Has anyone ordered any tubes from Upscale Audio out of California? I'm looking to roll the tubes in my Van Alstine DAC and Preamp. Franks recommends swapping out the 6N1P tubes for some 6CG7's. The one's that I need art the Mazda/Brimer 6CG7's because these are the only ones that will fit without having to mod the top of the chassis. They are supposed to give more bottom end as well as a wide sound stage with more depth and detail.
