Solo power amplifier

The UNI and SOLO are Ologe’s power amplifier and pre-amp. Adjustable to parameters such as slew rate and feedback, both are designed to be as fundamentally accurate as possible. As Ivan Lee, chief obsessionist at Ologe puts it “Our products deliver the truth only. We believe that music is a precision combination of notes. Music should be heard as it was recorded… Most audiophiles want their audio devices to embellish the audio, but all we want is the truth.”
