Preamplifiers — T+A P 3100 HV

The P 3100 HV is an accomplished preamplifier from T+A, part of the German brand's regularly updated High Voltage (HV) flagship series, receiving an improved toroidal transformer and an upgraded power supply for its digital section. The P 3100 HV brings T+A's most storied German engineering to a serious, high-voltage-topology preamplification format.

Key specs that matter

Four balanced and seven single-ended analogue inputs are provided, with one balanced and two single-ended outputs. Input impedance is 5,000 ohms balanced or 20,000 ohms single-ended, with output impedance at 50 ohms on both connections. Frequency response spans an exceptional 0.5Hz to 300,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is an excellent 108dB (unweighted) or 112dB, with total harmonic distortion plus noise under 0.001%. At 170 x 460 x 460mm and 28kg, the P 3100 HV maintains a substantial preamplifier chassis reflecting T+A's most accomplished current HV-series engineering.

Sound and use context

Expect exceptionally clean, uncoloured amplification reflecting the exceptional 300kHz upper bandwidth combined with the excellent signal-to-noise ratio and sub-0.001% distortion, with the improved toroidal transformer and upgraded digital-section power supply delivering meaningful refinement over the previous generation.

Pairing

The comprehensive four-balanced, seven-single-ended input configuration accommodates an extensive source collection, and T+A's own power-amplifier catalogue offers natural, brand-coherent pairings within the HV series.

Alternatives

T+A's own broader HV series offers related separates alternatives within the same considered high-voltage-topology engineering philosophy.
