Integrated amplifiers — MasterSound Duetrenta

The Duetrenta is a tube integrated amplifier with phono from MasterSound, an Italian manufacturer known for considered tube-circuit engineering, built with comprehensive four-input connectivity. The Duetrenta brings MasterSound's considered engineering to a complete integrated chassis.

Key specs that matter

Three single-ended inputs plus a dedicated phono input are provided. Input impedance is 50k ohms single-ended. Output power is 2 x 33W into 8 ohms - a modest figure consistent with a tube-based circuit topology prioritising tonal character. Frequency response spans a wide 8Hz to 40,000Hz within plus-or-minus 3dB. At 490 x 330 x 230mm and 33kg, the Duetrenta's considerable weight relative to its modest output reflects serious output transformer and power-supply componentry typical of quality tube amplifier designs.

Sound and use context

Expect the rich, harmonically engaging tonal character genuine tube-based circuit topology is broadly celebrated for, with the modest 33W-per-channel output demanding efficient loudspeakers to reach satisfying volumes.

Pairing

The built-in phono input covers a turntable directly, and the modest 33W output pairs best with efficient, high-sensitivity loudspeakers.

Alternatives

MasterSound's own Evo 300B offers a more powerful alternative sharing similar tube-informed engineering philosophy within the same broader catalogue.
