Unison Research® is celebrating with a special edition of our most successful products: Simply Italy, Triode 25 and S6. The Black Edition boasts advanced technical and sonic performance, featuring a new cosmetic design with a piano black wood front panel, black gun metal finish, and updated lettering graphics.

In the Simply Italy Black Edition, we’ve introduced a new technical solution: electronic polarization. This solution ensures the stable working point of the power valve throughout its lifespan, eliminating the need for auto-bias. This design allows us to extract the best performance from the KT77 valve and provide maximum power to the valve.

We’ve also redesigned the output transformer, now featuring a refined 5-section design, to further enhance the sound quality from the KT77.

Additionally, we’ve revised the circuitry in the signal path and power management. The input selection circuit now utilizes the same advanced technology found in our most premium equipment. We’ve also paid extreme attention to the design of ground paths and channel separation to ensure optimal performance.

The new features introduced in the Simply Italy Black Edition amplifier are:

• Electronic bias adjustment
• Unfiltered SUB output that maintains the sound timbre of the amplifier designed to be connected to active subwoofer
• Input selection circuit implemented using micro relays and Return GND technology
• In addition to the 3 analogue inputs, inside the amplifier there’s the new DAC3 which adds 3 more digital inputs; USB (PCM up to 384 kHz, DSD native up to 256x e DoP up to 128x), Tos-link e SPDIF up to 192 kHz as standard
