“The Sigmas allowed two different systems – a friend’s and mine – to perform as if the electronics had been upgraded rather than the cables. Everything sounded clearer, more coherent, and more dynamically alive. The noise floor dropped dramatically, so fine details and timbral qualities emerged much more readily. Instruments and voices had more body and depth. The overall soundscape expanded in all directions and became more continuously layered from front to back.”
