Crescendo Evolution 7A2 is 2 channel amplifier to drive 1 pair of speakers with 125 Watts of power and 1 piece of 4 ohm subwoofer with 350 Watts of power. This amplifier produces dynamic and natural sound. On top of that, the design is elegant with enlightened Crescendo logo.

Crescendo Evolution 7A2 utilizes high bias class AB design which is well known for its low distortion sound and yet save for small alternator car.

Some modern features of Evolution 7A2 as follows:

• Amplifier applies big filter capacitor to balance low and high pitch.
• Amplifier is supported with high quality components such as Toshiba transistor, International Rectifier mosfet, and Wima capacitor.
• Preamplifier utilizes terminated design like legendary home audio preamplifier.
