Depends which SB you are talking about, but the DAC's within SB's generically are not excessively jitter-prone. Fixing jitter is not simply a matter of replacing the DAC clock and/or transport clock with better clocks (although that is certainly possible - it just doesn't fix the problem). If you are using an external DAC, the only cast-iron way to remove jitter is to use the DAC clock to drive the transport. This usually requires mods to both the SB and DAC. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
