Reviews
"it sounds purposeful and powerful, displaying the ‘grunt’ expected of a flagship while bringing grip and depth to percussion and basslines. This solidity continues all through the audioband, for a listening experience possessing plenty of body and heft"
"the amp’s handling of the piano samples, and that driving rhythm, elevated the track to almost hypnotic status"
