NAD C658 streaming DAC/preamp with DIRAC room correction

NAD C658 streaming DAC/preamp for sale.  This a great-sounding piece with tons of features, including BluOS streaming, a high-quality MM phono stage, and DIRAC room correction.  Comes with all original packaging, remote, and NAD microphone for DIRAC measurements.  I purchased the full DIRAC license, but I don't know if it's possible to transfer this to the buyer.  The limited license provides room correction in the bass region only, which is where DIRAC makes the biggest difference.

This is a great DAC/preamp all around but is most compelling for someone who wants to try out DSP room correction.  DIRAC made an incredible difference in my system.  I'm selling to upgrade to a much more expensive DAC/preamp and will never again be able to live without room correction.

The C658 is in great condition, with no blemishes that I can see. I'm the original owner.

Buyer pays shipping.  Shipping will be via USPS Priority Mail from a U.S.-government Diplomatic Post Office overseas.  Shipping is fully trackable and rates are about the same as domestic - ask for an exact quote.  Priority Mail to CONUS generally takes about 10-14 days.

Thanks for looking.
