A dedicated precision switching hub that brings the world of network audio into a completely different stage. Named as a precision network conditioner by high-end audiophiles, the M12 SWITCH PREMIUM is the successor of the M12 SWITCH GOLD. As a result of reviewing the design and implementing further vibration countermeasures, more durable parts are adopted in the M12 PREMIUM. You can feel the improvements over the previous model immediately.
