This setup supports Super High Gain Mode, pushing a whopping 1000mW+1000mW per channel, ideal for driving high-impedance headphones straight from your pocket.  Superior amplification with THX AAA 78+ Building on the success of previous models, the M23 incorporates the THX AAA 78+ amplifier design for even greater audio output with high fidelity. This advanced amplification design provides truly balanced 8-channel parallel amplification that prevents crosstalk and promotes crystal-clear output.  Independent power supplies The M23 features four separate power supplies for its digital and analog components.
