Crescendo Audio Design

The OPA-1 module used in the Crescendo preamplifier is a discrete Class A operational amplifier. The first stage employs a low noise FET input. This is followed by a differential voltage gain section. The output is a high current, low output impedance voltage follower which is capable of driving the most demanding load. This results in a very open, fast and transparent sound stage.

Features

The Crescendo features a high resolution USB DAC input capable of data streams up to 192 kHz/24 Bits. This allows connection from a computer USB to stream music without the need to purchase additional hardware.

The Crescendo uses Wi-Fi remote control on Apple devices. This eliminates the line of site problems associated with IR remote controls.
