Phonostages — Violectric PPA V790

The PPA V790 is a phono preamplifier from Violectric, built with a rich set of both balanced and single-ended inputs. Violectric is generally better known for headphone amplifiers within the professional and enthusiast audio community, so this phono stage represents an application of that same precision-engineering approach to a different signal chain role.

Key specs that matter

Three balanced and three single-ended inputs are provided, an unusually generous connectivity set for a phono preamplifier, suggesting a design intended to serve as a central hub for multiple turntables or tonearms rather than a single dedicated source. Output impedance is 1 ohm, an exceptionally low figure that should drive long cable runs or a demanding preamplifier input with essentially no signal loss or high-frequency roll-off. Playback EQ curve accuracy is specified at 0.1 dB, a tight tolerance that speaks to careful attention paid to the RIAA equalisation curve's precision across the whole frequency range rather than just at a handful of reference points.

Sound and use context

Expect a precisely engineered presentation with tightly specified RIAA equalisation accuracy and a very low output impedance for driving long cable runs cleanly - the combination of these two figures suggests a phono stage built to measurement-led standards rather than a more loosely voiced, character-driven design philosophy.

Pairing

The rich balanced and single-ended input set covers multiple turntables or a turntable plus a second phono source, a genuine practical advantage for anyone running more than one analogue front end.

Alternatives

Violectric's broader range includes headphone amplifiers and DACs for a system built around the same brand, worth considering for a listener who values having a single manufacturer's design philosophy across the whole electronics chain. The rich balanced and single-ended connectivity here suggests a design intended less for a simple single-turntable household and more for a serious analogue enthusiast running multiple decks, tonearms or even a reel-to-reel machine through a shared phono-equalisation stage, since few casual listeners need six separate inputs on one unit. Given the very low 1 ohm output impedance, this preamplifier should have no trouble driving even an unusually long cable run to a distant power amplifier without measurable signal degradation.
