Wavelength Cosecant Tube DAC--very good condition, rated 8/10 as I am the second owner. This Cosecant is very musical, yet uncolored with great tonality providing hours of non-fatiguing listening.
This is the Denominator version, hand-built by Gordon Rankin the inventor of Asynchronous USB. The DAC is ~ 3 years old but has had minimal use, ~500 hrs of total run time. Replacement NOS ECC 86 tubes are readily available at low cost (~$20). For updates, the unit can be sent to Gordon.
I will cover shipping costs and PayPal fees in CONUS. I don't have the original box, however, I will carefully pack and double box for shipping. Thanks for looking!
