The Unico 150 has a two-stage tube preamp on ECC83 and 6H30 triodes operating in Class A, and output stages on custom-made complementary field-effect transistors (four pairs per channel) operating in A/B mode.
The Unico Due integrated amplifier has replaced the proven Unico Secondo, but differs from it very significantly. The changes affected almost all elements of the scheme. In the pre-amp section of the hybrid device, two ECC83 dual triodes operate, selected based on the results of long listening sessions. The power amplifier is built on MOSFET transistors and outputs up to 100 watts at 8 ohms.
This is a hybrid integrated amplifier, which is an evolution of a popular European brand. Among the innovations: AC connection by buy-waring, MM/MS phono corrector with passive RIAA circuits on HF (audiophile solution). All amplifier circuits are optimized by repeated listening.
Primo is an integrated stereo amplifier, which is a perfect example of the Italian style. Elegant lines and details, carefully thought-out proportions and surface treatment have been universally recognized. The robust design, careful selection of components and precise assembly have concentrated all the experience, knowledge and ambitions to create audio technology in a small amplifier.
According to the manufacturer, the Unison Research Triode 25 Black Edition has an optimized amplifier circuit - both in the signal path and in the power supply.
