GS Astell&Kern A&futura SE180 with all 4 DAC Modules SEM 1/2/3/4 + original case (9/10 condition, original packaging and accessories)

What the difference between Garage Sale (GS) and normal items listed on www.mimic-audio.com? 

These are items taken in trade, or used for demos, or are opened returns, or dead stock in 9/10 or better condition(unless otherwise noted)!  This is the first annual Garage Sale that aims to lighten the shelves in preparation for refilling with new, updated items in the coming year!
