Special capacitors and inductors have been carefully selected for the digital amplifier’s LC filter, which is essential for achieving highresolution audio. These high-performance parts reduce noise and distortion and ensure excellent sound quality.


By using superior technologies, the Kenwood eXcelon XR601-1 generates high-quality sound and powerful bass, while still being compact.


The feedback value of the current XR Amplifier has been optimized to improve the S/N ratio. As a result, the noise level has been reduced by up to 40%.
