SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS:
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. For over 30 years AudioQuest has pioneered the use of superior metals; yet even we were surprised by the huge leap in performance made possible with Perfect-Surface Technology. PSC+ simply outperforms all previously available copper metals at any price. 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.

ASYMMETRICAL DOUBLE-BALANCED GEOMETRY: 
Purpose designed for single-ended applications, Asymmetrical Double-Balanced 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 TERMINATIONS: 
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 instead of machinability. Purple Copper offers a cleaner, clearer sound than the nickel-plated or OFHC metals commonly found in competing manufacturers’ plugs.

⭐️⭐️⭐️⭐️⭐️ Perfect for My Suit-Loving 9-Year-Old 🤍👔✨
My 9-year-old is obsessed with suits, and this one was a total win! 😍 The 3-piece set (blazer, vest, and pants) makes him feel so grown-up and confident. The linen material is lightweight and breathable, which is perfect for warm weather ☀️ — and it doesn’t wrinkle easily, which I appreciate as a parent 🙌. He loves that he can wear it different ways — full suit, just vest and pants, or blazer and pants. 👌 The fit looks sharp, and the adjustable waist is super helpful. Perfect for weddings, school events, church, or any time he wants to dress to impress. 💙 Definitely a favorite in our house! 🎉

Adorable special occasion suit for boys
Size: 5, Color: Light Blue, Size: 5, Color: Light Blue
I ordered this 3-piece suit for my son and even though it’s currently a little too big for him, I couldn’t resist keeping it because it’s absolutely adorable! The quality really impressed me right out of the package. The fabric feels lightweight and breathable, which will be perfect for warmer weather, and it has a nice polished look without feeling stiff. The set comes with a blazer, vest, and pants, and each piece is very well made. I love the little details like the lapel on the jacket, the adjustable strap on the vest, and the adjustable waist on the pants, which will definitely help as he grows. It looks like a much more expensive suit than it actually is. Even though my son will have to grow into it, I’m already excited for him to wear it. I’m thinking it will be perfect for Easter next year or any special occasion. It’s such a cute outfit, and I love that the pieces can be mixed and matched for different looks. Overall, I’m really happy with this purchase and can’t wait to see him wearing it! The blue color goes well for any occasion and I may have to order my husband a suit in matching shade of blue so they can be twins. The size looks accurate for boys 5T. I took a picture to show the pants next to a pair of unwashed Oshkosh B’Gosh brand straight leg 5T boys denim jeans.
