Twice Two: Bi-Amp 1-4

Is it possible to build an amp which is twice as good as the PHONOSOPHIE Bi-Amp 1-2? Well, it depends a little on your point of view and how you define it, but to us, the Bi-Amp 1-4 is definitely twice as good.

Not only did we managed to build four power amps in one slim case, but we also found that you can actually improve on the Bi-Amp 1-2, simply actively bi-amping your stereo speakers with four channels of fully enduring power - together with the optional active X-Over board from PHONOSOPHIE.

"When I consider what huge sums some people pay for a crutch and how much more the BI-AMP 1-4 would do, for the same or less, the choice seems obvious to me.“

This consequent Bi-Amp is dedicated to highest audiophile performance, unsurpassed in most pre & power amplifier combinations.

It plays music very accurately and deserves to be played loud. Where other amps begin to compress or run into heavy clipping, the Bi-Amp lets the instruments breathe. Even at extreme sound pressure levels, it keeps cool like a sportscar cruising at over 100 mph on a flat German Autobahn.


The compact Bi-Amp 1-4 incorporates a line pre-amp (phono if desired) and two independent stereo power amps providing four times 70 Watts. The transformer is real Toroid, not just toroidal principle, is extremely strong and low loss. In addition sound quality is improved by using star earthing and sophisticated voltage stabilisation.
Together with over-dimensioned conductor strips these are just a few of the construction features responsible for its amazingly dynamic and live-like sound.


Two in one
The speciality of this amp is two complete stereo amps in one housing. Thus enabling intelligent solutions for bi-amping and active systems. Bi amping offers better driving and control of the loudspeakers connected; they get more power.
Together with the high current delivery, the Bi-Amp 1-4 offers more precise audio imaging and stability, as if the musicians were standing in your listening room.


Job rotation: Exchangeable phono boards.
The phono boards are designed for quick exchange. You can switch a pc board for MM or MC cartridges optionally. Impedance and capacity settings are widely variable. They can be optimised for your favourite pickup when you order your PHONOSOPHIE amplfier.

Audiophile oriented circuit design with sophisticated board technology and selected components ensure, that the Bi-Amp is the right choice for the discerning ear.

Bi-Butt kicks your...
and gets you closer to the stage. The optional Bi-Butt board (erhem, stands for double Butterworth filter, or what did you think?) enables the adaptation of the speakers to the room. By limiting the bandwidth on both ends of the frequency range, the filter board is used in our integrated amplifiers, to improve the inherent dynamic behaviour of the amp and precision of the individual channels.


It's not over till X-Over.
A real speciality of this integrated amp is the optionally available active cross over network X-Over -2 (requires a four channel amplifier configuration). With that tiny little extra, you can activate and precisely adjust your passive speakers from brands like Naim, Linn, PHONOSOPHIE and others. This results in a dramatic rise in precision, imaging depth and low level information. It will sound even more real


It talks fluently German: DIN deals with connections
PHONOSOPHIE employs DIN sockets for all connections other than Phono, for which we use BNC terminals.

The lockable DIN connectors offer mechanical and electrical advantages. By using a common ground, we avoid the inclusion of different potentials, so that hum doesn't interfere with the sound quality.

BNC connectors are standard in the measuring business and everywhere where extremely low level signals have to be handled. No wonder that we believe that BNCs are the best choice for transmitting the sensitive phono signal to the amp.

Banana plugs offer the most precisely defined contact with the largest surface area of all loudspeaker connectors and guess what: that's why we use them in all our amps!


PHONOSOPHIE uses cases made of carefully treated aluminum (4 mm thick) with finest grade of surface polishing. In contrast to the heavy armour wrapped around common high end audio components, it will not suffer from vibration energy trapped between thick metal sheets.
Instead, this kind of lean construction offers more control when dealing with vibrations as they are eliminated from the cabinet in the shortest time possible. To reduce vibration effects even further, you can use our racksystem, which is complimentary to the cabinets design and supports them perfectly for optimum sound reproduction.

PHONOSOPHIE System remote. The system remote control is included so you can control everything – even third party components – from a comortable distance of up to 16 meters due to double LEDs..
