Интегральные усилители — Vitus Audio SIA-030

The SIA-030 is an integrated amplifier from Vitus Audio, built with a hybrid class AB and class A output stage and an exceptionally wide rated bandwidth. Vitus Audio is a Danish manufacturer with a serious reputation for high-end electronics engineering, and the SIA-030 represents a substantial expression of that broader house philosophy.

Key specs that matter

Three balanced and two single-ended inputs are provided. Input sensitivity is 8000 mV, a notably high figure. Input impedance is 10,000 ohms for both connections. Output power combines 200 W class AB with 30 W class A into 8 ohms, doubling to 400 W class AB with 60 W class A into 4 ohms - this hybrid approach lets the amplifier run in pure class A at lower listening levels before switching to class AB for higher demands. Rated bandwidth is an extraordinary 0 Hz to 800 000 Hz. Signal-to-noise exceeds 120 dB with distortion under 0.01%. At 270 x 435 x 523 mm and 63 kg it is an exceptionally heavy chassis.

Sound and use context

Expect an engaging presentation combining class A warmth at typical listening levels with class AB headroom for demanding passages - a sophisticated hybrid approach reflecting Vitus Audio's characteristic Danish engineering ambition.

Pairing

The three balanced and two single-ended inputs cover an extensive source lineup, and the hybrid output stage suits both efficient and demanding loudspeakers across a wide range of listening levels.

Alternatives

Vitus Audio's broader electronics range, including the MP-P201 Mk.III phono stage, forms a natural partner for a system built around this amplifier, worth pairing together for a coherently voiced, Danish-engineered signal chain. Given the exceptional 63 kg weight, professional delivery and a solid, well-supported installation surface are both essential considerations before this amplifier arrives. Vitus Audio relatively specialist dealer network compared with more mainstream brands means arranging a proper demonstration is worth the extra research effort, and adequate ventilation space around the chassis also helps this substantial hybrid design run reliably. Overall this remains a sophisticated hybrid choice reflecting Vitus Audio Danish engineering ambition. A dealer visit remains the simplest way to compare current pricing across Vitus Audio electronics catalogue. A dealer demonstration remains worthwhile before committing to any specific purchase.
