The Audible Illusions Modulus L2 was an instant success and earned critical acclaim for its transparent and natural sound quality. Build quality is superb, with low-noise resistors and top shelf caps. The Modulus L2 quickly gained a reputation as one of the best preamplifiers of its time and has since become a highly regarded and sought-after piece of audio equipment by many audiophiles and audio enthusiasts.
