What Is a Power Amplifier – and Why Does It Matter?
Every music system needs an amplifier — it’s the part that makes your music powerful enough to move your speakers. You’ll find one inside a TV, a portable Bluetooth speaker, or your car stereo. Without it, all you’d hear is a very faint signal.
Today, more and more high-quality audio products — like music streamers, DACs, or preamps — are built without an amplifier inside. That’s actually good news: it gives you the freedom to pair them with a dedicated, high-performance power amplifier that delivers cleaner sound, more control, and far better dynamics than the built-in kind.
This is exactly where IOM’s Brick-line comes in. Designed for music lovers who want that extra step in realism and musical enjoyment, our amplifiers provide the pure, stable power your speakers need. The result is sound that’s not just louder, but richer, clearer, and more emotionally engaging.
And for true high-end audio enthusiasts, we take things even further with our IOM 500 Mono and IOM 500 stereo. Based on cutting-edge Hypex NCx500 technology, these amplifiers deliver exceptional resolution, effortless dynamics, and absolute control — the ultimate choice for those who demand nothing less than reference-grade performance.
For Wiim Ultra owners, we’ve also created the IOM Ultra — a perfectly matched, beautifully designed amplifier that blends seamlessly with your Wiim setup while delivering the same IOM sound quality.
Whether you’re upgrading from an all-in-one system or building your first true hi-fi setup, an IOM amplifier is the key that unlocks your music’s full potential.
How to choose your amp; range build up:
IOM Brick mono 250
Our range is starting with an amplifier named IOM Brick Mono 250. A basic but high quality mono 250W amplifier with RCA & XLR input. Volume control is done by controlling the level of the input signal: it has a fixed gain.
For a stereo system you need two of these Brick mono’s; one for the left channel and one for the right channel. Also suitable to upgrade your cinema AVR in the case you want more clean power.
