Усилители мощности моно — MasterSound PF100 litz edition

The PF100 Litz Edition is a mono power amplifier from MasterSound, built with a wide rated bandwidth typical of a tube design. This model represents MasterSound's dedicated mono power amplifier offering, extending the brand's characteristic tube engineering into a per-channel format for a system built around separate preamplification.

Position in line

It sits alongside the Booster in MasterSound's power amplifier range as a related design. This positioning alongside the Booster suggests MasterSound offers a small, focused catalogue of mono power amplifiers, each likely reflecting a distinct output stage approach or tube complement.

Key specs that matter

Rated output is 107 W into both 8 and 4 ohms. Rated bandwidth is 12 Hz to 90 kHz. At 540 x 470 x 270 mm and 50 kg it is a substantial, heavy monoblock, consistent with a serious tube-based power supply and output transformer configuration.

Sound and use context

Expect the open, harmonically rich character typical of a substantial tube monoblock design - an engaging performer reflecting MasterSound's broader house philosophy of prioritising tonal richness alongside measured performance.

Pairing

Loudspeaker sensitivity matters given the amplifier's tube-typical output level and construction, so a reasonably efficient loudspeaker pairing is worth prioritising for the best results.

Alternatives

The Booster is worth comparing directly with a specialist dealer given the brand's relatively limited international distribution outside Italy. Given the substantial 50 kg weight and tube-based construction, adequate ventilation space around the chassis is essential for reliable long-term operation. MasterSound relatively limited international distribution outside Italy means sourcing a dealer with genuine hands-on experience of the brand is worth the extra research effort before committing to a purchase. Overall this remains an engaging tube monoblock reflecting MasterSound characteristic Italian voicing. A dealer visit remains the simplest way to compare this model against the closely related Booster. Cable and stand choices matter far less here than getting the basic loudspeaker sensitivity match right. Adequate mains supply is also worth confirming given the substantial transformer inside. Overall this remains an engaging choice for a tube enthusiast.
