Many of our loyal Unison Research customers requested that we create a tube amplifier capable of output power well above all our previous achievements. To address this need, the design team created our flagship Unison Research amplifier, the Reference monoblocks. This amplifier is truly the culmination of all of our experience derived from years and years of valve amplifier design.
