Phasemation EA-550 Monoaural Phono Amplifier

A separate type phono amplifier (2 units), all discreet, all-stage symmetric non-feedback circuit that draws out the music’s reality and the artist’s passion.
Adopted a strong chassis structure of a 2 unit box with Lch and Rch being independent and completely monaural. Following the elegant design of CA-1000 / T-2000, a strong housing structure consisting of a 10mm thick aluminum slant front panel, a 1.6mm thick copper plated steel chassis base and a 1.6mm thick copper plated steel sheet cover was adopted and this ensures rigidity and reduces magnetic deformation.

A heavy weight metal insulator that blocks external vibrations is used for the feet.

In addition, the played sound supported by the left and right divided equalizer part and the powerful power supply part has high S/N and high resolution.
The played sound can be enjoyed with overwhelming realism and with a panoramic stage.

V-I / I-V conversion type all-stage symmetrical non-feedback amplifying circuit due to all discreet parts.

The negative feedback amplifier which is the mainstream of modern amplifiers constantly compares the input and output signals for both the semiconductor and vacuum tube and this difference (amended signals) can be amplified with high precision at low cost because it is amplified as an input signal. However, there is a time delay between the input and output signals which cannot be solved theoretically and this generates a TIM distortion and the like and this is a big reason why sound satisfaction cannot be attained from negative feedback amplifiers.
At Phasemation, amplifiers of semiconductors and vacuum tubes are all composed of non-feedback amplifiers. For non-feedback amplifiers, there are no amending operations like the negative feedback amplifiers and therefore high precision/technology of structured parts and circuits are required.
As a result, it is played with no information remains on the sound source (record) and in terms of sound quality, it can play the music with excellent inspiration, dynamics, and shadowed (or the like) expressions.
