Budget USB DAC


I'm looking for a budget USB DAC. Does anyone have any experience with Diyeden, Fubar II, or Keces? Are these worth looking at?

All I need is the USB port, and RCA outputs like the Scott Nixon and Wavelength units have. I can't afford that price range though.

Thanks for the replies. I saw the review on Stereo Link in the NY Times. I think they are backlogged because of that article.

Fubar II needs an external power supply? Guess I thought it was usb powered. I'll check out their web site again.

The Thingee sounds interesting for the price. I have surfed their web site before. Looks like you can config it the way you would like as far as connections.

I'll keep looking. Wish one of these would show up here on A'gon from someone that upgraded to a higher priced unit.
Once again - The Fubar II comes with a wall-wart power supply. It is not bus powered. The upgraded "Supplier" power supply improves the performance of the Fubar II.

I have used a stereo link, a fubar with power supply and an m=hdt paradesa. I like them all. If budget allows, id start with the fubar and work up....

I think hagtech sells a usb dac for cheap as a kit if you can build it...
The Hagerman DAC USB DAC, the Chime is pretty expensive, so I think Kbuzz is refering to the HagUSB, which is similar to the "Thingy" mentioned by Jwmazur and converts a USB signal into a digital signal that can be input to a DAC. In the case of the HagUSB, RCA Coax and AES/EBU outputs are available. Both devices still require a DAC.

I have a few systems and one uses a HagUSB into a Slimdevices Transporter's RCA Coax digital input.
The Blue Circle Thingee is on back order too. Just like the Stereo Link. Angela from BC linked me to a dealer in IL.

I've checked the Hagerman web site before. Forgot to mention them. I've built kits before Kbuzz .. a Dynaco 410 amp. No problem soldering but it has been a while.
