Halide Design DAC: $450 with captive (up to 7 meters long) USB (including power) and RCA cables, 24 bit/96 kHz, 2014 Stereophile Class A rated, tiny, cryogenically treated, simple (no display/control/drivers), asynchronous design, uses Gordon Rankin's (of Wavelength) Streamlength protocol to reduce jitter.
Sound: seductive/smooth, ease/purity, deep/agile bass, not dry/ruthless, delicacy with power, an ideal balance between resolution and tone, analog/organic, does a good job of imaging and expressing the original space, 2014 Stereophile Class A rated.
Paired with Adam F5 active 2-way stand-mounts (and throwing $50 in for interconnects) you'd have a very nice computer based system.
