An outstanding headphone amplifier and DAC — used as preamp/linestage it makes for a great desktop or home system.  This model was best used via USB, which supports up to 24-bit 192 kHz files. The headphone amplifier works really well and includes a cross-feed circuit (can be disabled via menu). Excellent entry-level product for building up a line-level system. Also included is an Audioquest Coffee USB A-B mini 1.5 m cable that uses the 72 V DBS system — sounds wonderful with this unit! Also includes remote control.

A few notes about this particular item:

  • balanced output requires connection is via 6.35 mm TRS jacks on the unit (not traditional XLR)
  • the USB input is via the “mini B” type connector (that’s why the AQ cable is included)
  • not sure how the optical input sounds — never used it
  • unbalanced headphones only

Included: generic 15 A IEC power cord, free USPS domestic shipping, owner’s manual (PDF via email on purchase), USB A-B mini w/ fresh DBS battery pack, original footers (not pictured)

Not Included: original packaging, remote control 9 V battery, interconnects
