DIAMOND Line

The Demidoff Diamond is a state of the art, two massive chassis solid state stereo integrated Amplifier providing high current combined with super high efficiency.

It uses single ended Multi-Powered transformers, handcrafted to ensure the highest quality controls in every stage of the building manufacturing.

The Demidoff Diamond uses the very finest implementation of the Mirror-Amp™ pre-amp. This deploys a gain stage made with a proprietary cascade differential amplifier with a mirror current, providing a super-linear signal virtually eliminating distortion. The output section implements one further improvement to the Demidoff series. It is been modified to have the highest dynamic power, linearity and efficiency resulting in an unbelievably smooth sound performance.

The power supply put in a different massive chassis is managed by 18 different massive transformers made specifically on strict specification. Eight custom Golden transformers wired with silver alloy work as “pure” power energy suppliers. Other eight Transformers, mechanically isolated, are used as power decoupler filtering the DC power enters the preamplifier Mirror-Amp™ stage. Such separate massive inductive power supply guarantees the lowest interferences from AC power. All the strategic power & audio sections are wired with Rounded Solid Silver bars. The RSS is a 2mm diameter bar made with 92.5% pure silver and 7.5% electrolytic OFC. It provides the very best conductivity available.

The input wires are connected to the customised selector with a 2.5mm silver cable specifically made for this ultimate Amplifier. The dedicated audio section of the Demidoff Diamond is positioned in a separate chassis specifically made for the audio signal only. The audio output stage is made with two RSS rails built around the proprietary active cryogenic

refrigerator, the CRB™. The CRB™ let the amplifier work at a very low temperature producing the highest conductibility

available acting as a virtual “super conductor”. As per all the Demidoff amplifiers, the Diamond does not have active nor passive filters on the audio signal. We have designed specific passive thermal switches to switch the amplifier power off completely if it reaches a critical power transistor temperature.

Its chassis is completely made of aluminium and stainless steel to minimize RFI and EMI interference through having a completely non-magnetic environment! The Demidoff Diamond has two high precision Blue Fluorescent Vu-Meters and a remote control for the volume, both powered by a dedicated transformer to avoid any kind of interferences on the signal path that could affect the sound quality. The Demidoff Diamond supports a wide range of inductive and resistance loads so it can be matched with any kind of audio cable, allowing users to employ their favourite wiring combination. The use of customised components matched with such innovative separate power stage ensure superior high level sonic performance.

The Demidoff Diamond is equipped with all custom design connectors. It features high quality solid silver speaker  connectors insulated through Teflon® washers and Bolts.

This Decade Edition Demidoff Diamond amplifier uses only the finest electronic components and represents the absolute STATE OF THE ART for 21st Century electronics design.
