I've just upgraded to an Ensemble Thunderbolt, so I'm letting this interface go. Used in my home studio only, the Quartet is in perfect shape. It comes with the original box, manual and cables. NOW FOR WINDOWS TOO... the Quartet has always been a MAC only interface, but in the past few weeks Apogee has released a driver for Windows. See here for more details: Apogee For Windows 10 SOLD shipped w/PayPal. NO TRADES. Please note, I only ship CONUS.
