“The phonostage”

best sounding, most neutral

Jumper vs. Dip Switches:
A sonic Advantage

No hiss, no noise

The new EINSTEIN “The Phonostage” is a superb phono amplifier with a discrete 10 single transistor design for the input stage, combined with highest quality op amps in the two other amplifier stages. Such an incredible effort is rare in the audio industry, but the superb technical specifications justify this commitment. Due to the perfect shielding and the sophisticated circuit design, this phono amp is dead quiet. No hiss, no noise which can damage the fragile signal the cartridge delivers.

“From the softest note
to the boldest chord”

The inner values

Whisper-Quiet Audio Amplification

As a typical EINSTEIN design “The Phonostage” is a double mono design guaranteeing perfect channel separation. The EINSTEIN principle of the floating ground avoids hum loops. The power supply is huge with enormous headroom and can easily provide more than enough power for the actual phonostage. “The Phonostage” is specified for Moving Coil Cartridges only. The perfect impedance load can be adjusted by custom made RCA plugs in the rear panel of “The Phonostage”. Thus there are no sound limiting interferences of dip switches in the signal path for cartridge loading.

Unlocking Vinyl's Hidden Details

The gain can be set up to 68dB or 74 dB to achieve the best technical and sonic results for low level cartridges and higher output level cartridges. This is done by a simple jumper to avoid limited sound performance caused by noisy Dip switches in the signal path. The sound is absolutely stable and in focus. A perfect three dimensional soundstage with details you have never heard from your vinyl records. Even the finest details will be transferred to your ears. The dynamics over the complete frequency band are something very special – this phonoamp makes pure, delicate, smooth, explosive and exciting music.
