Nordost’s QRT AC Enhancer is designed to improve upon the poor-quality AC that negatively affects the audio/video performance of two-channel and home entertainment systems. Despite their overarching synergy, each Nordost plug-in can be used as a stand-alone product, providing its own, unique solution to the “AC problem”.
Nordost's AC Enhancer, the QKOIL generates a field created by its Micro Mono-Filament-made Load Resonating Coil (LRC), the QSINE reshapes the sine wave by introducing specific frequency fields onto the circuit path which, in turn, lowers the effects of EMI noise embedded into the AC power
Once integrated into a hi-fi system, listeners will notice:
• A reduction of EMI on the AC line
• A lower noise floor
• An increase in the clarity, detail, and pacing of musical reproduction
• Increased imagery and dimensionality of the soundstage
• Greater musicality and improved tonal balance
• A deeper, more dimensional and vibrant picture on AV Systems
Hearing is believing
"In my scribbled notes I found many expressions like “a bit, almost unnoticeably, perhaps, ever so slightly”. This leads to a logical conclusion that removing the QRTs from the system should be almost unnoticeable, with perhaps a bit less accomplished sound that will be just slightly inferior to QRT-powered system. Oops! Not at all. The moment the QRTs were unplugged the music became stressed, mechanically rushed and confused. The music lost its flow and it lost its life." Audiodrom read the review
"The affect was immediate and outstanding"
