I purchased this unit a little over two years ago from the manufacturer. It came with only a USB out. A year ago I sent it in for a serious software upgrade and the removal of the USB out, replacing it with an RCA coax output. It eliminated the installation of DAC drivers. This server does not contain a DAC, it must be connected to DAC using an RCA digital cable. There are no RCA/XLR analog outputs.
The unit is in excellent cosmetic condition and operates with no issues. This is one of the simplest media servers to operate requiring very little computer knowledge. If you can go to a website, type in a couple of passwords, do a few mouse clicks you have it mastered. It uses JRiver for library management, DBPoweramp for ripping (a 40-45 minute CD typically will rip in less than two minutes).
The server operates on WiFi eliminating the need to hardwire to a router. 2TB storage.
What makes this particular unit more valuable is the approximately 1800 discs that are on the hard drive. 365 different artists, about 1400 titles. Artists range from Aerosmith to Yes. Vast majority of titles are rock (I am 67 years old and I got hooked on music in the early 60s). Most artists on the unit started recording in the 60s and 70s. There are a sizeable number of female vocalists along with a smattering of country.
Easily $15,000 worth of music.
