We have developed an upgrade package which we call ‘The Paradox’ specific to the Sony SCD-1 , SCD-777es , SCD555es , XB-940qs and DVP-S9000es family of players. These players (all stereo only output) share similar audio chips and allow extraction of the audio signal at the earliest stage possible. SACD is extracted as the DSD bitstream without any conversion to PCM and redbook CD is extracted using Sony’s VC24 chip allowing user selectable digital filtering. Later Sony models integrated the digital to analogue process and do not upgrade to the same performance. We have developed a passive analogue output stage which bypasses the Sony voltage to current converter, current to voltage converter (yes that’s right they convert from and back to an analogue voltage signal !!!), Ultrasonic filter and output stage. Our passive stage reduces the components in the signal path to the minimum possible for the minimum degradation of the music signal, that’s the Paradox - less is more. Our passive stage is fully capable of driving into your amplifier via interconnects.

In addition The Paradox upgrade includes the Chevron UltraClock2, and many power supply improvements including a Tentlabs Shunt regulator.

Cost of The Paradox upgrade installed in your player is £450 unbalanced output or £510 balanced output.

We have experience servicing these players and can get essential spares so can support your upgraded player for many years happy listening.
