You can earn loyalty points on every order you place on this website. If you select to create an account at checkout, your loyalty points will be saved and you can use these to discount future orders online.
Each product page shows you how many loyalty points you can earn when you order that item. Essentially, for each £1 you spend, you earn 1 loyalty point and for every 1 point earned, 1p will be added to your loyalty point balance (this is the same as some of the UK's biggest loyalty point cards). So for example, if you spend £500, you'll earn 500 loyalty points which can be used to discount a future order by £5.00.

Description
Unison Research's Unico 90 Integrated Amplifier sits near the top end of the Unico range borrowing much of its look and design from the flagship Unico 150 integrated amplifier.
Powerful
The dual mono design gives this amplifier more power and control of your music. Boasting 160W (4Ω) per channel the Unico 90 is capable of driving some of the most demanding loudspeakers with ease and poise.
Components
Featuring double triode totem pole ECC 83 and one parallel totem pole ECC81 triode valves per channel in the input stage and using high-quality German Mundorf components, Unico 90 has a unique circuit delivering 160W per channel.
Circuitry
This single stage due to the particular circuitry is able to amplify the input signal and directly drive the power stage. This amplifier has two stages, input stage and output stage and uses only local feedback.
Hybrid Amp
Unico 90 is a class A hybrid integrated amplifier with zero feedback, as the most precious valve amplifiers use only two stages. All of the gain and subsequently the "character" of the amp, is determined by the only tube stage made with ECC83 and ECC 81in particular multiple-parallel-totem-pole.
Connections
On the back of the Unico 90, there is broad flexibility with a selection of inputs including two balanced XLRs as well as standard RCA. There is also 4 + 4 speaker terminals allowing for bi-wiring and a subwoofer output to add even more depth and enthralment.
