Digital Drive Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it. |

The Pace-Car reclocker is inside my Spoiler DAC. Demoed it at THE Show two weeks ago.
Besides, if you have an I2S interface on the DAC, it does not matter that the "pull" reclocker is in a separate box. I use I2S cables about 3" long. It's actually better than traces on a circuit board. Each signal has its own twisted pair or coax. No ground-return sharing or crosstalk. Totally separate power supplies - can be battery. No advantage to putting it in the same box as the DAC.
