I had a Superclock 3 installed by RAM in my CEC TL-1X transport as part of an overall upgrade. (See RAM website for full description.) I cannot tell whether it was the Superclock or the other mods or the combo, but there was a dramatic improvement in performance: tightended CEC's sometimes loose bass; better and more sparkling treble; wider and deeper soundstage and blacker background.
