Stereo amplifier using Hypex, N-Core Class D amplification. It delivers 2 x 500W and mounted in our custom made black enclosure.



The IOM NCore 500m is an affordable 500W stereo amplifier based on the Hypex nc502mp board. Mp stands for mains powered; the powersupply of the amplifier is integrated with the amp, both on the same board. That is why we call it the 500m. It’s housed in a full aluminum chassis with balanced & unbalanced inputs (selectable).

There is an optional 2 * 16 amp switch board available that protects your speakers for undesired switch-on & switch-off phenomena; the speakers are connected to the amplifier with a dely and are disconnected just before the amplifier is turned off. The amp is turned off with a delay of 1 second.

    Communication & shipping were prompt. The amp itself is wonderful; feels very solid without being overwhelmingly large and it’s breathed new life into speakers I was thinking about selling and am now enjoying more than ever. Incredible value, great product, highly recommend.

    The amp has arrived. Short and sweet: “Sehr geil:)”

    The decision wasn’t difficult. Hello IOM Hypex, bye bye Rotel…

    Op 12 mei de IOM500M aangeschaft als upgrade van de Bluesound Powernode 2i. Eerst nog de powernode als voorversterker gebruikt ondanks deze zeer ongebruikelijke aansluiting was toch direct merkbaar dat laag, volume en transparantie aanmerkelijk verbeterde.

    Daarna de nieuwe Arendal’s 1723 THX towers aangesloten en weer een grote update in geluid transparantie en spreiding en strak laag.

    Nu de power node er is tussen uitgehaald en de versterker rechtstreeks met een WIIM mini verbonden en ondanks TI dac weer een verbetering met name in het laag.

    Het wachten is nu de nieuwe Dac en streamer dit moet een feestje worden.

    Al met al zeer tevreden met de versterker en met de service van IOM.
