The front hides most its knobs and controls behind a drop-down panel whereas the LA leaves them unconcealed. The two pairs of speaker terminals on the back are of a higher quality than with the LA.

A clever line phase sensor confirms proper AC polarity. If your AC wall outlet is incorrectly wired with the live and neutral lines inverted, a yellow LED says so. This new connection is higher quality but it is still possible to upgrade further with Acrolink jumpers. Beyond these immediately visible differences, the internal design has more. The L A-II benefits from a more sophisticated power supply.

Most importantly, the L A-II couples its power transformer output by copper bus bar to the circuitry. Eliminating the usual connectors, power line impedance is linearized, the noise floor lowered and dynamic range increased. In the center is the power supply with a big EI transformer with discrete windings for the left and right preamp and output stages respectively while the protection circuits and VU meters run off their own power supply.

The output stage power supply sports four big Luxman-branded electrolytic filter capacitors and two big rectifying bridges with high-speed Schottky barrier diodes. On either side of this section are the output buffers whose PCBs screwed tightly to the heat sinks. Luxman also paid attention to the AC input with a high-purity brass IEC which non-magnetic nickel plating and a final gold skin for lower contact resistance.

Each mono amp runs two pairs of power transistors in class A push-pull to fulfil the modest power rating. The preamplifier section mounts on two vertical PCBs to the back plate.

This is controlled by a black Alps potentiometer mounted on the front panel which acts as mere reference encoder for the chips. The overall circuit is not balanced and the XLR input signal is immediately 'de-symmetrized'.

With this part, sound quality deterioration is claimed to be reduced to the minimum while channel separation and cross talk suppression were substantially improved over the previous L A and L A models. This scheme only returns distortion to the input, not the full signal and works " by isolating noise and distortion at the output from the music signal and sparingly applying negative feedback to suppress them.When you visit this website, cookies are placed on your device.

Perfectly traditional, the Luxman Corporation still relies on pure class A design and highest linearity to pursue this goal and their concept of perfection. If in the past this company from Yokohama seemed to have momentarily abandoned the high end, its strategy today is clearly focused on prestigious audio devices and high-quality standards.

To my mind, certain recently released Luxman components will remain references well into the future and as such, objects of desire for subsequent generations of vintage addicts. The new Luxman solid-state amplifiers seem built to last for decades and styled with a particular insensitivity to fashion trends just like Accuphase.

It might explain why elevated pricing finds real justification among aficionados and state-of-the-art listener as well as audiophiles looking for solid investments and products which offer sustainable value over the long term. After having introduced the LA inLuxman Corp. The results had been impressive. Clearly pure class A circuits still represent for Luxman the ultimate approach to amplification as it does for other prestigious manufacturers. Class A amplifiers are notoriously inefficient, dissipate excessive heat and require beefier power supplies than class AB amplifiers but are held to treat the audio signal with less distortion.

This benefits phase and circuit speed. Further stated benefits are superior transient response and drastically reduced transient intermodulation which many designers believe is caused by phase and time delays between input and feedback signals.The renovation was made to the buffer circuit input stage to allow smooth volume adjustment in 88 steps thereby minimizing the deterioration of sound quality.

Additionally, a 3D layout has been introduced in the new LECUA allowing the substrates to be placed in three dimensions. The attenuator circuit is connected directly to the amplification circuit to make the shortest signal routes and improve efficiency. The LECUA has exceptional durability and is capable of controlling the changes in sound quality that may occur due to external vibrations or sound volume adjustment.

Version 4. A high-inertia power supply circuit that combines a large capacity EI core type power transformer to which a vibration control feature has been newly added and a large capacitor block 10,uF x4 is an integral part of the LAXII.

This large capacity power supply circuit supports the sound dynamics of the unit by enhancing stability at the core of the design.

A discrete buffer circuit that is the equivalent to those used in the top end LUXMAN Cu separate amplifier is mounted on the output stage of the pre-amplifier circuit. This protects the purity of the audio signals whilst simultaneously enhancing the drive force for the power amplifier. The large capacity, low resistance speaker relays are connected in parallel in order to transmit the powerful drive force that is generated by the high inertia power supply circuit and the large scale output circuit without loss.

Connecting directly to the speaker terminals in this way significantly improves the damping factor from to The LAXII is designed using proprietary technology and customised parts to optimise the sound quality of this integrated amplifier.

For example, the round pattern board enabling smooth signal transmission, and a Beeline construction configuring the optimal parts locations and the shortest signal routes. In addition to this, the loopless chassis structure minimizes the ground impedance increase. The LAXII is designed introducing many custom-built parts and sophisticated technologies including newly developed high sound quality, low height block capacitors.

A loudness function interlocking with the sound volume is operable by the remote control. The tactile machined aluminium control knobs enable greater accuracy of selection.

TCL has a new batch of concept phones to show off in that use flexible-display technology in interesting ways. Two are foldables, including a unique "tri-fold" design with two different hinges allowing it to reach full tablet size when open.

New antennas are going up outside apartment windows, and most of us tend to keep our phones quite close to us at all times. It may not seem like phones have changed much since the first iPhone came out. But there are a few key trends in recent years that change the relationship between our phones and our hands.

OnePlus has an unusually confusing array of different "flagship" phones available right now, but the 7T is the newest mainstream model for most people. It's still quite high-end, but for a reasonable price and without some of the crazier features of the new Pro models, which most people don't need anyway.

In the phone world, there's no shortage of Black Friday deals in the US this year. CES is the world's consumer tech show.

This year, four products wowed us, each for a different reason. Samsung's second foldable phone takes a different approach: instead of folding larger, it folds smaller, much like Motorola's new razr foldable.

It's cheap for a foldable, but still quite pricey. Samsung's new flagship Galaxy S phones for are somewhat predictable in appearance and features, and they've leaked like crazy, but there are a few surprises.

There's no smaller, more affordable model like last year's S10e, nor is there a separate 5G model. All Rights Reserved.
