Sugden Audio -
Class "A" CD PLayer.
Fusion 21

The Fusion 21 is designed to compliment both the A21 and A21SE Signature integrated amplifiers.
Utilising a high speed transport mechanism and on board memory, the Fusion 21 is a technically advanced CD player.

To reduce Jitter and control errors during play back there is a dedicated transceiver circuit, this re-formats data prior to the digital to analogue converter.
A unique conversion method is employed without oversampling or filtering in the digital domain, instead we chose an analogue filter allowing a very wide bandwidth.

Important as technology is in the digital domain, the potential can only be realised if the analogue output is capable of producing a high quality sound.
The use of a Class "A" output stage and trans-impedance amplifier ensures superb sound.
A useful additional feature of the Fusion 21 is a digital input.
This allows the connection of an external source like a music streamer or AV component.

The new Fusion CD player is the result of nearly twenty five years of development of Sugden digital products.
Our latest player combines modern digital technology with unique Sugden design criteria’s dedicated to high quality audio performance.
The heart of the Fusion player is a precision ‘CD Engine’ comprising of a very accurate loader/laser assembly driven by custom software.
The interconnected front-end board (servo) is capable of short term data storage through its on board memory, made possible by the CD disc running at a higher speed than conventional CD mechanisms.
The buffered output from the servo is passed to a dedicated digital interface transceiver.
An external high quality master clock allows low Jitter recovery of S/PDIF through the high performance internal PLL. 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.
This method of signal processing has made both over sampling and digital filtering redundant.
The analogue signal from the DAC is then passes through a current to voltage converter (trans-impedance amplifier) using circuits chosen and developed specifically for their performance and sound quality.
To remove any serious audible noise produced in the digital domain, an analogue 55K post filter is incorporated prior to the signal reaching the final pure Class "A" analogue output stage.

To expand the possibilities of digital playback, the Fusion CD player is also capable of acting as a high quality stand-alone digital to analogue converter.
When in Standby mode the S/PDIF coaxial input is activated allowing replay of an externally connected digital source.
