What tube for a Sigma dac?


Looking for suggestions on which tube to use in my Sigma 24/96 dac. My system:Sony 7700 dvd, CAL Sigma 24/96 dac, Morrison pre, Odyssey amp, and Magnepan mmg's. Someone mentioned a Raytheon nos 5751 or a Mullard nos 12ax7. Current tube is a Ruby 12ax7. Regards, Brad

I tried a Mullard CV 4004 for a while and then switched to a Brimar. Both came from Kevin at Upscale. I liked the Brimar better but ended up switching back to my older 16 bit CAL Sigma for personal reasons. Even though the 24 bit Sigma II was much more open and detailed sounding, i really prefered the much warmer sound of the original design. Stictly a "personal taste" and "system" issue as i know others that think that the earlier version is WAY dark sounding. While i've got an EVS Millenium II on order, i've got another CAL Alpha coming in next week to hold me over. I'd still like to find another killer deal on an ARC DAC 3. As to the "member" that thought tubes in a DAC were ridiculous, all i can say is, YOUR LOSS. You've NEVER heard "music" come from a CD until you've heard a good tube based digital system. You might have heard a lot of "detailed sound" come from a CD, but never "music". I didn't believe it either, but first hand experience taught the "science" and "common sense" in me a lesson on this one. Open your ears to a whole new world and enjoy your system instead of analyzing it. Sean
