I was fortunate enough to get one of the nicest reclockers, the Titans Audio Helen (Japan) to do some mods on, so of course I made some jitter measurements. Helen is one of the few reclockers with I2S in and out.http://www.titansaudiolab.com/en/products/Helen/Helen_guige.html
They advertise "residual" phase jitter at 2psec.
I also measured jitter on the Synchro-Mesh again, this time with the new upgraded oscillator. Both using S/PDIF in and out and same cabling. BTW, the Helen is $1700 with wall-wart. The Synchro-Mesh by comparison is $699, less than half, but I used the $800 LPS for this, so $1500, but mine has LPS, not wall-wart like the Helen.
Titans Helen jitter distribution:
Synchro-Mesh jitter distribution:
Helen has more like 60psec of jitter based on these measeurements, not 2psec. Synchro-Mesh has ~1/6 of the jitter of the Helen at ~10psec.
Titans Helen spectra:
Synchro-Mesh spectra is an order of magnitude lower in amplitude across the spectrum.
