The Unico range of hybrid hi-fi electronics from Unison Research has garnered a strong reputation with audiophiles around the world in recent years. The new Unico 150 dual-mono integrated amplifier has been designed from the ground-up to take the mantle of flagship in the Unico range; superseding the well-established Unico 100 model.
“The Unico 150 amplifier has been designed to fulfil both high-end audiophile and highly scientific criteria. This dual-approach to development has led to the creation of a product that is completely different from anything else Unison Research has ever released, and the result is something truly unrivalled on the market; a powerful, great- sounding amplifier with only three active stages (two tube and one MOSFET stage)” says the press release from Henley Design who distribute the range in the UK.
The Unico 150 is an integrated amplifier designed to accommodate a variety of sources via its three RCA and two XLR pair inputs. It’s also designed to fit into most existing systems, with its fixed and variable RCA outputs as well as the bi-wirable speaker terminals. The large casework is built to the same standards as previous Unico designs, but the Unico 150 is the first to boast a new three-plate front fascia that adds an aesthetic enhancement over its predecessors. Operation is simple via the front-panel controls or the supplied RC2 system remote.
The Unico 150 uses a three-stage circuit and all of the gain – and with it the core sound character of the amplifier – is controlled by the first two Pure Class A tube stages. The input stage uses two ECC83 triodes in totem-pole configuration, while the driver stage uses two 6H30 triodes in totem-pole configuration for “near-flat distortion, minimal output impedance and well controlled gain”. A high- quality but entirely passive ALPS volume control and armoured input switching relays are used.
The whole pre-amplifier section is directly coupled to each channel’s MOSFET power stage to achieve a consistent, with optimal linearity achieved within 10 minutes of being switched on (nominal linearity is achieved in under a second). The Unico 150 has been designed to drive a wide-variety of loudspeakers.
The Unico 150 boasts purpose-selected power transformers and the power section has also been configured to give plenty of headroom for reliability.
The Unico 150 will be available in the UK from November 2015.
It will be available in Silver finish, or to special order in Black for a £100.00 surcharge.
