Call Kevin Deal at upscale audio. He should be able to point you in the right direction. I believe he prefers the Mullard tube. http://www.upscaleaudio.com/index-2.htm
c-j Premier 9 DAC and 6GK5's tubes.
c-j Premier 9 DAC uses a pair of 6GK5, apparently preffered by the manufacturer, as it has been used in many of their amps and preamps. As the tubes are overdue ( after 3 years ) and I'm looking for replacements, I'm wondering if somebody out there could advice me on: going for the original Sylvania tubes or... GE, Telefunken, RCA, russian, chinese, chech... I would also apreciate opinions from present or former owners of this DAC.I use c-j DR1 transport and the DAC feeds directly into a pair of Bryston 7B-st monos. The speakers are Apogee Scintillas, by amped by Symo cables. Power conditioners are Chang 3200 and power cords are XLO's Pro's.
