Purchased for my office system when my Mcintosh integrated was initially delayed and then showed up about 3 weeks later. Asking $695 OBO

As you can see in the pictures, most, if not all the accessories/manuals/etc. are still sealed as original. This literally sat in my rack for about 17 days before getting boxed up when the Mac showed up.

I have and will include the receipt from the authorized dealer showing a Thanksgiving 2017 ship date.

Some specs from the TEAC site: http://www.teac.com/product/ud-503/overview/

USB DAC that supports 11.2MHz DSD and 384kHz/32-bit PCM
Dual-monaural circuit structure used from the power supply to the digital and analog sections
Both left and right channels have their own high-end AK4490 DACs, which are made by Asahi Kasei Microdevices Corporation
Two high-capacity toroidal core power transformers—one each for left and right channels
Isolation circuit that completely separates the digital and analog sections electrically
4 TEAC HCLD buffer amplifiers, which are current-enhancing output buffer circuits, are used for the line amplifiers
Up-conversion to formats up to 12.2MHz DSD and 384kHz/32-bit PCM using an FPGA (programmable IC) that utilizes a fluency function
Two types of DSD filter and four types of PCM digital filter, as well as an OFF mode
10MHz external clock input supported (available during USB asynchronous transmission)
Two high-precision internal clocks—one each dedicated to 44.1kHz and 48kHz signals (available during USB asynchronous transmission)
One pair of RCA analog unbalanced inputs
Volume output can be set to fixed, fixed +6dB or variable for the one pair of XLR analog balanced outputs and one pair of RCA analog unbalanced outputs
XLR jack polarity can be set (2 HOT or 3 HOT)
TEAC QVCS high-precision volume circuit
Large digital volume display with excellent visibility and remote control with one-button operation of various functions
OELD display shows input signal type and various settings (with 3-level dimmer and off functions)
Fully-balanced drive headphone amplifier with discrete construction and maximum output of 700 mW + 700 mW
Headphone amplifier can be switched among 3 drive types: unbalanced, balanced and active ground
Digital inputs on the back include one USB, one coaxial and one optical
Combined coaxial mini/optical mini digital input connector on front is convenient for digital input from portable devices
Low power consumption design and automatic power saving function meet modern expectations
The full-metal body realizes both vibration control and elegant style in an A4-size body that enables placement on a desktop
TEAC original design for three-point support using pinpoint feet with attached bases
Compliant with RoHS
MSRP: $1000

Local pickup in the Washington, DC metro area or insured shipping is available at the buyer's expense.

Cashier's check/wire transfer/check (must clear) or Paypal O.K. (buyer responsible for fee). Trusted seller, see my reviews here and on Audiogon, USAudiomart, Ebay, etc. Contact me with any questions.

Thanks for looking!
