Description
It is well known that the electrical characteristics of turntable cartridges differ greatly from one cartridge to another. Ohm’s law shows that Moving Magnet cartridges will generate larger voltages while Moving Coil cartridges are generally more efficient at delivering current. Phono stages should take full advantage of the cartridges’ strengths and amplify the signal in the way they work best.
With two dedicated MC current inputs and one MM/MC voltage input, the P1 provides the optimal coupling to all types of cartridges.
In addition, discrete class A stages as well as the highest grade, tight tolerance components allow the P1 to deliver high performances for a transparent yet natural sound.
Options:
2-channel phono preamplifier including TWO complete chassis (each with 1x PHONO_PRE), for a TRUE MONO system, per pair: CHF 47'600.-
Additional EQ curve boards: CHF 1700.- the pair Picture
This pair of option boards allows optimal playback of EMI, Columbia, Decca and Teldec records pressed prior to the RIAA standardization.
External Power Supply:
X1 external power supply: CHF 15'100.- Picture
Improves the overall P1 performances by adding an external power supply unit.
Same unit dimensions as the P1
