The L-507u is a mid-range model delivering ample power of 200W rated output at 4Ω load. It is equipped with the upgraded ODNF version 3.0 as mainstay of the amplification section which governs sound quality. Low impedance achieved by error detection circuits has resulted in a greatly reduced distortion rate and improved signal-to-noise ratio, and the capacity to maintain a high initial slew rate – all of these characteristics work together to create a powerful and sophisticated musical portrait. With its built-in separation switch for separation of pre-amplifier and power sections, it is possible to add a power amplifier for bi-amplification and use the unit in combination with an AV system. True to its high-end image, the L-507u offers many attractive features such as copper alloy terminals, large size speaker terminals, and a hairline-finished aluminum top panel.
