[High end, battery operated, NOS and very analog DAC. Highly regarded, lots of online reviews.
In new condition was used 2 months and was in the box for 8 months more.
Includes the Ultra-Resolution Option, digital cable and interconnect that that were designed and build by the Ack designer for perfect synergy.
Works great with Monarchy Audio DIP Classic (also offered for sale – 8 months old).
