What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Marantz PM 6006

EISA AWARD Best Product 2016-2017
European Stereo System: 
Marantz PM6006 (and CD6006)
 The PM6006 is an upgraded successor of the multi-award-winning PM6005. We've retained the pre-amp and power-amp sections that exclusively feature discrete components - not a single IC in sight of the signal path. The PM6006 is upgraded for peak current at the amplifier stage, which makes it possible to refine the sound for you in much more detail.
You can connect this superb integrated amplifier directly to a vast range of digital sources and use its superior 24bit/192kHz high current CS4398 DAC to create an unbelievably high level of audio enjoyment with new media. The unit now includes 2 optical and 1 coaxial digital inputs (an additional optical input from the predecessor, PM6005), and the complete digital section is fully shielded by an extra metal housing to ensure that the digital stage has no effect on the analog signal.
All of the original features—such as five-line audio input including phono, two-pairs of gold-plated speaker connections with the convenience of bi-wiring, and a remote handset—are all still there. The lower impedance shielded Toroidal transformer, as well as customized components and unique Marantz HDAM modules care for powerful, dynamic and detailed original Marantz sound. In short, the new PM6006 is a new star with excellent genes.

Marantz CD 6006

EISA AWARD Best Product 2016-2017
European Stereo System
MARANTZ CD6006 (and PM6006)

 The CD6006 is a fine-tuned version with even more specially selected components and new layout circuit compared to its CD6005 predecessor. We also added more rigid feet to further eliminate vibration. The oversized power supply feeds the digital and analog circuitry of the player, where the high-quality CS4398 DAC converts digital signals to analog, this is then 'pushed' to the gold-plated synch outputs by Marantz's own small signal amplifier, the HDAM-SA2.
The CD6006 is a match made in heaven for the music lover who wants nothing but the best performance at an attractive price, and it is also perfect for lovers of portable music, thanks to its iPod-digital connectivity. The CD6006 also features a newly developed, complex headphone amplifier with Headphone amp gain setting for a wider range of headphones. In addition, we have included a new remote that also controls the PM6006 amp.

Bowers & Wilkins 802 D3

EISA AWARD Best Product 2016-2017
European High-End Loudspeaker:  
  If you’re looking for stunning realism without the studio-sized footprint, the 802 D3 is the answer. It’s slim proportions make it a comfortable fit for both domestic spaces and recording environments. At home or in the studio, it will reveal depth and detail in music you never knew existed.
The 802 D3 delivers pristine, high-performance sound in any environment. Its Diamond tweeter partners with a Continuum cone to ensure revealing natural sound that will leave you speechless.
Continuum cone
The Continuum cone delivers pristine midrange performance by effectively negating the break-up behaviour that can adversely effect this all-important part of the spectrum.
The innovative plinth provides an incredibly solid base for the 800 Series Diamond. The spikes are ideally positioned below the cabinet, and ingenious engineering allows you to switch between castors and spikes with ease.
Solid body tweeter
The Diamond dome tweeter is housed in a solid piece of aluminium. This mechanically inert structure provides an incredibly rigid platform from which the tweeter can deliver crystal clear sound.
Bracing is essential in keeping a speaker stable, so the character of instruments comes through cleanly. Developed using computer modelling and constructed from wood ply with metal reinforcement, Matrix offers the ultimate in bracing.

Elac Debut F6

EISA AWARD Best Product 2016-2017
European Loudspeaker
 The Debut F6 loudspeaker combines the advanced drivers of the B6 bookshelf in a floorstanding 3-way, bass-reflex design that takes Debut performance to the limit. With sound that rivals speakers costing many times more, the F6 shows that quality components and superior engineering are a winning combination every time. Combine a pair of F6 with a Debut powered subwoofer for a truly stunning two-channel audio system.
Custom-Designed Drivers with Aramid-Fiber Cones
Aramid fiber is employed in the woofers of all ELAC Debut passive speaker systems. Aramid fiber offers a superior strength-to-weight ratio and improved damping characteristics over conventional paper or plastic drivers. This added strength means arriving at designs that achieve a broader bandwidth with smoother response.
Silk-Dome Tweeter with Deep-Spheroid Custom Waveguide
The waveguide surrounding the new ELAC high-frequency driver features a custom, deep spheroid profile to improve directivity control and shield the dome tweeter from cabinet diffraction modes inherent in traditional box enclosures.
Intricate Cossover
A custom multi-element crossover with high-grade components in each speaker ensures smooth transition between the drivers.
Robust Cabinets
Every ELAC enclosure is engineered for the long run with thick MDF outer walls and a luxurious textured vinyl finish. The cabinet of the F6 incorporates specially designed internal bracing to add stiffness and strength to the cabinet’s outer walls. This bracing greatly reduces cabinet vibration, which causes unwanted coloration to the sound. ELAC believes that the only parts of a speaker that should be moving are the speaker drivers themselves.
Superior Build Quality
Count the parts and look at them closely. These don’t look like the components that go in such competitively priced speakers, but rather, speakers that cost much more.
