Brinkmann Audio Nyquist MK II

I am selling Brinkmann’s Nyquist MK II DAC, as the original owner purchased 2 years ago. The DAC utilizes NOS Telefunken tubes for the output and gain stage edging it to the warmer side of top performance. Tube life is claimed to be 10,000 hours - there is about 75% of life left on the tubes. 
The DAC is assembled as three pieces; the DAC, a slab of granite that the DAC rests on and a power supply. Brinkmann created the power cable for the power supply and recommends using this but does not discourage after market cables, however, it does not recommend mechanical isolation between the granite and DAC - this chalks up as a savings.  
The top is a clear cover, and reveals a very nicely put together layout using a deep red colored circuit board. I rate this a very conservative 8, more like a 9 as there appears to be some very slight discoloration from heat, it's nothing major you really have to look at it, there are no scratches or dings. 
I am selling the unit as I am moving to a same brand spinner/dac.
