Schitt Bifrost VS PS Audio Digital Link 3

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.

I like Willies’ suggestion. The V-Link would also make an improvement over the PS DL3s’ USB interface. I have not heard the Schiit and could not have made his comparison. I have a V-link II USB/SPDIF converter which I use in a 2nd system. It is only 24/96 as opposed to the V-link192.  I purchased my V-link used for $70.
