WHAT HI-FI?
Marantz MM7025 maximises the pleasure derived from the most enjoyable – and most fleeting – of musical moments.
The Marantz MM7025 is a 2-channel power amplifier built to add real muscle to a preamp, AV receiver, or other audio source, delivering 140 watts per channel through a discrete Class A/B design with current feedback topology. A large-capacity EI power transformer with 30,000 µF of energy storage supplies the current headroom needed for dynamic peaks without strain, and a wide 8Hz-100kHz frequency response paired with a 105dB signal-to-noise ratio keeps the sound clean and detailed across the full audible range. Eight channels of balanced and unbalanced inputs, switchable via a front selector, make it easy to integrate into an existing multi-source system rather than dedicating it to a single input. Tuned by Marantz's Sound Master team for an expansive soundstage and superior clarity, it's built for listeners who want to separate amplification from preamp or source duties for better overall system performance. Backed by a 3-year warranty, it's a solid choice for anyone upgrading a two-channel hi-fi or home theater front stage beyond what a receiver's built-in amplification can deliver.
