E.A.R. (ESOTERIC AUDIO RESEARCH) YOSHINO

Tim de Paravicini design - Hand Made in England

Production - All products are assembled at our production facility in Cambridgeshire, England which enables us to have full control over production quality. Production engineers are highly familiar with the products with the average experience exceeding 10 years with EAR Yoshino. Each product is built from start to finish by a single engineer, fabricating a personal touch to the product that is closer to reassembling craftsmanship than the anonymous mass produced objects we have all become too familiar with. EAR’s high-end products are built from the finest materials and supplies possible. We strive to source parts locally as it enables us to partner closely with suppliers and have tight control on quality, all while reducing our transportation impact.

Reliability - Valves or Vaccum tubes can be fickle things but with our extensive experience we believe we have a better understanding than most. When designed carefully they can produce a great deal of joy from their output whilst maintaining high reliability. Allowing users to leverage the great sound they produce without the drawbacks normally associated with valves. Being a mature developed technology, they are much more timeless that you would normally associate with electronics. We like to think they are more related to mechanical products like a finely crafted swiss watch.

Studio Influence / Recording each sound - Our belief is that recording sound is as important as its reproduction. Working closely with music production that includes the Exchange (London) and Mobile Fidelity (San Francisco), gives us a deep understanding of the sounds that are needed to be recreated. Reciprocity, with these studios, we aim to help extract the maximum possible from their setup that gives some of the luscious sounds you have probably already experienced from their work.

Acknowledging our work with music production, all of our equipment has been designed for the highest demands of this environment that include high-end audio quality but also robust reliability.

In Action - Some of musical talent that use our equipment include Pink Floyd, Ringo Starr, Kate Bush, Gary Barlow and Bob Ludwig.

EAR YOSHINO MC4 – MOVING COIL CARTRIDGE STEPUP TRANSFORMER

In an ideal world, every Moving Coil cartridge would work flawlessly with every phono stage. Unfortunately, many of the world's best Moving Coil cartridges have outputs too low for most phono stages to amplify properly. In order to 'step-up' these voltages to a level closer to what most MC phono stages would like to see, EAR has created the MC-4 Step-Up transformer. A low output MC audio signal enters one side and is output in one of four selectable voltages for greater compatibility with today's phono stages.Created by analog genius Tim DeParavicini, the MC-4 is designed by an audiophile for audiophiles. Built with the same attention to detail that made the EAR 834P phono stage world famous, the MC-4 has superb sound quality, is built like a tank and is flexible enough to accommodate even the most demanding cartridge load. The key to the MC-4's flexibility are the 4 input taps on the rear. The MC-4 has four separate stereo inputs, all of which feed a single stereo output. This allows the user to configure the output of the MC-4 to offer the optimum voltage. Each input provides a different impedance, 3O, 6O, 12O, or 40O. These produce output of 30x, 24x, 18x or 10x input voltage, respectively.

Therefore, a 0.2mV cartridge would produce the following output voltage depending on the tap chosen:

- 3O=6.0mV
- 6O=4.8mV
- 12O=3.6mV
- 40O=2.0mV
