If you're looking to improve the quality of your sound system, the Nordost QSINE Enhancer is an ideal buy. This plug-in provides a unique solution that helps to reduce EMI noise and improve the audio/video performance of two-channel and home entertainment systems.

If you're looking to improve the quality of your sound system, the Nordost QWAVE Harmoniser is an ideal buy. This plug-in manipulates the sine wave by introducing a precise range of pulsed frequencies onto the AC line, clocked from the original 50 or 60 Hz waveform. As a result you will notice increased imagery and dimensionality to your sound and a more dimensional and vibrant picture from your AV system.
