We recently upgraded a customer's Cambridge 840C using the basic mod program we've developed for the Cambridge 550C -
and then taking that program several steps forward. Most notably, the increased headroom of the 840C chassis affords
us the space to install a more effective vibration-draining mount for the large toroidal power transformer and to
significantly upgrade the vibration control mounting of the disc transport.
Our extensive internal upgrades combined with our top-of-line Clearview AC power cord and heavy brass footers unleashed
newfound bass articulation, treble clarity, and nuanced midrange detail from our customer's beloved 840C -- both as a stand alone CD player and as a DAC for computer or music server files.
Our full mod package for the 840C includes:
• threaded 2" Triplepoints integrated into the chassis
• Clearview Double Helix Mk 2 Plus AC Cord; choose 4-1/2' or 6' length
• upgraded internal grounds/wiring/capacitors/fuses
• upgraded power supply filtration
• improved vibration control mounts for disc transport and power supply transformer
• cryogenic treatment of all chip, circuit and power supply components
For customers who already own the 840C, our upgrade package is the best way we know to significantly improve the sound of your system from the lowest bass to the airiest treble--without the major investment required for a new component. Before ordering our 840C upgrade package, please call us toll-free at 1-888-236-2753 to schedule delivery of your component for
