I have owned this Audio Research DAC8 for almost a year. It is a very good DAC. It will work with both a transport and a computer using USB. It does great high- res with Audio Research's latest driver. You will want to download the latest driver from Audio Research's web site.
I have had many questions. The unit is just freshly back from Audio Research with the newer version of the USB board. It is in like new condition just checked by Audio Research. The original power cord, manual, and remote is included.
I am not considering low bids as I feel this unit is in like new condition and reasonably priced as is.
