Helaas geen originele doos meer aanwezig. Uiteraard wel een handleiding en originele afstandsbediening.
1 - Power supply
A toroidal transformer is used with secondary dedicated stages: one to the Analog/DAC section power supply and other two dedicated to the digital power supply. The analog power supply has been realized using all Audio Analogues strategies to reduce any interference and kill the noise in every part of the unit. Regulation stages have been placed in every sensitive circuit point and the bypass capacitors have been chosen not only for their electric performance but also after long and careful listening sessions.
2 - CD Mechanism
The Crescendo CD Player, like all the Audio Analogue CD Players, is mounted with the Teac CD-5010A, a mechanism specifically designed for high end audio applications. This CD Mechanism is very sturdy and has a very low Jitter output. The best starting point for a very high performance player!
3 - DA section
A complete 24bit/192KHz DAC chain has been implemented. All our experience and technology has been widely used. We have especially focused on the bypassing of the power supply, the decoupling of the DAC outputs and we have worked on a perfect separation between analog and digital circuits, with particular attention paid to the ground return path separation.
4 - Output Stage
In this product Audio Analogue has placed a lot of focus on the output stage and a new approach to the design has been developed. We have realized a fourth order active output filter that, together with the inner one pole filter inside the used DAC, forms a fifth order output one. Such a high order (usually found only in really very expensive products!) has permitted us to increase the cut off frequency of the output filter with excellent results on the audio performance of the unit, especially for the increased precision of the listening stage. The problem of the approach (and thats why it is usually implemented in high price products) is the added distortion and noise due to the high number of stages the sound has to pass through. Audio Analogue has used all its experience and technology to design every part of the stage and choose every passive component to reduce, after long endeavours, the overall distortion and noise with absolutely astonishing results!
5 - Trigger In/Out
The Crescendo CD Player has both the Trigger in, through which the unit can be turned on by another unit in the chain and a Trigger out, which can be used to turn on an external unit.
