The Unico 150 amplifier has been designed to suit both high-end audiophile and highly scientific criteria. Single 150 is an amplifier whose implementation follows audiophile and scientific criteria.
This approach has led to the creation of a new product is from Unison Research productions solid state or by any other amplifier proposed by the market. The power is developed in 3 stages: two stages of amplification to valves and a power stage mosfet .

To you listening and evaluation …

The heart of the circuit 150 Unique is its hybrid structure, the first 2 tube stages, pears triodes configured to have a limited gain and lower output impedance , thus eliminating the compensation stage.

The preamp section is passive and adopts an ALPS volume potentiometer armored 4 sections .

The springs are connected one at a time, from mass raising those not connected.

Dual mono amplifier with power capacity 400 + 400 consecutive VA. The final mosfet can handle power up to 1200W and currents up to + -50 amps, protected by calibrated circuits on 70%.

Unique 150 can accordingly drive speakers with minimum impedance less than 2 ohms.
All capacitors have low losses and high frequency. The polypropylene has been widely used 4 Mundorf capacity at very low impedenzasono used in each channel. Electrolytic of Italian Itelcond are doubles are a low stray inductance.
One 150 is an amplifier whose power numbers are a function of the desired sound results, and not the opposite.
