Dac recommendations for computer audio


I have recently made the decision to retire my Cal Audio Labs Alpha and Delta combo. I have purchased a new version of the Mac Mini to go Into my system that consists of Salk Sound HT2-TL speakers, an Audio Mirror T-61 preamp, and a Counterpoint NP100 hybrid amp. Now, I need to add a high performing Dac that will deliver an analog-like and organic presentation. The ability to deliver killer midrange with female vocals, a large soundstage and clearly defined instrument separation are must-haves. I am very new to the computer audio world and my head is spinning from trying to keep up with available Dacs in the market. This will be my only source, so I want to get it right. I have an affinity for tubes, but I will keep an open mind and consider SS Dacs that meet these qualifications. My budget is 3k and under. Thanks in advance for your assistance.

Balkan gives some great advice here....I'd like to add:

I agree toslink from Mac is excellent. I highly recommend you buy a glass cable however- the difference is not subtle. I like and use both the VanDenHul Optocoupler II and Wireworld glass cables.

For Dacs, I want to add that the MHDT Havana delivers what you describe, and really works well with the Mac Mini.
Danlib1 is correct. If you choose to use optical, get a good polished glass cable. The VanDenHul and WireWorld glass cables are excellent.
PS Audio Perfect Wave is 3k, 2k with a trade in. Many people here, including myself, enjoy theirs. John
I got off the DAC merry go round once I heard a Weiss DAC2 in my system. I owned a MHDT Paradesea, and the Weiss smokes it. 3k new @ Vintge King.
Wyred4Sound DAC2 is an excellent DAC, and has an asynchronous mode DAC input that accepts up to 24/192. This would be a terrific unit at 3x the price, even though I find it ugly.
