To Dac or not to Dac

I would look for DAC that also have USB. Past century DACs wouldn't make a sense to me nowdays, when I download several gigabytes of music every day and listen. I picked Mytek DSD, but in your case for lower budget I would look for Cambridge DACMagic special deals on sweetwater, b&h photo-video, fullcompas or similar pro-audio sites.

Tmsorosk,
As living techie I can tell that tube DACs are only for audiophile community. All they do is show glowing tubes inside the chassis. They've been placed on the output stage, but all we perfectly know that to make a computer processor out of tubes takes a space larger than fridge in your kitchen!
