Hi guys, and thanks for taking time to respond. I have already initiated a return via amazon.
I will purchase another unit to see if same problem exist.
I tried all sorts of files, picking from 63 gb or so of various content over the years.
I work as an audio engineer, and have been through the digital age since 1989, starting with Studer Dyaxis editing machines. I put in over 60hrs a week working with digital audio. That said, you never know, file formats change, OS's change, etc. Still to this day, after more than 25 years immersed in this stuff, I am learning every day.
I really wanted this unit because it was affordable, and it sounded pretty darn good, and I wanted something I could take anywhere and playback mixes on various real world systems, rather than relying on nothing but reference monitors, my B&W;s and my near fields. Plus, if it got trashed, we are talking $100 usd.
I appreciate the help, and I will post back when new unit comes.
