FS: Teac UD-503 Dual Mono Balanced DAC/Amp + XLR4 Adapter

Price: 450
Currency: USD
Ships to: CONUS

For sale is a Teac UD-503 Dual Mono Balanced DAC and custom dual 6.3mm to XLR 4-pin balanced headphone adapter. The full specs for the UD-503 are:


Condition is near new condition and 100% functional. This is a great balanced DAC featuring AKM AK4490 DACs (one per channel), plus separate power for digital and analog circuits (10 lbs of power goodness!). I decided to downsize to a single interface with inputs since I use a mic (Adi-2 Pro FS, same internal DAC’s as this).

Included in the sale:

  • Teac UD-503 (Black)
  • Original power cable
  • Original remote w/ batteries
  • Original coax adaptor
  • Original box, packaging, and documents
  • Headphone Lounge custom dual 6.3mm to XLR 4-pin balanced adapter

Due to shipping weight (10 lbs), I am limiting the sale to CONUS or local pick-up (Bay Area, CA).

One example review I wholeheartedly agree with can be found here (rated better than Gumby!).




Please note, the remote has been taken out since pictures were taken, but still like new.



The 503 is pretty legit. There were several times I regretted selling mine.



thanks! It is a great unit, but downsizing my setup.
