"The Superclock 4 upgrade has indeed bettered by expectations....please let me know when the phase 2 is available...I don't think I could part with my CD23T for a while yet, at least until I've been through my CD collection a few times"
“The improvements wrought by the Superclock 4 over the Superclock 3 were not subtle...if you are currently using Superclock 3, do not hesitate for a minute to upgrade to Superclock 4."
