Viola Audio Crescendo preamplifier
















































$22000

Aluminum monocoque chassis
Housing adopt new unibody structure that has been carefully carved from a solid block of aluminum to aerospace grade. A significant impact in the electrical shielding, maximize the performance of the internal circuit damping, and radiation efficiency.

OPA-1 module newly developed
OPA-1 module was developed for CRESCENDO configuration is completely discrete. Input stage has adopted the input FET that features a low noise, wide. Strong high current, low-impedance output stage design to the load. As a result, we have achieved a sound with a high-speed, open and transparent feeling.

1MΩ
VIOLA product so that all of it is, the input impedance is set to 1MΩ. Is guaranteed with stable operation without being shaken to the impedance of the source device, I pulled out to its full potential.

Built-in USB DAC
with a high-performance USB DAC supports up to 24bit/192kHz. You can be wired directly to the CRESCENDO and PC, enjoy the high-resolution sound.
