DEQX Premate Plus Preamp, DAC, Room Correction +extras

The Premate Plus is an incredibly useful unit that contains both a remote control preamp and a high end DAC, as well as the best digital room correction I have ever used. 
It has subwoofer integration, a sota USB input for computer/server-based music libraries, is Roon-ready and supports DLNA network streaming.
 It is ideal for use with the kind of loudspeakers almost all of us have - loudspeakers with conventional passive crossovers. The DEQX - supplied USB stick containing the "DEQX-Cal" installer, calibration file for the standard Dayton Audio mic and a PDF copy of the user manual are included as is the standard mic.  I have added the Earthworks M23 reference caliber microphone with calibration file converted to DEQX format ("INV") by the folks at DEQX and both are also included (I will not split up the hardware). The M23 calibration file is on a backup cd of the data on the DEQX USB stick. 
I found initial setup and room correction using the user manual a simple process. DEQX provides an in-room measurement and set up service as does, I believe, Nyal Mellor of Acoustic Sounds, but I don't know the cost.
The Premate Plus is a bargain as a preamp/DAC. The room correction and other functionalities are icing on the cake.
The DEQX has audiophile quality parts and performance.
I am the first owner and purchased the unit less than a year ago.
I am a long time DEQX user beginning with the PDC-2.6HD model back in 2004. DEQX transforms the sound quality of your system. My only reason for selling is unexpected early retirement (not all bad) with need to revert to a bare bones system in a small space. I recently found a used Playback Designs IPS-3 Integrated amp/DAC that simplifies my system. Someone will get a great preamp/DAC/Processor (the Premate Plus).
All reasonable offers considered.

I will pay for shipping. Lower 48 states only.
Thanks for looking!
