I just completed a modification of my SCD-1 with the Audiocom Superclock3/PSU3 upgrade by Reference Audio Mods.
The sonic improvements are superlative. the sound is much more analog-like (smoother more relaxed) with great retreival of detail, especially spatial cues and better definition across the audio spectrum. The upgraded SCD-1 closes the gap with my Oracle Delphi MKV SE, Graham Phantom tonearm and Helikon cartridge. The upgrade is a no-brainer. The only issue is the long term reliabilty of the clock.
