The weak link (no pun) on the DL III is the usb input, it is not asynchronus. I believe this is why so many are for sale. It is however a very good DAC, having a robust power supply and analog output stage.
I have owned one and used it with a USB/SPDIF converter. If it had two coax inputs I might still own it as I also use a disc spinner. I have not compared it to the Bitfrost, however, if USB is primary I would go with the Bitfrost USB which can be found used at similar price.
