“The formulation of the problem is often more essential than its solution, which may be merely a matter of mathematical or experimental skill.” – Albert Einstein Designed to standardize connection with computer peripherals, USB interface enables both communication with peripherals and supply of electric power. Communication with external sound cards (DAC) via USB interface is not really

Reviews of high end equipment are never objective. Actually, the gurus of today’s high end audio scene reject aggressively all projects that contain even a slightest dose of objectivity.
