Vitus Audio SM-025 Signature Monoblocks Debut

Vitus Audio has announced the SM-025 monoblock power amplifiers, adding a new model to its Signature Series and replacing the SM-011, which remained in the company’s range for more than a decade.

A New Signature Series Monoblock

The SM-025 arrives as a direct successor to the SM-011, one of Vitus Audio’s established monoblock power amplifiers. While the new amplifier retains the recognizable visual language associated with Vitus Audio components, the company has treated it as a major internal update rather than a cosmetic refresh.

The SM-011, released in 2014, was one of the first Vitus Audio amplifiers to make extensive use of surface-mount components in the output stage.

Reworked Internal Architecture

According to the supplied product information, the SM-025 features a significantly modernized construction. Vitus Audio has revised the internal architecture and incorporated selected engineering ideas developed for its flagship SIA-030 integrated amplifier.

The company has also positioned the SM-025 as an evolution in Class A performance, with the model described as doubling Class A power compared with its predecessor. No further output figures were provided in the supplied information.

Not a Sudden One-Off Launch

Although the SM-025 is now being presented as a Signature Series production model, it had already appeared in demonstrations before serial production began. That makes the amplifier less of a surprise unveiling and more the formal arrival of a design Vitus Audio had previously shown in public.

The Vitus Audio SM-011 amplifier delivered approximately 25 watts per channel into a nominal 8 ohm load and 50 watts into 4 ohms, after which it switched to Class AB.

The background also helps explain the scope of the changes: the SM-025 is not described simply as a replacement chassis for the SM-011, but as a new generation of the company’s monoblock concept within the Signature line.

Design Continuity With Technical Changes

Externally, Vitus Audio has maintained the familiar industrial design that identifies its electronics, suggesting that existing customers will find the SM-025 visually consistent with the rest of the brand’s components.

Inside, however, the amplifier is said to have received substantial changes, including engineering influenced by higher-tier work on the SIA-030. Vitus Audio has not provided pricing, market timing, or additional specifications in the supplied material.

The SM-025 marks an important update to Vitus Audio’s Signature Series amplification lineup, replacing a long-serving model while preserving the company’s established design identity.
