IFH Series IFH-2120
When Clarity & Accuracy Is A Must..."1 ohm Stereo Stable"
The IFH series amplifiers were designed for anyone looking for a real world, seriously performing amplifier. The ever powerful IFH series high current amplifiers have not changed much in the past five years, which is very rare compared to a lot of other brands these days. These amps provide you with the finest in audiophile quality sound. High headroom, high quality crossovers give you super low noise, while adding no color to the audio signal. The crossovers are all SMT (Surface Mount Technology) level mini-cards which are mounted to the main board. This is a major advantage over other amplifiers because there is no chance for any radiated noise within the amplifier. The benefits are astounding! And like all other interfire amplifiers, all the IFH series amplifiers feature wide trace separate board outputs which eliminates any chance of radiated noise. The high current series amplifiers are one ohm stable, and are built to deliver some serious power to the speakers.
