WHAT ABOUT CLOCKS?

If using an outboard clock on a DAC makes it sound better, then somethng was broken or they didn't design it correctly to begin with.

I am using a brand new dac and clock. Neither are broken. I have read your favorite dac mps-5, which with usb has only a maximum 48khz. I use usb. My debussy usb does considerly better. I know of "playback desighn's" y and x axis theory. I have read where "playback" sees the clock as "at best a fix". Dcs has no clue about what they design. My dac and clock cost no more then you favorite Mps-5, but I believe mine does more and does it better, for certain usb. Which is what I use. If this is broken, I would LOVE to hear fixed. Either way, it sounds fantastic. Clock and all!

I CAN'T BELIEVE IT'S DIGITAL!

I just added an Esoteric G25U to my Esoteric X03SE. I am still evaluating but it does appear to be a positive effect. The real plus for me, though, is that the G25U is also an upsampler (up to 192/24) so I am upsampling my SB Touch with the G25U and sending a 176k signal into my Berkeley DAC. (Playing with 196k as well). The soundstage is much, much deeper and I have a nice layering of soundstage, which is also wider. Much larger presentation, more palpable. Just amazing. The digital sounds incredibly good.

I auditioned the GOrb for 2 weeks intensely with my new Esoteric K01 player (an absolutley superb CD player). The K01 sounds exactly the same with and without the GOrb. The GOrb will improve the sound of 2 box players (like the Esoteric P03/D03), because it synchronizes the transport and DAC clocks on one superb external clock. It will not improve the sonics of a one box player unless the player has a lousy clock. The K01 clock is very good (accurate up to 0.5PPM). The X01D2 (my old player) clock is not quite as accurate as the K01(I can't remember the exact spec on the X01d2 clock, I think it is around 1.0 PPM). I doubt that there will be a significant detectable audible improvement by adding the GOrb to the X01d2. There is no question the clock will be more accurate but the X01d2 transport and DAC run off of the same internal clock, so it is already synchronized. The improved clocking accuracy, under the circumstances, will not be audible, in my opinion.
I suggest you try the GOrb before you buy. It is a very cool piece of equipment. But, it is quite expensive. It didn't do a thing for the K01.
I think your money would be better spent by trading in the X01d2 for the K01, the improvement in sound is enormous.
Good luck!
