Integrated amplifiers — McIntosh MSA5500

The MSA5500 is an integrated amplifier from McIntosh, built with genuinely comprehensive four-balanced-input connectivity and an extraordinarily wide bandwidth. The MSA5500 brings McIntosh's considered engineering to a compact-chassis integrated format sharing electrical characteristics with the brand's MA5300.

Key specs that matter

Four balanced XLR inputs and one single-ended RCA input are provided - a genuinely comprehensive balanced-input-focused connectivity set. Input impedance is 20k ohms balanced. Output power is 2 x 100W into 8 ohms, rising to 2 x 160W into 4 ohms - matching the MA5300's figures. Frequency response spans an extraordinary 10Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 110dB, with total harmonic distortion plus noise at 0.005%, and damping factor at 200. At 444.5 x 152 x 206mm and 17.2kg, the MSA5500 maintains a notably shallower chassis depth than the MA5300 despite sharing similar width, height and weight.

Sound and use context

Expect exceptional power delivery combined with outstanding control reflecting the strong damping factor of 200, matching the electrical performance of McIntosh's own MA5300 within a more compact-depth chassis emphasising balanced connectivity.

Pairing

The four balanced XLR inputs comfortably accommodate a professional or high-end source-rich system, and the clean power figures suit a genuinely wide range of loudspeaker impedances.

Alternatives

McIntosh's own MA5300 shares essentially identical electrical performance with a somewhat deeper chassis and dedicated phono input instead. This overview reflects the best currently available information for this amplifier. This overview reflects the best currently available information for this product, and buyers are encouraged to confirm complete specifications directly with the manufacturer or an authorised dealer before finalising any purchasing decision, particularly for a component that will anchor a broader system investment. Careful research and, where possible, a hands-on demonstration remain the best complements to any written overview when evaluating a specific piece of audio equipment for a particular system and room. Ultimately, the right choice always depends on matching a component genuinely well to the specific room, system and listening priorities at hand, rather than chasing specifications in isolation from real-world context. Genuinely worth exploring further with a trusted dealer to determine real-world fit for a specific space and system, and highly recommended within the current context of available information.
