Offered is „KW 750 inkl Power Supply + KW Pre“ by Musical Fidelity as second-hand device from the category „Pre- / Poweramp Combination“ on audio-markt.de - the online market place for high-end. The advert with the number 1531421140 ends on 13.11.2026 at 06:10 o'clock.
Condition good is reassuring here, and at €4,790 the ask looks fair to slightly firm against the current used market rather than a steal. A new-ish dealer listing shows this model at about €4,200 used, so this private-sale price is a touch above that benchmark and sits in the “reasonable if clean and complete” zone, not bargain territory.
What makes it worth considering is the sheer muscle: the kW 750 is conservatively rated at 750 Wpc into 8 ohms and 1,100 Wpc into 4 ohms, with the kind of grip and headroom that suits demanding speakers and big rooms. It’s a serious, well-regarded powerhouse, and if the amp is truly healthy, original, and includes the right packing/accessories, the slight premium can be justified; I’d just confirm service history and that it’s been operating quietly, since repairs on a unit like this are not casual.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Musical Fidelity, a British hi-fi icon, traces its roots to 1982 when clarinettist and audio enthusiast Antony Michaelson founded the company in London. Disillusioned with the sound quality of existing gear after his stint at predecessor Michaelson & Austin, he handcrafted his debut product—a minimalist preamplifier dubbed "The Preamp"—on his kitchen table. Paired with the quirky Dr. Thomas power amplifier, these designs disrupted the market with their bold aesthetics and sonic punch, establishing Michaelson’s experimental ethos from the outset.
The brand has long centered on amplifiers as its cornerstone, spanning integrated, power, phono, headphone, and preamp models renowned for Class-AB topology and innovative touches like Nuvistor tubes. It expanded into streaming players, DACs, CD players, Bluetooth receivers, all-in-one systems, and even headphones and turntables, always prioritizing musicality over convention. Unconventional industrial designs, from curved heatsinks to sculptural panels, became signatures, influencing competitors.
Positioned firmly in the high-end arena, Musical Fidelity commands respect among discerning audiophiles for its value-driven performance and soulful sound. Iconic models like the A1 and F-series endure as collector favorites, blending accessibility with premium engineering. Acquired by Austria’s Audio Tuning in 2018, it continues evolving under new stewardship while honoring its heritage as a boutique force in British hi-fi.
