For sale is my very lightly used Questyle CMA 12 Master DAC/Headphone amp in black.  Near mint physically and performs flawlessly.  Drives any headphones you may have via 4.4 mm  and XLR balanced well as 6.3 mm unbalanced connections.  Check out the Questyle website for specific details.

$1550 plus shipping but would prefer local pickup in the Washington, DC, Northern Virginia area.  Thanks for looking and ask any questions you may have and I will do my best to answer them.  Original packing included.

Regards,

Joe
