The Absolare Preamplifier has been designed with the goal of creating a pure and emotionally engaging preamplifier.

A preamplifier capable of conveying the deepest musical integrity within the faithful reproduction of the recorded performance.

Through several years of methodical research, the Absolare team has indeed come to believe that there is an absolute in terms of identifying the right components and correctly implementing them within the ultimate minimalist pre-amplifier design. A synergized ensemble of customized, cost-no-object and rare components all critically chosen for their superior performance. The design principle in the Absolare preamplifier is best reflected in the following three words – “Purity, Control, and Power”. Purity of Signal, control of resonance and clean power.triodePreamplifier3

The Absolare Preamplifier is housed in a single chassis with separate power supply and signal sections internally partitioned by a thick aluminium wall. This design eliminates unwanted magnetic influence of AC noise on the signal path. The laser cut, precision welded 3mm aluminium chassis is enclosed in leather clad high-density fibre panels to minimize mechanical resonances. On top of these, a separate large CNC carved aluminium housing provides a vibration free environment for the tubes and signal components. Supporting the entire structure is a 5mm thick aluminium base plate that also provides a stable foundation for the feet. All signal connectors are gold/silver plated tellurium copper. All tube sockets are pure teflon with gold plated copper contacts.

Electrical filtering is implemented in three stages: a pi-type capacitor-resistor filter; an active regulator and another large pi-type filter. All filters employ the highest grade Mundorf capacitors with ultra-low ESR to preserve maximum levels of dynamics and detail in the signal. All internal power cabling utilizes Echole proprietary alloys. Schottky diodes provide fast and noise free rectification while a significantly oversized Lundahl transformer mounted on a slab of palisander wood supplies all the current demands instantly. Heaters are DC regulated and filtered with Mundorf capacitors. triodePreamplifier4
The all tube signal section is configured in pure Single Ended Triode architecture. Output impedance is kept low by a mu-follower design with a minimum number of components to preserve sonic purity. Signal components are directly mounted to the underside of a large CNC carved block of aluminium with point-to-point soldering. Input connectors are mounted immediately behind the signal stage, keeping all Echole signal connection cabling to the minimum possible length. Both input selector and attenuator are also mounted within the signal housing, next to signal section. Balanced models employ input and output transformers for balanced operation.
