Nordost QSine AC ENHANCER
The QSINE enhances the AC signal in a sound system by introducing a specific frequency field onto the circuit path. This frequency field indirectly reshapes the sine wave, which, in turn, lowers the effects of EMI noise embedded into the AC power, positively impacting the listener’s perception of the musical signal. Introducing the QSINE into your sound system brings about several distinct benefits
- A lowered perceived noise
- An increase in the clarity, detail, and pacing of musical reproduction
- A reduction of EMI on the AC line
- Greater musicality and improved tonal balance
