Help me buy my next DAC


I currently have Musical Fidelity V-Dac/2. I'm looking to upgrade and these are on my short list. My needs in a DAC are playing internet radio from my computer to my main audio setup. Also playing digital music from my hard drive. Here is my short list: Wadia 151 Power Dac Mini- Musical Fidelity M1 DAC- Sim Audio 100D DAC- Emotiva Stealth DAC

Any and all help would be truly appreciated. All recommendations would also be appreciated.

The rotel RDD-1580 DAC just got a pretty over the top rave review by TAS.
Sells for just $800 brand new and looks like a million bucks. In the under $1k range I'd be looking at that.

If you step up to $3k-ish I'd be looking at the new femto wyred4sound DAC2se or the auralic vega.
Hi Krelldog
I have the Sim Audio Moon 100D. I probably won't be much help. I think it is a fantastic dac. I have compared it to the Sim Audio Moon 300D V2 with about 200 hours on it, which is a really great dac. Also with a NAD M51 with about 150 hrs on it. In my system the 100D is a little different but 95% of the 300D V2 and the M51 for musicality. I use a CD transport, and so no computer or internet radio. I do think the 100D would not shine quite as well in a thin or bright sounding system as it would in a neutral to slightly warm system. But that is not a big if just a small one. Please don't put to much emphasis on my post. I do think I have a extremely good, musical, natural sounding system and the 100D dac contributes to that.
What type of files on the hard drive? What do you play them through? For internet radio the V-DAc serves just fine.
Thanks for all the above replies.

Needfreestuff- The Meitner is way out of my price range...but thanks for the offer.

Just to clarify...Most of the DAC's I listed were above the 1K price point and now being heavily discounted in the 5-600 range. The files I need converting are the typical cd's I burned to my hard drive or mp3's. I also enjoy listening to Pandora and Sirious/XM. I don't neccesarily need it to be a pre amp...but if it does it would be a bonus. I'm really just looking to get the best bang for your buck DAC in the above stated price range (500-600)

Thanks again for any and all suggestions.
