Audeze LCD-2 - The Original Planar Headphone That Put Audeze On The Map
Recommended By Scan Pro Audio
The LCD-2 is Audeze's original "game-changing" headphone and the one that propelled them into a world of rave reviews.
The LCD-2 is the most forgiving of the LCD Collection due to a magnetic structure that provides extremely low distortion. Fast and dynamic with terrific bass, the midrange - where music lives - is superb as are the golden highs. Audeze's proprietary technology eliminates breakup modes found in other designs and improves clarity.
The ear cups of the LCD-2 are made from environmentally sustainable Bamboo Composite. The sloped ear pads are dual purpose and are designed for aesthetics and functionality. These have soft lambskin leather and the ear pads have been handcrafted to look great and offer the right amount of firmness for a comfortable fit that provides the proper amount of isolation and seal. Additionally, the sloped design provides a more stable fit while positioning the driver more directly towards your ear to ensure correct imaging and sound signature.
These headphones benefit greatly from a dedicated headphone amp, we recommend the Audeze Deckard, Chord Hugo or Mojo combined DAC & Amps, or the Nuforce HA200 & SPL Phonitor Mini Analogue amplifiers for the LCD-2's
Exclusive LCD-2 Planar Magnetic Technology
Deep Bass. Liquid Midrange. Sweet Treble
Audeze had one goal in mind when designing the LCD range of headphones "To recreate sound precisely as the artist intended". The LCD range produce incredibly accurate and detailed sound, which has won Audeze many awards in the Hi-Fi world and gained many professional studio users including Ken Andrews (Paramore, Nine Inch Nails), Rob Swire (Pendulum / Knife Party), Richie Hawtin, Andy C & Noisia, as well as many of the world's leading mastering engineers.
• Audeze Headphones utilise Planar Magnetic technology which overcome many of the limitations of cone-based drivers.
• Unlike conventional cones which are attached to a voice coil with a single magnet, Planar Magnetic drivers have two sets of magnets, with the diaphragm etched onto a wafer-thin film in between them with one set of magnets pushing as one set pulls. As the magnetic field is distributed across the entire diaphragm, it can move faster, reproducing the waves much more accurately and also reduces distortion. Other headphones and speakers often have square waves that look more like sawtooths, due to the cone not being able to move as fast as required.
• Planar magnetic drivers are also a lot more durable than dynamic drivers as only the diaphragm actually moves in the headphones, so the drivers wont degrade as they get older.
• Audeze made many changes to the basic planar magnetic design, with them being renowned for their extended low frequency response and exceptionally sharp transients.
Designed, Engineered and Handcrafted In Audeze's California Factory
The LCD-2 is thoroughly engineered for long-term comfort and beautiful sound. We closely match our planar transducers, and match our beautiful factory-made wood rings by grain and colour.
Industrial Design By Audeze
Exotic Woods. No Danger
We use Shedua wood from tropical west Africa It's not on the watchlist and is reported by the IUCN as being a species of least concern. We also match the earpads by leather texture and colour. You can choose lambskin leather or Microsuede headbands and earcups that are filled with foam carefully selected for best sound and contribute to the level of comfort during long listening sessions. Pair the LCD-2 with a quality headphone amplifier or integrated amp for best sound.
These include the new "Fazor" waveguides in each earphone assembly. The Fazor elements improve clarity, focus and the already spectacular holographic imaging. The two Fazor elements are placed just outside the two magnet structures that surround the diaphragm in each capsule. They guide and manage the flow of sound around the magnets.
NuForce HA200 Class A Headphone Amplifier
SCAN PRO AUDIO RECOMMENDED: This is a pure class A amp, the sound quality is studio reference class, this is truely a fantastic analogue amplifier, perfect for anyone who already has top-grade converters.
The HA200 is a high performance headphone amplifier engineered to satisfy the requirements of the most devout headphone enthusiast. Capable of driving any set of headphones with more detail and greater scale, you will find the remarkable transparency reveals previously unheard nuances in familiar material. For the technically discerning, the HA200 utilises a purist Class-A design in a constant current configuration and offers true single ended output performance. For even greater fidelity two units can easily be configured for simultaneous use providing true balanced mode with increased transient speed and dynamic control.
The Class-A topology is widely recognized as being the purest form of amplification, and this is because other topologies such as Class B and Class-AB require that two output devices be operated in "push-pull" fashion in order for each to handle one half of the musical waveform. At the point where a given device "hands off" to its opposing counterpart, it must "turn off" or stop conducting current until the waveform polarity ultimately returns to that which the device was assigned to handle. Then and only then will that device begin to conduct current again, while in turn, the opposing device must now stop conducting. This "sharing of polarity" behaviour leads to what is commonly termed "crossover" or "notch" distortion.
Due to the battery-like type of charge storage within them and their inherent speed limitations, the transition between opposing output devices can never be perfectly aligned in time to produce a seamless flow of electrical current. Typically, a small discontinuity or "notch" at the zero-crossing (crossover) point can always be observed by an oscilloscope connected to the output terminals of the amplifier. This notch represents distortion and is of a static nature, meaning its amplitude remains the same at all signal levels. Therefore, this distortion represents an ever-increasing percentage of the total output as power levels are reduced, and contributes to a "grainy" sound that is particularly audible and quite irritating at low listening levels.
Conversely, in Class-A operation the output device is never completely shut off, so there is no "turn on" or "turn off"" time requirement, per se. Hence, there are no issues with charge storage or any ensuing crossover distortion. Class-A designs generally offer better high frequency performance and over-all feedback loop stability. This second point is especially important because all amplifiers produce some distortion, but compared to other topologies Class-A's superior feedback loop stability means that fewer high-order distortion harmonics are generated. The result is a more natural and harmonically accurate reproduction that is significantly less fatiguing.
Single-Ended (SE) Design
One unique advantage of Class-A design is the ability to employ only a single output device, with the technique commonly referred to as single-ended design. Quite simply, such a configuration guarantees that there is no opportunity for the generation of crossover distortion, and therefore is considered by many to be the purist form of amplification possible. The HA200 operates in full SE Mode when used in its stock stereo configuration.
Furthermore, the single output transistor is operated with a rock-solid constant-current bias, which provides for very stable control over the output signal at all times. Musical waveform accuracy is maintained such that typical "overshoot" and "ringing" artefacts are virtually eliminated. The sonic effect is one of a fast and authoritative response manifesting as exceptionally accurate and natural transient reproduction at all frequencies and dynamic levels.
Balanced Headphone Mode
Unique to the HA200 is its ability to quadruple output power by simply adding a second unit and operating them together in "Balanced Mode." For this configuration, all that's needed is to use the XLR inputs and outputs on each HA-200 along with a special cable adaptor for connecting the headphones.
In Balanced Mode, four completely separate amps (2 per unit) are utilized to drive the four phases of the music signal (right normal, right inverted, left normal, left inverted). Please keep in mind though that this is NOT the same technique as mentioned above in the "push-pull" Class-B scenario. In Balanced Mode, all transistors are biased in Class-A so as to conduct current at all times - only the phase is inverted 180 degrees in the case of the left & right inverting amplifiers.
The primary benefit of such a design is that the available output voltage is doubled, so the actual output power is quadrupled. It also doubles the effective slew rate (the maximum change in voltage per second that an amplifier can achieve), as both amplifiers are operating in opposite phase to increase the dynamic realism of the music. While "technically" not a pure SE design, since Balanced Mode remains in full Class-A operation at all times it can be thought of as a "dual SE" architecture that retains the best of SE performance with the added benefits of higher power and better dynamic control.
Sonically, the resulting sound is completely "grain-free," the soundstage is wide and deep while instruments and voices are reproduced with extreme clarity and purity of tone. The incredible power and dynamic control over the music simply must be experienced to be appreciated.
A Small Price to Pay
The one slight disadvantage that Class-A amplifiers have is that transistor bias current must be set such that the output transistor continually operates in the centre of its "linear region," which simply speaking is the midpoint between its fully-on and fully-off limits. Therefore, regardless of the actual audio power being used Class-A amplifiers continuously consume their full-rated output power and dissipate that power in the form of waste heat.
