Audiophile Bi-wired adapters

Audiophile question

What should you do when your speaker cable is a single-wire design (terminated with banana plugs, forks, or pins), yet your speakers feature two pairs of binding posts for bi-wiring or bi-amping?

The Challenge

Many modern loudspeakers are built with dual input terminals, allowing the high and low frequencies to be driven separately. But when using single-wire cables, you need a reliable way to connect both pairs of terminals without compromising sound quality.

The most common and, also, affordable approach is to use metal bridging plates as, supplied with many speakers. And, these connect the high and low-frequency terminals, allowing a single cable to drive both sections. While convenient, these plates are rarely made of high-quality materials and often degrade the sound by limiting current flow and adding resistance.

A more refined solution is to use high-quality jumper cables, short wire links fitted with banana plugs or spades. And, these perform far better than standard metal bridges, but still introduce another connection in the signal path, which can subtly affect tonal balance and transparency.

My Living Voice Auditorium R3 loudspeakers feature two pairs of rear-mounted terminals, yet the manufacturer supplies no bridging plates or jumpers. I’ve used jumpers from Sevenrods for years — well-made with silver plugs — and while they were an improvement, I always sensed some loss of transparency and a touch of harshness in the sound. This changed when my colleague from Lithuania, Mr. Paul Goodwin, introduced me to the Perkune Audiophile Bi-Wired Adapters. These innovative adapters are simple, elegant, and sonically transformative.

The Solution

The Audiophile Bi-Wired Adapters convert a single-wire speaker cable into a bi-wire configuration. One end features a socket for your speaker cable’s banana plug, while the opposite end splits into two precision conductors, each terminated with 24K gold-plated banana plugs. This ingenious design allows seamless connection between your amplifier’s single output and your speaker’s dual terminals — all while preserving purity and performance.

Construction & Design

Each adapter is constructed using the same meticulous standards as the Perkune Extreme Series cables. Key features include:  24K gold-plated collars and connectors for flawless signal transfer, Dual-screw compression fittings that eliminate solder joints, maintaining signal integrity. Aluminium foil shielding for superior insulation, reducing unwanted noise and vibration. AirGap dual-isolation technology to protect against external interference and micro-vibration. Also, the use of aluminium foil offers outstanding noise absorption — blocking up to 85% of unwanted interference, while providing excellent resistance to heat and moisture. In short, the adapters transform your setup into a true bi-wired system — quickly, effectively, and without compromise.

Results

Adding components into an audio path can sometimes degrade performance — but the Perkune Audiophile Bi-Wired Adapters do the opposite. Compared with traditional jumpers, they deliver a sound that is cleaner, wider, and more transparent. The bass gains weight and definition, midrange detail becomes clearer, and the overall sound feels more open and lifelike. The improvement isn’t subtle — it’s meaningful and immediately noticeable.

Yes, they cost more than ordinary jumpers (€397 per set), but the performance uplift they bring is easily worth it. Once installed, they become an integral part of your system — a permanent upgrade that enhances every listening session.

Should You Bi-Wire?

Bi-wiring has been debated in the hi-fi world for decades. The concept is simple: use two pairs of cables to separately feed high and low frequencies from your amplifier to your speakers. This reduces impedance interaction and improves the clarity of midrange frequencies. Not everyone hears the same degree of improvement, but many audiophiles find that bi-wiring brings a noticeable enhancement in definition and openness — especially in systems capable of high resolution.

Ultimately, whether you choose to bi-wire or not depends on your system, room acoustics, and listening preferences. But for those who wish to explore the benefits without replacing their existing speaker cables, Perkune Bi-Wired Adapters are the ideal solution.

Conclusion

The Perkune Audiophile Bi-Wired Adapters offer a simple yet remarkably effective way to convert your standard single-wire setup into a true bi-wired system, unlocking the full potential of your loudspeakers. They are beautifully engineered, and, sonically transparent. Built exactly to the same uncompromising standards as all Perkune products, these adapters are a smart investment for serious audiophiles seeking greater realism, dynamic range, and musical enjoyment.
