Luxman L-507uXII Integrated Amplifier
We say - Controlled bass and highs. Deep taut bass. Always transparent, musical, and smooth. Never, Never edgy or harsh. The phono amp is also a heavyweight.....Fantastic. So if you want an integrated that is versatile and absolutely true to the music.
To achieve such high levels of sound quality takes first of all a build quality that is the envy of the industry. Also experience - Luxman has worked with audiophiles and has always progressed - not rely on their past acclaim but by moving forward. In recent years Luxman has shone brightly and won awards wherever it went.
Here are some proprietary technologies used by Luxman;
Highly accurate Volume Control
Volume controls design impacts sound quality. As the volume is changed, the power amplifiers section "sees" a changing impedance and sound quality is affected. Volume controls also degrade over time. In the L-505 you will find a state-of-the-art solution.
LECUA (Luxman Electronically Controlled Ultimate Attenuator) is at the heart of the pre-amplifier section and the sound volume adjustment function of the L-507uXII. LECUA allows smooth and fine volume adjustment over 88 steps, thereby minimizing any deterioration of the audio signal. The multifunctional ability of LECUA ensures accuracy over the full range of the volume control, whilst suppressing any deterioration of sound quality.
Innovative amplification feedback circuit
In order to avoid distortion, amplifiers commonly use global negative feedback - a technique that reduces distortion but has negative side effects. Luxman overcomes this shortcoming as follows:
An integral part of the design of the L-505uXII is LUXMAN's original ODNF amplification feedback circuit featuring a high-speed primary slew rate, an ultra-wide bandwidth - achieved by feeding back only the distorted components of the audio from the amplifier's output circuit. Now, the gentlest audio signals are preserved and achieve a full range of dynamic musical expression.
Enhanced high capacity power supply
The higly stable power supply of the L-507uXll consists of a large capacity EI-core type power transformer and 4 pieces of customized 10,000 μF capacitor blocks. This ensures an instantaneous, constant and stable current that will exhaustively deliver sound dynamism.
Discrete buffer circuit
The L-507uXII features a new discrete, embedded buffer circuit mounted on the output stage of the pre-amplifier circuit that is equivalent to the type used in the high-end C-900u. This helps to protect the purity of the audio signal whilst enhancing the drive force of the power amplifier unit.
Low impedance transmission
Large-capacity, low resistance speaker relays are connected in parallel to enable lossless transmission for the powerful driving force that is generated by the large-scale output circuit. In addition, the damping factor has been improved from 205 to 260 by directly connecting to the speaker terminals thus enabling a dynamic sound expression.
Original technologies prioritize sound quality
To realise a smooth, stress free signal transmission LUXMAN use an original Beeline construction that is a non-angled wiring pattern to allow the signal transmission to take the shortest optimal route. This is one of many examples of a LUXMAN original design that makes sound quality a priority.
A wide variety of custom-made parts for high sound quality
OFC wires are used in the internal wiring of the L-507uXII to achieve a natural signal transmission due to the spiral wrap shielding on each core and non-plating process on the core wire. This model is generously equipped with many custom-made parts designed to achieve high sound quality such as Y lugs for a secure connection.
An abundance of user-friendly functions
The L-507uXII is equipped with a high-quality phono amplifier that is compatible with MM/MC cartridges. This model offers all the functions that a high-quality integrated amplifier should offer such as bass/treble tone control, LR balance adjustment using LECUA, pre/power separation function, volume function, and headphone output to name a few.
New customized gradation cast iron Insulator
Gradation cast iron legs that are used for the LUXMAN 900 series separate amplifier are fitted to eliminate resonance for the L-507uXII, taking thorough countermeasures against vibration. The solid loopless chassis with thorough grounding adds to the structural stability and therefore sound quality.
