Unison Research Unico Nuovo Hybrid Integrated Stereo Amplifier at Vinyl Sound Buffalo, NY USA

The Unico Nuovo is a hybrid integrated stereo amplifier from Unison Research (Treviso, Italy), available at Vinyl Sound in Buffalo, NY, USA. The most accessible entry point into Unison Research's Unico hybrid amplifier line, the Unico Nuovo uses a parallel ECC83 tube input stage operating in pure Class A to feed a Dynamic Class A MOSFET complementary output stage, producing 95 watts per channel at 8 ohms. With a frequency response extending to -0.5 dB at 100 kHz, 10 dB of negative feedback, and a THD of 0.15% at 10 W/1 kHz, the Unico Nuovo delivers the Unico family's characteristic blend of tube warmth and solid-state control. Five RCA line inputs, a tape output, and a volume-controlled subwoofer output provide practical system flexibility, while 4+4 bi-wiring output terminals accommodate bi-wired loudspeaker configurations.

Tube Input, MOSFET Output, and Dynamic Class A

The Unico Nuovo's circuit follows the same fundamental hybrid philosophy as the larger Unico 90 and Unico 150: a pure Class A tube gain stage establishes the amplifier's sonic character, and a solid-state output stage provides the power and current delivery. The ECC83 (12AX7) input stage uses a parallel valve configuration -- placing multiple device sections in parallel to reduce noise and output impedance relative to a single-section topology. The Dynamic Class A MOSFET output stage adjusts its bias current in response to signal demand, maintaining Class A operating conditions across the normal listening range while managing heat dissipation at higher output levels. A 10 dB feedback factor and a damping factor above 50 ensure that the Unico Nuovo maintains frequency response accuracy and bass control with the majority of loudspeaker loads likely to be encountered in practice.

Five Inputs, Subwoofer Output, and Bi-Wiring Capability

The Unico Nuovo's five RCA line inputs accommodate CD players, DACs, streamers, turntable phono preamps, and other line-level sources, with one position optionally configurable as a phono input. An IR remote control governs volume from the listening position. The tape output enables recording from any selected source. The volume-controlled subwoofer RCA output tracks the main volume control proportionally, ensuring bass level consistency when the Unico Nuovo is used with a powered subwoofer. Four pairs of speaker binding posts (4+4) support bi-wired connections to the main loudspeakers. At 43.5 x 9.5 x 43 cm and 16 kg, the Unico Nuovo is the most compact amplifier in the Unico series, fitting into standard equipment racks without the depth or height demands of the Unico 90 or Unico 150.

Key Features

• 95 W/ch at 8 ohm: Sufficient power for a wide range of contemporary loudspeaker designs in small to medium listening rooms.
• ECC83 Parallel Tube Input Stage: Pure Class A tube gain stage in parallel configuration establishes the amplifier's sonic character ahead of the MOSFET output stage.
• Dynamic Class A MOSFET Output: Thermally managed Class A biasing in the MOSFET output stage maintains Class A linearity across normal listening levels.
• -0.5 dB at 100 kHz Frequency Response: Extended bandwidth accommodates high-resolution audio content at sampling rates beyond the standard 44.1 kHz CD format.
• Five RCA Line Inputs (one optionally phono): Comprehensive source connectivity with optional internal MM/MC phono stage for turntable use.
• Volume-Controlled Subwoofer Output: RCA subwoofer output with volume tracking for powered bass supplement integration.
• Damping Factor above 50: High damping factor maintains bass definition and frequency response accuracy with complex loudspeaker impedance curves.
• 4+4 Bi-Wiring Output Terminals: Eight binding posts support bi-wired loudspeaker connections for enhanced driver separation.

Frequently Asked Questions

What is the Unison Research Unico Nuovo?

The Unison Research Unico Nuovo is a hybrid integrated stereo amplifier from Treviso, Italy, using a parallel ECC83 tube input stage in pure Class A feeding a Dynamic Class A MOSFET output stage to produce 95 watts per channel at 8 ohms. It has a frequency response of -0.5 dB at 100 kHz, five RCA inputs with optional phono, a volume-controlled subwoofer output, and 4+4 bi-wiring speaker terminals.

How does the Unico Nuovo compare to the Unison Research Unico Primo?

The Unico Nuovo produces 95 W/ch at 8 ohms using a parallel ECC83 tube input with Dynamic Class A MOSFET output, and includes five line inputs with optional phono, a subwoofer output, and 4+4 bi-wiring terminals. The Unico Primo produces 80 W/ch using a single ECC83 tube with Dynamic Class A MOSFET output, includes five line inputs plus one tape input and a subwoofer output, and uses a 10 dB feedback factor identically to the Nuovo. The Unico Nuovo's parallel tube input and higher output power (95 W vs 80 W) are its primary advantages; the Unico Primo is the lighter and lower-power option at 31 lbs vs the Nuovo's 16 kg.

Can the Unico Nuovo accommodate a turntable?

Yes, with an optional internal phono stage. One of the five RCA line input positions on the Unico Nuovo can be configured at the factory as a phono input for moving-magnet or moving-coil cartridges. Alternatively, an external phono preamplifier such as the Unison Research Simply Phono can be connected to one of the remaining RCA line inputs.
