Purchased brand new in January 2019 from an Apogee-authorized reseller. Reason for selling is that I am transitioning my professional-quality home-project studio, and all related equipment, into a downsized, portable, mobile setup. Converter has seen somewhere in-between 10-20 hours of use. Mostly to create preliminary mixes / masters via the headphone output and track vocals and acoustic guitar when needed. Otherwise, it has just sat nicely packaged in its original materials and box. Money was no object at the time of purchase and I wanted a converter that had the best dynamic range available in terms of tracking/mixing/mastering. Unit is in mint condition and the original plastic protective covering over the color display has never been removed. Always used in a smoke-free and temperature / light-controlled environment. When not in use it has been safely stored in its original box and packaging. Everything (box / packaging material / power cable / documentation) that came with the original unit was safely stored / retained, and will be passed onto the buyer. I treat all my gear like precious jewelry (especially anything Apogee-related). Contact me only if you are serious about purchasing. I am happy to answer any questions that you may have about this unit for sale that I have not already addressed, but I am not open / available to answering general questions about this unit that can be answered by a relatively simple internet search. Not open to tire-kickers, scammers, trades, wishy-washiness, payment schedules, or flakiness. I appreciate you looking at my ad and hope to hear from some of you soon! I apologize for not capturing a shot of the rear panel when snapping photos. I am not sure how I missed that. But I uploaded a generic picture for your reference. I 100% promise you there is no fishiness about the configuration or condition of the rear panel. It is for the Thunderbolt connection and it too is mint. You can meet me in person and pick-up the unit at my home in Novato that is conveniently located not too far from the freeway. Price is more than fair and non-negotiable. New these are $3500. Consider this unit “like-new”.
