Mastersound's in-house transformers are famous and special in their own way. Most transformers are heavy because of the amount of metal, but Mastersound's go a little further.
Mastersound’s designer demands Litz wire windings, insists on a no-solder policy inside the transformer, and precisely specifies the number of windings. They then pot the transformer inside a can filled with a resin and gravel mix. This damps the transformer perfectly, and adds a lot of mass, as well as acting as a security measure to protect their proprietary design. The transformer will be destroyed if attempts are made to remove the transformer from its casing.
All Mastersound amplifiers are Zero Feedback, Class-A based designs. Each product is hand-built in stages. Mastersound recommends a minimum of 200 hours burn-in to reach peak performance.
All amplifiers are Single-Ended or Parallel Single-Ended designs, no push-pull. Parallel Single-Ended allows more power while retaining the character of a Single-Ended design - like a fast response and rich harmonic content.
Since 1993, Mastersound valve amplifiers from Italy have been beguiling many music lovers around the world.
