What Reviewers Are Saying

"The amplifier’s 300 watts of output power can effortlessly drive any reasonable loudspeaker to realistic levels, creating an immersive listening experience that is simply brilliant."

— Best of High End

SOUND QUALITY PERFORMANCE 83/100

The available review portrays the 1162 as an exceptionally clean, controlled and powerful amplifier, particularly with demanding loudspeakers. It offers strong evidence on clarity and effortless output, but says little about tonal shading or spatial presentation.

Transparency Resolution

90/100

The reviewer describes power delivery with “precision and clarity” and says the design minimizes interference, allowing music to be heard without distraction. This points to a notably quiet, clean presentation, although there is no detailed discussion of low-level detail or comparative resolution.

Tonal Balance Musicality

75/100

The review calls the listening experience immersive and brilliant, but provides little direct description of tonal balance, timbre, warmth, neutrality, or long-term musical character. There is not enough evidence to determine whether the 1162 favors a particular tonal perspective.

Dynamics

93/100

Its 300W rating is described as effortlessly driving any reasonable loudspeaker to realistic levels, while the Smart Current bias circuit is credited with precise power delivery. The stated peak-power capability and protection arrangement further support the impression of substantial headroom and control.

Soundstage Imaging

75/100

The reviewer calls the experience immersive, but does not specifically discuss stage width, depth, image focus, layering, or three-dimensionality. Spatial performance is therefore not well documented in the available coverage.

Assessments of Build Quality, Usability, and Overall Propositions.

Build Quality

93/100

The 1162 is presented as a thoroughly engineered amplifier, with refined circuits and optimized mechanical execution. Dual DC-filtered transformers enclosed in a welded steel case are specifically credited with silent operation, while the robust protection circuitry, high-current speaker terminals, and IP/HTML integration indicate a carefully considered implementation.

Value for Money

85/100

At approximately $42,500–$45,000, the 1162 occupies an uncompromising high-end segment. The review is strongly positive about its engineering and performance, but does not compare it with similarly priced rivals or directly assess whether its asking price is especially compelling.
