The Linebacker Sovereign
 Introducing: The Linebacker Sovereign

  • Mega Sized pure Silver Super Enhanced Ground Plane
  • 1.5m Cosmos Power Cable
  • ​Ultra Heavy Duty Chassis with Dual Stage Passive Filtering  
  • Massive Vibration Damping Treatment
  • Cast Silver Duelund Capacitor for Ultra Pure High Frequency Extension
  • Bocchino male and female IEC connectors
  • Optimized Damping and Noise Absorption Formula

The next order of magnitude in noise reduction. If you think you know the sound of your favorite vocalist's voice, think again. With the PranaWire Linebacker Sovereign micro dynamics and micro colors are delineated in a way that defies description. It is as though the sensitivity of the recording microphone had been increased by a factor of ten, especially in its ability to pick up the finest details. All frequencies are improved. Everything is cleaner, clearer, more dynamic, richer more musical and more engaging. The Linebacker Sovereign will leave you in wonderment.

The Linebacker XE Eliminates Noise to Below the Noise Level of the Measuring Equipment:

Top Row: Ambient and Chassis Noise before Linebacker XE 2 and after Linebacker XE - a greater than 60 db reduction
​(A 1000-fold reduction)

Bottom Row: Power Line Noise before and after Linebacker XE - a greater than 60 db reduction (A 1000-fold reduction). Noise reduction is measurable to the level of the noise of the measuring equipment.

Noise was measured to 175 Megahertz down to TV, FM audio range and zero Hz with the preponderance of noise showing between 45 and 80 Megahertz.

Ambient and chassis noise refers to ambient noise picked up by both the chassis of the Linebacker itself and the cable feeding the Linebacker acting as an antenna. Even though the Linebacker is bathed in a sea of EMI, there is effectively no noise delivered to the next component at the cable IEC end.

A word about why the Linebacker is an essential part of a true high end system:

​As demonstrated above, the Linebacker will prevent a prodigious amount of high frequency noise from ever reaching your component. This is of vital importance. Though common understanding of power supply design suggests that noise will be attenuated before impinging on the circuit, we know this is not the case, especially with regard to high frequency noise. Such noise entering the component will be returned to the component via its output cable in a backward motion more or less out of phase, modified in frequency from the original and enhanced by any noise accumulated due to the fact that the cable attracts noise like an antenna. This modified returning noise combines with the noise already present in the component causing beating to form, just as when two strings are slightly out of tune. This beating will be directly proportional to the difference in frequency causing distortion in the audible spectrum. Since it is expected that this noise covers a wide frequency range the potential for a true muddle of beating frequencies is exponentially high.

That is why when a single Linebacker is placed in a system the resulting improvement in clarity and freedom from subtle and not so subtle distortion is on a very high order of magnitude. Each additional Linebacker in a system offers another 100% efficacy in treating the additional component.

 Linebacker OL, GP and SE Models

PicturePranaWire Linebacker GP
The Linebacker In-Line Power Filter offers unprecedented reduction of noise. It is utterly transformative.

The Linebacker is a completely passive in-line power filter that works on several major fronts:

  • It effectively absorbs massive amounts of parasitic and self-generated noise on power cable lines and prevents it from entering into the component it is plugged into It prevents environmental noise from entering the system through the mains It's maximally damped structure and cable quell cable, connector and airborne resonances before they enter the system.

Linebacker OL

  • Superior Power Cable Design (10 gauge 7N Pure Copper Conductors) 
  • Custom damped Oyaide C-004 IEC Female Connector 
  • Highly damped chassis and IEC Male connector 
  • Massive amounts of carefully chosen noise absorbing materials
  • Super Enhanced Ground Plane (SEGP) to absorb noise away from the ground plane of components 


Linebacker GP and SE:

  • Satori Power Cable design (7 gauge Silver/OCC copper conductors) whose internal architecture and materials implementation are inherently noise canceling 
  • Custom damped Oyaide F1 IEC Female Connector 
  • Highly damped chassis and IEC Male connector 
  • Massive amounts of carefully chosen noise absorbing materials
  • Super Enhanced Ground Plane (SEGP) to absorb noise away from the ground plane of components 
  • GP has Copper Ground Plane and Copper Wire, SE has Pure Silver Ground Plane and Silver Wire

The Linebacker will remove noise that you did not even know was there and render an extremely solid and palpably holographic sound stage. Bass is dramatically improved with new found focus. The Linebacker is a truly transformative device!

Five Models:

  • The Linebacker OL - Full Range Performance at an affordable price
  • The Linebacker GP with Pure Copper SEGP - Full Range Tuning
  • The Linebacker SE with Pure Silver SEGP - Full Range Tuning
  • The Linebacker XE - The Extreme - with massive Pure Silver SEGP - Ultimate Noise Obliteration
  • The Linebacker Sovereign - Enter the Realm of the Sublime

"Pure Joy"

"Dulce Pontes always is excellent to assess system quality. Her voice can be piercing and crack the enamel right off your teeth if anything is wrong. With the Linebacker in place, her Momentos album was pure joy...In our tests through various setups with their inherent noise-generating capabilities plus external noise sources, each time the Linebacker was included, calmness and quiet entered the scene and unrest and indecision left the building." Marja & Henk, 6Moons Audio September 2012
