AudioQuest Big Sur Interconnect Cable - 1.0 Meter - RCA to RCA - Pair

Big Sur Tops the Foamed-Polyethylene Bridges & Falls Cables

AudioQuest's Big Sur is the fourth Bridges & Falls cable and the best of the four that Stereophile recommends together. It is one cable with a single conductor body that splits at each end into the left and right RCA plugs, carrying both channels; it is not sold as a single-RCA cable. It uses solid Perfect-Surface Copper+ in a Brown/Black Braid jacket, and upgrades the plugs to gold-plated pure Purple Copper.

Other length & termination options are available. Call us to discuss your needs.

Solid Perfect-Surface Copper+ in Foamed Insulation

The wires are solid Perfect-Surface Copper+, which AudioQuest calls PSC+. It is a higher grade of the smooth copper used in Golden Gate. AudioQuest says the skin cuts the distortion that grain boundaries cause. Each wire sits in foamed plastic that is mostly air.

The Gold-Plated Purple Copper Plug, Explained

Big Sur ends in a cold-welded plug. Its body is pure Purple Copper, AudioQuest's high-purity copper, under the gold. The cables below it use gold over a base alloy. A press bonds the plug to the wire without solder, which AudioQuest calls a common source of distortion.

Big Sur uses Direction-Controlled Conductors, with each conductor set to run in one direction. The layout gives the ground path a lower impedance than the signal path. AudioQuest says this makes the sound richer.

What Reviewers Are Saying

Big Sur is listed in Stereophile's Recommended Components. The entry notes that Big Sur "upgrades the other models' gold-plated RCA plugs to gold-plated plugs of pure purple copper."

Moving up the four, the listing says, Stephen Mejias heard improvements in image focus, tone color, drama, and overall clarity and extension. Stereophile calls all four cables attractive, well made, and very flexible.

Who Is This Interconnect Best For?

• You want the best of the affordable four — Big Sur tops the four Stereophile recommends together, so it is a natural stopping point
• You listen for tone color — Stereophile heard richer tone color up the line, so instruments sound like themselves
• Space behind the rack is tight — one slim cable carries both channels, so it bends where a pair will not
• You want a copper plug — the plug body is pure Purple Copper under the gold, so the last inch matches the wire
• Your left and right jacks sit far apart — both channels share one conductor body that splits at each end. For mono amps or a very wide rack, call us and we will help you choose the right cable

How Does It Connect to Your System?

Run Big Sur from a line-level output, a DAC, streamer, CD player or phono stage, to a line-level input on your amplifier or preamp. Keep left to left and right to right. Push each plug straight on until it seats. Pull it off by the barrel, never by the cable.

Then listen.

Measure the Path, Then Add a Little Slack

Measure the route the cable will really take between your components, around shelves and behind the rack. Then add a little slack. As audio legend George Cardas puts it, "A cable that's just long enough usually turns out to be just not long enough."

A Long Run Between Components?

If your amplifier and speakers sit far from your source, we recommend a long interconnect over a long speaker cable. A really long interconnect affects system performance less than a really long speaker cable.

When Is It Time to Upgrade?

An interconnect often stays in a system for years, so it is easy to overlook. Look again when something else changes: a new DAC, streamer or phono stage, or a better amplifier.

Pairs Well With

An interconnect is one link in the chain. It usually joins these categories.

• Integrated Amplifiers — the usual input end
• Digital-to-Analog Converters — DAC output to amplifier
• Music Streamers — streamer output to amplifier
• Speaker Cables — the last link to the speakers
