LUXMAN L-505u Blaster white: 225,750yen(July, 2007 release)
Champagne gold: 225,750yen(a limited color, the August, 2007 release)

Description
@
The Integrated Amplifier announced as an ultimate edition of L-505 series.

Only the distorted component was fed back from the output of the amplifying circuit, and the original amplification period circuitry ODNF which gained the speed and the super-wide band of the initial slew rate is adopted.
In L-505u, the latest version 2.2 which made the input stage parallel is adopted as power amplifier.

A mass (400VA) EI type power transformer and the conversion efficiency to direct current voltage have adopted the high Schottky barrier diode as a power-source part.
Moreover, multiple-contact-switch IC currently used as an Attenuator switchpoint of the volume control organization LECUA is new-carried at C-1000f which is a flag ship model of a preamplifier,A failure of the tone quality by going via an input switching circuitry is reduced, and the separation and the crosstalk property are improved.

The rigid high substrate made from a glass fiber is adopted as an original OFC wire and all the circuitry blocks at a power source and the signal system principal part, and also the custom-made part of the Luxman original which repeated the audition and was completed is adopted, and the improvement in a tone quality is aimed at.

The separate switchpoint is carried in the front panel and a separation of Puri and power is possible.

Two kinds of colour variations of the champagne gold (limited color) which shines to yellow with the Blaster white into whom a large-sized power meter shines blue occur.
