You may want to look at Chord DACs. You can find them on the used market for under $1K. Now there is a person (Ross Martin) who builds DACs out of his house...a couple people i know really like the sound from his DACs. His website is rossmartinaudio.com. He uses the Burr Brown PCM 1794. Price under $800.00
If you are looking for cables....look at Clear Day Cables or Cullen Cables...well made nice prices.
