Our philosophy

echo-diastasis: An invitation-challenge to your hearing

Innovations in the field of high-end audio were always those things that marked the evolution and fuelled the continuation of research in high fidelity. Innovative ideas throughout this evolution in most - if not all - cases were the result of both scientific knowledge and inspiration, and mainly acoustic documentation and proof.

With that in mind in Echo-Diastasis we design and produce our products, which we believe include all the elements that make up a handmade musical instrument. So they are assembled entirely by hand, with continuous and individual control of all parts to the last production step. The choice of materials is made with the highest standards and everything is thoroughly tested before the product reaches the consumer. All our products carry special design E-core transformers, to achieve the maximum possible RF noise rejection ,from the mains power feed.

Integrated amplifier - I-79

I-79 combines and integrates the design innovations of the A-79 and PRE-79, to a more economic proposition with less power, without lacking in sound quality of the individual units. The I-79 completely avoids the use of a potentiometer in the signal path, while maintaining the simplicity of its design achieving, speed, transparency and musicality.

Phono amplifier - PH-79

Designing a phono preamplifier has always been one of the most difficult tasks in the audio devices design era, because it tries simultaneously to solve a number of emerging design problems, where improvement in one area usually is not working beneficial for others. Inside PH-79 there are special enhancement devices, an additional noise rejection stabiliser and a special topology, ensuring that the delicate and low voltage signal of every phono cartridge (moving coil, magnet or iron) in the path to any amplifier, will be free from unwanted and annoying noises. With active equalisation, zero feedback, separation of high and low frequency poles and matching materials, the serious designing issue of the RIAA equalisation is getting resolved with absolute precision.

Pre amplifier - PRE-79

PRE-79 was designed to function completely different from the usual preamplifiers. With a whole new volume control module attached, there is no need of a potentiometer (or attenuator) in the signal path. This application is a major step towards the non-alteration and degradation of the original signal, which additionally is achieved without using a negative feedback.

Power amplifier - A-79

Although the A-79 is a transistor amplifier, its circuit design is treated as a tube amplifier remaining incredibly simple, leaving the entire design to focus on materials quality and continuous accurate measurements, reaching the desired acoustic result. Furthermore this final result, is derived from intensively acoustic sessions.
