Part of our classic line of tube amplifiers that include the Sinfonia and the Performance, the Preludio integrated amplifier continues the technical approach, sound and aesthetics of its larger siblings. While the Preludio’s appearance is certainly gorgeous, it is also extremely reliable due to its unique design solutions, quality materials and adherence to the highest of standards.

Preludio is an integrated tube amplifier that maintains the distinctive technical elements, sound characteristics and stunning looks that Unison Research is known for. It bears an obvious resemblance to the higher-end Sinfonia and Performance amplifiers, but maintains a very appealing price for a product of such prestige.

Using double triode ECC82 valves the Preludio’s pre and power amplification gives an exclusively valve amp performance that delivers a natural and dynamic presentation.

Special attention has been dedicated to the design of the output stage, which is based on two KT88 tubes. Tried and extensively tested, the bias setting of the KT88s ensures the best sound performance even after many years, and also contributes to minimising the time it takes for the tubes to warm up to optimal temperature.

Every part of the Preludio has been thoroughly thought out from the circuit boards to the control knobs to offer a premium design and a premium sound. For example, the top-plate is not just good looking, it's made from amagnetic stainless steel with low heat conduction to stop the heat generated by the KT-88s interfering with the internal circuitry.

Key Features:

  • Stylish tube integrated amplifier
  • Dedicated pre, power and output stages per channel
  • Tube-based Class A amplification
  • 5 gold platted inputs
  • High quality powered design
  • KT88 tubes in the output stage
  • RC2 remote included
  • Premium Cherry Wood finish

Glow and fight crepey neck!
Size: 0.42 Fl Oz (Pack of 6)
Favorite in my routine. I love Vaseline lotions and this is a perfect last step to my neck and hands every morning. Gives a boost of hydration and a nice glow to my neck. I think this is keeping me from crepey neck skin. Gotta fight that ladies! I use this several times a day and have it to all my friends for Xmas.

Something is different
Size: 0.42 Fl Oz (Pack of 6)
Product seems okay, but something has changed about it. Perhaps a different ingredient. Something different about the smell and texture. Still smells good, not greesy, and absorbs into skin like the past products I have purchased, but definitely something has changed.
