Benz Micro Lukaschek PP-1 Phono Stage Preamplifier for moving coil cartridges. The small size of the PP-1 allows close placement to the turntable, minimizing signal leads from the tonearm. The whole power supply is inboard the PP-1 chassis except for an external power transformer, which is outboard to eliminate magnetic field interaction. The miniature size of the PP-1 also allows all circuit components to be very close to one another. This significantly reduces circuit board traces, which could introduce noise and sonic degradation. The PP-1 is optimized for moving coil amplification, thus does not provide switches and or jumpers for gain setting or resistive loading. This elimination of unneeded circuit junction points preserves the low noise/high performance characteristics of this superb phono preamp.

In his latest revision of the PP-1, Albert Lukaschek has redesigned the regulation circuitry of the unit's power supply, bringing across-the-board improvements in the areas of clarity, focus, and bass control.
The net sonic result is a PP-1 of far greater refinement than any before. Tonal balance is slightly warmer than the previous versions, yet with far more resolution and extension. Bass is bigger and more solid; highs are effortless, open, transparent and totally devoid of smearing. Focus, soundstage depth and dimensionality, particularly on the edges of the soundstage, are much improved.
