Description
XA8800MNu is a mono power amplifier pair, with full symmetric current negative feedback structure.
This model offers the user superlative high-quality sound reproduction along with quite beautiful and elegant styling.
The amplifying circuitry design follows the well appraised current negative feedback structure, featuring the full symmetric and full complementary circuit.
The most outstanding advantages of this circuitry are the powerful drive, low distortion, rich dynamics, excellent control, exceptional reliability and a quite stunning sound.
The whole amplifying circuitry can be divided into three stages: the first stage adopts quality Motorola MJE350/MJE340 geminate transistors, the second stage adopts Toshiba 2SC517/2SA1930 geminate transistors and the output stage uses three pair of Sanken 2SC3264/2SA1295 high current geminate transistors.
Therefore, this amplifier is endowed with comsummate power when driving the highest current demands.
The materials are very select and of very high quality, especially some audio-use-only and world famous capacitors are used in the audio loop. It uses silver-reed relays to switch the coaxial channel and balanced channel.
The whole power supply system is consisted of the 350W high quality annular transformer as the core, the 50A high speed bridge rectifier and 60,000 uF Rubycon capacitance. The power supply for voltage amplifying is supplied by the filtered and rectified separate windings of the transformer, which have high speed, low noise, low impedance and an unbelievably strong shielding ability.
Besides this incredibly high end design, the separate design of the two windings can rapidly reduce the intermodulation disturbance and thus increase the purity of the sound.
