LUXMAN has been at the forefront of integrated amplifier design since releasing the first Japanease integrated amplifier, the SQ5A, in 1961.For over 50 years, LUXMAN has been confronting the challenges of balancing performance, function and design in an integrated amplifier body. These years of research and experience have resulted in the L-590AXII, the ultimate complete integrated amplifier design.With unprecedented spatial expression – and a sense of density particular to Class A design – outstanding realisation of tonal quality and penetrating audio ability have been achieved in this Class A integrated amplifier.The integrated L-590AXII introduces a combination of high grade technologies found in LUXMAN separate amplifiers, such as the original amplification feedback circuit ODNF4.0, LR independent block capacitors, discrete configured buffer circuits and the newly developed LECUA 1000.The L-590AXII is the peak of integrated amplifier design, amalgamating tried and tested know how and state of the art technology.The L-590AXII is the debut flagship model of integrated amplifier from LUXMAN to commemorate the 90th anniversary of this ground-breaking company.
The newly developed integral LECUA1000 computerized attenuator with an 88 step amplifier circuit has been mounted in the volume adjustment unit, that is, for the first time as LUXMAN’s integrated amplifier, an essential part of the pre-amplifier circuit. This pre-amplifier circuit uses the same design as the top end control amplifier, the C-900u. The LECUA 1000 enables the sound volume to be adjusted smoothly with minimal deterioration of sound quality. A 3D layout has been introduced in the LECUA 1000 that allows substrates to be placed in three dimensions with the attenuator circuit directly connected to the amplification circuit, thereby minimizing routes and improving efficiency. Furthermore, this type of layout is extremely insensitive to external vibration and changes in sound quality caused by the volume level and has high durability.
