FROM MONO TO LIFELIKE STEREO

Authenticity Amplified

The Powerampshowcases the culmination of relentless innovation, combining advanced single ended circuitry with meticulous attention to detail. Its exceptional performance is characterized by unparalleled clarity, natural dynamics, and an absence of distortion, allowing you to rediscover your music library with a heightened sense of authenticity. With “The Poweramp”, the boundaries between artist and listener dissolve, offering a pure and unadulterated audio experience.

“EMBRACING STEREO’S DIVERSITY”

COMMITMENT TO SONIC FIDELITY

The development of our latest stereo amplifier, “The Poweramp”, drew significant inspiration from the groundbreaking design of our mono amplifier, “The Silver Bullet OTL”. The primary objective was to uphold our commitment to delivering lifelike music reproduction, a goal strongly influenced by the exceptional listening experience provided by “The Silver Bullet OTL”.

The inner values

SINGLE ENDED CIRCLETRON

This seemingly simple goal – whilst also keeping an applicable price structure in order – was quite literally driving us in circles. After years of trial and error, the conclusion was to copy our own “The Silver Bullet OTL” circuit , but with transistors in the output stage. Yet again this resulted in an EINSTEIN typical circuit which, outside of our own adoption, hasn’t seen much of an audience in the world of high-end audio. As in our OTL designs, the circuit is designed as fully balanced and thus is able to captivate with an incredible signal to noise ratio and the elimination of typical sound influencing circuit distortions.

We have named the power amplifier circuitry Pure Class A / Balanced Double Single Ended Circeltron Architecture. This circuitry is identical to the one used in “The Amp Ultimate“.

Through a high bias current design, we attain remarkable linearity and an extended bandwidth across the frequency spectrum, ensuring uncompressed dynamics and revealing even the subtlest details at any listening level.

LINEARITY PERFECTED: EI PCC88 IN THE POWERAMP’S INPUT STAGE

In line with our OTL circuitry, the new “The Poweramp” incorporates a cascade circuit featuring a differential amplifier. The input stage of “The Poweramp” employs double triodes, specifically the EI PCC88, renowned for their exceptional linearity. Similar to the OTL, this circuit utilizes the incoming signal to generate a perfectly symmetrical and balanced signal, amplifying it to the desired level. This ingenious design allows us to employ two identical power amplifier transistors in the output stage, possessing technical specifications comparable to the power tubes found in our esteemed “The Silver Bullet OTL”. The floating mass configuration further ensures freedom from interference issues, such as ground loops, that can otherwise degrade the signal-to-noise ratio. As is customary with all EINSTEIN electronics, the volume relay remains outside the signal path, upholding our commitment to pristine audio reproduction.

STABILITY IN ANY CONDITION

Like all other EINSTEIN circuits, the utmost sophistication in power supply is imperative to uphold the stability of our groundbreaking circuits. The incorporation of substantial energy reserves, meticulous decoupling, and steadfast stabilization of critical supply voltages guarantees unwavering performance even in unfavorable power conditions. With an exceptional damping factor and remarkable power supply stability, “The Poweramp” effortlessly drives a wide range of speakers, even during demanding peak-to-peak impulses. Naturally, high-quality speakers reap significant benefits from the prowess of our latest amplifier.

A CONCERT EXPERIENCE AT HOME

With the introduction of “The Poweramp”, we have not only achieved our objective but surpassed it: a truly lifelike audio experience characterized by unrivaled clarity, natural dynamics, and an absence of compression. Immerse yourself in your music like never before, as if you were front row at a live concert, captivated by every nuance and emotion.
