Elite, Infinity Kappas, and a partridge in a pear tree, I am seriously looking to upgrade my digital playback.
I have the Elite DV-47ai player, which I have run for both high-res stereo and digital direct to my processor (Rotel RSP-1068.) I have a Philips burner deck laying about, and am using that as a budget transport (student here!) directly to the processor also.
I have become convinced that I should purchase a good, relatively inexpensive DAC as a way to greatly improve my CD performance. I am after the Musical Fidelity A3.24, which I can get here on the 'Gon for about $650 +-.
Are there any other DACs that can offer me the same level of performance for about the same price? If I had my druthers, I's be able to purchase the MF Tri-Vista series, both SACD and DAC, but, as I am getting ready for graduate school, the cash just ain't there!
AM I on the right track with the A3 24, or should I consider others?

Thanks for imparting any wisdom!

Cheers.
