Nordost QRT Plug-In Modules

Direct AC Parallel Enhancers & Harmonizers | Brisbane HiFi Specialist

The Nordost QRT Plug-In Modules including QSINE, QWAVE  and QV2/QVIBE are compact AC accessories designed to operate in parallel with the mains supply rather than placing filtering components in series with the equipment's power path.

Installed directly into an unused AC wall outlet or compatible distribution block, these QRT devices are intended to optimize different aspects of the electrical environment surrounding high-performance audio and AV systems.

At Brisbane HiFi, we recommend the Nordost QRT range for audiophiles and home cinema enthusiasts looking to explore incremental system optimization without introducing a conventional series-filter power conditioner.

Overview of the QRT Plug-In Lineup

QSINE — AC Sine Wave Enhancer

The QSINE is an active QRT device designed to operate in parallel with the AC supply.

Its purpose is to optimize the electrical environment by addressing unwanted high-frequency noise and mains artifacts.

Potential system benefits include:

• Lower perceived noise floor
• Greater vocal clarity
• Improved transient smoothness
• More natural high-frequency presentation

QWAVE — AC Line Harmonizer

The QWAVE uses tuned frequency generation intended to interact with the 50/60 Hz AC supply.

It is designed to enhance:

• Three-dimensional imaging
• Soundstage depth
• Instrumental presence
• Video contrast and black levels

Making it particularly interesting in combined audio/video systems.

QV2 / QVIBE — Active AC Line Harmonizer

The QV2/QVIBE uses active circuitry housed in a carbon-fiber enclosure to generate a tuned frequency field around the AC line.

It is designed to influence the system's electrical environment with an emphasis on:

• Midrange texture
• Leading-edge smoothness
• Instrumental decay
• Image stability

Choosing Between the QRT Modules

For a high-end system, the modules serve different roles:

• QSINE – Focus on mains waveform and electrical noise optimization.
• QWAVE – Emphasis on spatial presentation and combined audio/video performance.
• QV2/QVIBE – Tuned-field approach with emphasis on tonal texture and image stability.

The QRT modules can also be used cumulatively where the system and available AC outlets permit.
