CRESCENDO AMP by AIRTECH Pris 11500:-
INTEGRATED AMPLIFIER Pris 11500:-
Crescendo AMP by AIRTECH has on output power of 50W on a 8Ohm impedance and 80W on a 4Ohm impedance with a THD+N of less then 0.05%. The SNR is more than 100dB and the band-width more than 150KHz. Crescendo AMP by AIRTECH is a High End product in all its parts. The cooperation with AIRTECH has helped to make a unique a products that was already very good: the changes and technologies used in some key points of the circuit are mainly related to the wiring, cables used are 7N OCC in pure copper, the same used for the production of AIRTECH cables, adding Wima capacitors for better filtering and decoupling of the states. These changes effectively allow a significant improvement of sound performance on all parameters and mainly in micro detail and the three-dimensionality of the sound stage. The sound is more open, listening is more pleasant, never tiring thanks to better ”musicality”.
The Crescendo AMP by AIRTECH has also been designed to be really very versatile:
• It has 5 Line Inputs and a frontal input to be connected to a portable player. It also has a REC Out and a Phone Out.
• The LINE Input 5 can be configured in By-Pass mode to easily place the Crescendo AMP by AIRTECH in an audio video system, in such a configuration the Crescendo AMP by AIRTECH can drive the front loudspeaker, which can easily be shared between the Stereo-System and the Audio/Video-System increasing also the overall Audio/Video audio quality.
• It is possible to choose the volume scale to perfectly match it to the loudspeakers’ sensibility. 4 different scales are available, 3 of them have been designed for different loudspeakers’ sensibility and the last with 79 steps, 1dB each, for the most precise scale at all, if required.
• Balance function.
CRESCENDO CDP by AIRTECH
The Crescendo CDP by AIRTECH comes from a deep research in which it was decided to implement technologies previously used only in High-End reference products. The CD-mechanism used is the CD-5010B specifically designed by Teac for high quality audio applications. The CD-5010B has been developed starting from a CD Rom base, reducing its speed of rotation in order to avoid mechanical vibrations. The reading process has been improved by reducing in particular the contribution of jitter.
The DA conversion circuit is composed of a 192KHz/24Bit ”very low recovered system clock” Burr Brown receiver (Jitter residue of 50ps!) and a 192KHz/24Bit Burr Brown DAC with Enhanced Multilevel Delta Sigma architecture.
In this product Audio Analogue has focused heavily on the output stage where it was decided to undertake a new project line. We made a fourth order active filter, along with the single-pole filter inside the DAC, it forms a fifth order filter. Such high order filtering allows to choose ”freely” the cut-off frequency of the filter output with excellent results in performance especially with regard to the definition of the music scene. The problem with this approach is the increase of distortion and noise due to the number of stages that must be passed by the music signal, problem solved thanks to the experience of Audio Analogue and meticulous choice of each passive component in order to reduce the overall distortion and noise with a surprising result, further developed through collaboration with AIRTECH that makes unique something already very good: the changes and technologies used in some key points of the circuit mainly concern the wiring, using pure 7N OCC copper cables, the same used for the production of AIRTECH cables, adding Wima and Sonicap capacitors for better filtering and decoupling of the stages. These changes effectively allow a significant improvement of sound performance on all parameters and mainly in micro-detail and the three-dimensionality of the sound stage. The sound is more open, listening is more pleasant, never tiring thanks to better ”musicality.
