I am selling a UNIVERSAL AUDIO UAD2 SATELLITE TB3 QUAD. I received this as part of a promotion when I purchased a 6176 about two years ago. It was working without any problems until just now. It is no longer needed due to a system change. There are no noticeable scratches or stains. Included accessories are the power cable and the original box. As a bonus, I will also include an Anker Thunderbolt cable. If you need it, please take advantage of this opportunity!
