In addition to the elements that characterized its predecessor, namely:

• special amplification devs,
• additional noise rejection stabilizer,
• special topology that ensures that the delicate and low voltage signal of any head (movable coil, magnet or iron) in its path to any amplifier will be free from unwanted and annoying noises.
• active equalization,
• zero feedback,
• absolute precision in RIAA equalization that is innovatively achieved by separating high and low frequency poles and by matching materials.
• specially designed EI core transformers to achieve maximum possible RF noise rejection from the supply line.

The following have been added to the new Echo Diastasis PH-79 V.2 phonographic head preamplifier:

• better, reinforced and rigid chassis,
• new redesigned front panel with easier-to-adjust switches,

Pre-79 v.2 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.
