Source AC Power Cable
$259.00 USD Example Sold out Sale


Think power cables don't make a difference? Think again.

The Source AC Power Cable is a remarkable upgrade to the power supply of any amplifier or audio component.

Solid IGL™ copper conductors replace the only stranded conductors in the power delivery system.

Hot and neutral conductors are composed of four isolated cores each in a helical array around the earth conductor.



High-purity proprietary IGL copper conductors for distortion-free midrange and
high frequencies.

Solid-core conductors eliminate the negative effects of strand interaction on the AC signal.

100% shielding blocks noise and bleeds to ground.


The Source comes with standard with a Wattgate™ 320i IEC connector on the output side, and a Wattgate 5266i US Wall Plug. Both are cryogenically treated.

Our Proprietary high-purity IGL copper conductors for distortion-free midrange and high frequencies.

The solid-core center conductor eliminates the negative effects of strand interaction on the audio signal.

20 awg conductor size keeps skin-effect distortions outside the audio spectrum while offering ample cross-sectional area.

Parallel-run shield provides 98% coverage with minimal crosstalk.

Coaxial geometry with low capacitance.

Carbon-loaded extrusion for protection from triboelectric noise.




The inside of the tip of the SIS plug is carefully machined to have “threads” of a precise size and pitch. These threads cut and re-shape the soft conductor of the Monorail cable when turned around it several times.

When you push the prepared cable into the SIS plug, the soft copper will find the hole. When you turn the plug 1 or 2 times the harder brass core of the plug will catch and cut into the copper conductor. When you feel this happen you put the cap in place and screw the SIS plug into the cap.

This action turns the soft copper deeper into the SIS core – Mashes the ground up against the SIS body to make ground contact (airtight as the copper is deformed inside pushing air from the connection). This seals the jacket at the exit tightly so that the cable will not come loose from the plug and the cap will not come loose from the plug body. When finished the tip/core connection with the Monorail is also air-tight and in many ways better than a soldered connection. If you unscrew the SIS plug and remove the Monorail cable you can see the soft copper has been shaped to meet with the SIS core.





1) REMOVE the thin black (conductive) skin from around the white insulation. If it touches where the conductor needs to enter, you’ll create a complete short or partial short with weak signal.

2) Do not cut up your cable into short pieces before attaching the plugs. Instead attach the first plug to your long/entire supply of cable. Measure the length required to the other plug. Cut and attach the second plug to complete your cable. Rinse, repeat.

3) Wear rubber gloves to get a good grip and spare sore fingers when closing tight.






Push the cable into the plug and when you seat the core, rotate the plug about 10-12 full revolutions (straight plug only). This will simultaneously thread the copper core into the tip of the plug and screw the body of the plug onto the cable jacket. You only need the jacket to enter the plug a few millimeters.


The ESP-RA™ is the first solderable 1/4" phone connector from Evidence Audio and designed (like all of our products) with the primary purpose to sound demonstrably better than anything in its class.

What class does it fall in?  Its compact size and angled format makes it especially suitable for use with smaller cables on pedalboards specifically. Cables with an outer diameter of 4 mm, or around 0.155".

The current flood of plugs used to solder patch cables for a guitar pedalboard typically use a steel nail or pot metal to conduct the audio signal. Ferrous. Magnetic. While these plugs are compact for pedalboards, they cut corners by using inferior metals to carry the sound. They offer greater affordability yet greatly reduced audio quality.


The contact points of the ESP-RA™ are machined from a high-copper-content brass. Brass offers the appropriate hardness and strength required for a connector with very good conductivity to minimize distortions caused by the cable the plugs are used on.


The form factor is akin to a "pancake" style plug, with a patent-pending closure system that allows for the plug to be assembled with one screw instead of two. This allows for a smaller form-factor as well as reduced assembly time. 


Width 16 mm | Height 25 mm | Depth 8 mm
