AudioQuest Big Sur
Stereo interconnect cable with RCA plugs (5 meters/16.4 feet)
Our take on the AudioQuest Big Sur by Crutchfield's James Ralston
"Do no harm!" AudioQuest has been creating high-performance audio cables for more than 30 years, guided by this simple mantra. In AQ's view, the perfect cable would be one that adds nothing no noise, no distortion to the original signal. With its Big Sur cables, AudioQuest pursues that ideal with the aid of some high-tech materials and designs. You might not expect a joined cable this thin and lightweight to deliver such great sound. So how does AudioQuest makes it happen? It's all about the details.
Solid Perfect-Surface Copper+ (PSC+) conductors
One of the most important materials that goes into an audio cable is the metal used for its conductors the parts of the cable that actually carry the signal. Big Sur cables feature conductors made from a material AudioQuest calls "Perfect-Surface Copper+." PSC+ starts with ultra-pure copper, formed into solid (not stranded) conductors with an astonishingly smooth surface. The end result: clean, low-distortion signal transfer for transparent sound.
Advanced cable geometry
While many cables use a single path for both the ground and shield, AudioQuest uses a design they call "double-balanced asymmetrical geometry." This design separates the ground and shield paths for clean, quiet performance.
Cold-welded "Purple Copper" connectors
Big Sur's connectors are cold-welded, rather than soldered, which eliminates a common source of distortion found in many audio cables. They're made from high-purity, gold-plated "Purple Copper," which outperforms more common connector materials where it counts in the listening room.
Fantastic cable. I went from optical back to this analog cable for a more natural sound.

AudioQuest Big Sur Reviews
Average Customer Review(s):
Thanks for submitting your review
Big Sur Series Stereo RCA Cable: The AudioQuest Big Sur stereo RCA cable is terminated by a gold-plated male stereo RCA connectors on each end. The AudioQuest Big Sur stereo RCA cable is available in the following lengths.
- 0.6 meter (2')
- 1 meter (3' 4")
- 2 meter (6' 7")
- 3 meter (10')
- 5 meter (16' 5")
Solid Perfect-Surface Copper+ Conductors (PSC+): Perfect-Surface Copper+ has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire's surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor. PSC+ is manufactured by applying the same exceptional technology to an ultra-pure copper. The resulting sound quality is even more focused and simply less in the way. All of Big Sur's conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the greatest source of distortion, often causing a somewhat dirty, harsh sound. Solid conductors are fundamental toward achieving Big Sur's very clean sound.
Foamed-Polyethylene Insulation: Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. Big Sur uses air-filled Foamed-Polyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials.
Metal-Layer Noise-Dissipation System (NDS): 100% shield coverage is easy; preventing captured RF Interference from modulating the equipment's ground reference requires AQ's Noise-Dissipation System. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment's ground plane.
Double-Balanced Asymmetrical Geometry: Purposely designed for single-ended applications, Double-Balanced Asymmetrical Geometry offers a relatively lower impedance on the ground for a richer, and more dynamic experience. While many single-ended cable designs use a single path for both the ground and the shield, Double-Balanced designs separate the two for cleaner, quieter performance.
Cold-Welded, Gold-Plated Pure "Purple-Copper" Plugs: This plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion. Purple-Copper offers a cleaner, clearer sound than the nickel-plated or OFHC metals commonly found in competing manufacturers' plugs.
Directional: Arrows on the connectors indicate the preferred signal path from the source component to the input.

Why did you buy this?
Upgraded my phono pre-amp and decided to upgrade the cables as well. [ William Keith May 07, 2017 ]
After doing a little research, it seems this cable should maximize good sound delivery at reasonable cost. [ Craig Apr 17, 2017 ]
I have old cords and wanted to upgrade. After reading the description, I decided this would be the best connection. [ Paula Apr 04, 2016 ]
Had Augiuquest G Snake Rca's from my Oppo 105D, decided I wanted to upgrade to something higher up the line [ ANDREW Apr 04, 2017 ]
Highest rated RCA cable for this pricepoint. Really wanted the next series, but that wasnt in stock [ Jeremy Jan 14, 2017 ]
Need and AudioQuest quality! [ J. PATRICK Dec 21, 2016 ]
Bought the Audioquest Evergreens, which are fantastic. Figured I would now get their top of the line cables (Big Sur) since I am now a BIG BELIEVER that cable upgrades are EXTREMELY important, especially when using them for connecting a turntable to an amp. These cables are amazing. If you have a nice turntable system, don't skimp out on the cables, they are just as important as the cartridge you choose. Seriously. [ ERIC E Feb 17, 2017 ]
Need and AudioQuest quality! [ J. PATRICK Dec 21, 2016 ]
High quality interconnect. Good shielding, low noise. [ PAUL Jul 19, 2016 ]
I like audio quest and realized the ones I ordered yesterday were too short. [ Chris Mar 29, 2016 ]
Picked on Kevin's recommendation [ Gary Dec 19, 2015 ]
Great reviews [ Philip Jun 08, 2017 ]

Both of the given answers were correct for the situation stated. [ Bernadette Dec 01, 2016 ]
From source to component, i.e. from tv to stereo receiver. [ Anthony Nov 30, 2016 ]
Hi Bernadette! Good question. Think of those arrows as indicating the direction of the audio signal. As an example, in connecting a CD player to a prep, connect the cables so that the arrows point toward the preamp. Enjoy your system! -Jim [ James R. Nov 28, 2016 ]
