Here is an unsolisited, and I hope, valuable observation of the external digital clock. I own the Esoteric P-03 D-03 transport dac combo. I recently purchased the G-0s clock, as good, no, as spectacular as this combo is, the G-0s clock made, what I call, a massively subtle leap foward, in it's sonic performance. I called several dealers to assertain whether or not power cords made a difference with the clock, I understand that with most components good powercords are essential. Not one of those contacted could give me a definative answer concerning this strange animal, the clock. Basicaly, they did general thought's kind of talk, clearly not based upon experience. By saying these things, I do not mean to disrespect or show rudeness to our much needed and appreciated dealers, most of whom are under the gun.Hence, I took it upon myself to experiment. Using graduated cords. In this order. Stock, at least it powered it up, then The wonderful $50.00 blue pc from GTT audio, MUCH better, then the fantastic Isoclean super focus ($1800.00), extremely good, Then I went to the Isoclean Supreme focus ($4,000.00),astro stellar. (ASTRO STELLAR)? So, I find that cords do make a significant difference with digital clocks. You can go as high as you like, especially with an extreme machine like the Esoteric G-0s. And of course, taking into account the resolution of one's system. Just for general information, I use the magico reference speaker, powered by eight acoustic reality monoblocks. six of which are the thauma turge's and one set of ear 1001 with a special 2.5 uprade for the bass. my pre-amp Is the Supratek Sauvignon. This review is not to start a controversy, nor in fighting, just an attempt to address a seldom addressed issue and in my humble way to help our small community. HAPPY HOLLIDAY'S, and good on ya.
