Bit & Beat BLUEAMP Op.6, No.1 "Gradevole"
























































































Driving circuit onsists of the most general and simple two-stage differential amplifier to match the output terminal, and uses a solid capacitor with excellent performance for significant voltage gain and feedback circuitry to maintain maximum linear characteristics even at low levels.

The current amplification terminal uses Mosfet with a small driving current and the bias circuit is designed with a stable bias by configuring an auto tracking circuit to cope with changes in temperature and conditions so as to be free from environmental influences.

The digital part prepared for the convenience of PC-Fi user is housed in a separate chamber so that it is not contaminated from jitter, and all connected signal lines are filtered and only sufficiently purified signal was processed to be connected to the amplifier.

A sufficient capacity transformer and a maximum speed regulation are configured and The power supply capacitors supplied to the amplifiers have been carefully selected to ensure sound quality and stability by adopting the proven audio capacitor.

Wing Acoustics Zerø Passive Shelf Speakers






































































An entirely new way to generate sound, Wing Zerø shelf speakers deliver breathtaking treble performance, mid-range never before experienced and market-leading bass for a compact 2-way shelf speaker that, remarkably, stands only 230mm high.

Wing Zerø shelf speakers feature the world’s first acousticWING®, a revolutionary mid-treble driver that, as a market-leading feature of this technology, delivers zero energy storage over exceptional bandwidths and lightning fast transients.

Fuse this acoustic tour de force with a 3” dedicated subwoofer, passive radiator, and obsessive optimisation around a compact aluminium enclosure and the result is purity and clarity beyond that of loudspeakers priced in the tens and hundreds of thousands of dollars.


Impossible

The acousticWING® diaphragm is designed like no other. The Waterfall Plot below is a measurement of the acousticWING® that sits at the heart of Wing’s Zerø passive shelf speakers. It unequivocally shows Zerø resonance-distortion over the widest operating bandwidths. The result is unparalleled sound purity, breathtaking mid-range and treble performance you never knew existed. Audio Engineers have stated this would be impossible to achieve using conventional dynamic drivers.
















Market-leading bass extension

The Wing Zero achieves an unprecedented low crossover frequency of below 500Hz which is only possible through the extraordinarily wide bandwidth of the acousticWING® driver delivering unparalleled mid-range and treble performance. Such a low crossover relieves the subwoofer of any sub-par mid-range responsibilities, concentrating it’s performance on delivering market-leading bass extension (-6dB @ 30Hz), that belies the speaker’s exceptionally small form factor.


Beautiful heavy metal

Weighing in at a rock solid 7kg, the incredibly compact Wing Zerø shelf speakers stand only 230mm tall. 7mm thick, formed aluminum outer walls are finished in premium anodising for an exceptional beauty and durabilty.


Acoustic lobing extinguished

Lobing refers to possible interference of sound waves radiating from multiple sources, leading to a potentially irregular off-axis response that can colour audio reproduction. In many two-way speakers, at certain listening positions certain frequencies can be almost completely cancelled in the crossover region. It is at the crossover frequency that the effects of lobing are of greatest concern. The incredibly low crossover achieved in the Wing Zerø shelf speakers virtually eliminates acoustic lobing, preserving in pristine state, the tonality of original audio across a wide range of listening positions.


Ironless

The acousticWING® is an ironless loudspeaker driver. Consisting of a radically simplified motor design featuring a single moving magnet, stationary heat-sinked coil and ZERO iron pole pieces, the acousticWING® eliminates non-linearity associated with pole piece hysteresis– a significant cause of distortion in conventional loudspeakers.

Luxman CL-1000













































































$20000

Luxman’s new flagship control amplifier, the CL-1000 is the spiritual heir to the legendary C-1000, launched in 1975. Yet even as it salutes the past, the new preamp looks forward with an all-new LECUTA volume control system, a nanocrystal core transformer, Luxman’s proprietary oil-impregnated capacitors and more.


The heart of any preamplifier is the volume control. If not executed properly, it can cause left/right channel imbalances and introduce subtle but tangible distortions at low volume. For this reason, Luxman created the highly regarded LECUA attenuator system. The CL-1000 refines that concept with LECUTA, the Luxman Electronically Controlled Ultimate Transformer Attenuator.

The Volume knob is a 34-step rotary switch that triggers 34 relays, located completely outside the signal path. In turn, the relays activate 34 taps on matching left and right transformers. These transformer taps set the volume in carefully calibrated steps. Because transformer cores can influence sound quality, Luxman engineers selected FineMet® core material from Hitachi Metals, Ltd. This has a unique nanocrystal structure for high saturation flux density, high relative permeability and low core loss. As a result, the CL-1000 delivers uncompromising sound, even at low volume.


Circuit Design

While some are rediscovering the magic of vacuum tubes, Luxman has been making tube audio components without interruption since the company’s earliest days. The CL-1000 embodies this expertise, complete with refinements to take vacuum tube audio a major step forward.

Super Permalloy input transformer. Because transformers can have a profound impact on vacuum tube audio quality. Luxman chose an input transformer with a high-permeability Super Permalloy core.

Six JJ Electronic E88CC dual triodes. The CL-1000 uses two-stage PK NF amplification, with both the attenuator driver and the output stage built with vacuum tubes from JJ Electronic. Luxman selected E88CC dual triodes for superb reliability, low noise, attractive dynamics and a densely detailed midrange.

Custom capacitors. Luxman couples the two stages with the company’s own, oil-impregnated capacitors. Originally developed for the MQ-300 amplifier, these help deliver satisfying music reproduction with superb current handling.

Left/right Super Permalloy output transformers. The output stage features the sonic benefits of Super Permalloy cores in independent left and right transformers.

Articulator function. Luxman’s deep experience with signal path transformers has revealed one downside: residual magnetic fields in the cores. For this reason, the CL-1000 oscillates and demagnetizes the transformer cores every time the owner turns on the power. For an even higher degree of sonic purity, users can perform manual demagnetization with the Articulator switch.

Versatile MM/MC phono preamp. The CL-1000 accommodates both Moving Magnet and Moving Coil cartridges with an audiophile-grade phono preamplifier. Six-position switches on the rear panel enable users to optimize impedance and capacitance.

Robust, stable power supply. To deliver the most demanding musical peaks without effort or strain, the CL-1000 power supply features large, independent left and right transformers and high-grade filter capacitors.


Robust Chassis

External vibration is the enemy of vacuum tube audio reproduction. Under the surface, the CL-1000 chassis takes advantage of a comprehensive engineering program to fight even subtle distortions caused by air-borne or shelf-borne vibration.

Triple-layer aluminum front panel. Reminiscent of Luxman’s classic C-1000, the front panel uses precision machining to unite three thick layers into one massive, anti-resonant assembly.
Natural walnut cabinet with rosewood gloss finish. Additional protection from resonance comes from the elegant cabinet, which is covered in walnut.

Cast iron isolator feet. Massive iron feet feature a density gradient to block and diffuse shelf-borne vibration.

Rigid box chassis. The chassis itself forms an anti-resonant container with internal partitions helping to reduce vibration further.

Internal rubber dampers. For added protection, Luxman isolated the circuit boards from the main chassis with special rubber dampers.

Alloy input and output terminals. The RCA input and output jacks consist of an alloy that combines the conductivity of copper with the durability of brass.

Gold-plated AC input. The AC input contacts are treated with non-magnetic nickel and plated with gold.
