The Sugden Fusion 21 can be partnered with the Sugden Mystro
Integrated Amplifier, Sugden A21a Series 2 Pure Class ‘A’ Integrated Amplifier
and Sugden A21SE Pure Class ‘A’ Integrated Amplifier. The Sugden Masterclass PDT-4F partners the Sugden
Masterclass Pure Class ‘A’ amplifier series.
At the heart of the players is a precision loader/laser
assembly usually found in a Digital Versatile Disc (DVD) player and driven by
custom software designed by Sugden. The
laser assembly spins at twice the speed of normal CD transports enabling the
reading of the disc several times and calculating the original values from the
data. The interconnected front-end servo
board has a short-term data cache, which stores the signals and clocks them out
with quartz accuracy.
The buffered output from the servo is passed to a
dedicated digital interface transceiver. The transceiver is also able to clean up
(de-jitter) the received digital audio signals. The data signal is
re-formatted and the output status bits are selected before being sent to the
multi-bit digital to analogue converter.
The new set-up eliminates the use of steep-edged filters that
radically eliminate frequencies above 20 kHz as well as other side effects. Sony/Philips patented compact disc player
loader/laser assemblies previously used by Sugden required these filters. That is why without the filters and the
extended frequency ranges the players performance is equal, or better than,
quality analogue LP turntables.
