QED Performance Audio RCA Interconnect 1.5m
Most people don't spend their evenings comparing capacitance figures. They press play. But if you've invested in a streamer, CD player, DAC or turntable, the cable linking it to your amplifier has one important job: carry the signal accurately from one component to the next. Performance Audio is designed to do exactly that.
Built around QED's proven Solid Complementary Conductor™ Technology, it uses two electrically isolated oxygen-free copper conductors of different diameters to help preserve signal timing and integrity. Combined with advanced shielding and protection against modern household interference, it's engineered to help your system deliver more of the music and less of everything else.
Whether you're building your first serious hi-fi, replacing the interconnect that came in the box, or standardising a growing system, Performance Audio gives you the confidence that you've got this connection right.
Features
- Solid Complementary Conductor™ Technology for improved signal timing
- Ferrite Insulation Technology™ helps protect against RF and digital interference
- Dual electrostatic shielding for improved noise rejection
- 99.999% oxygen-free copper conductors
- Low-loss foamed polyethylene dielectric
- Ultra-flexible TPE jacket for easier routing and reduced handling noise
- Gold-plated QED connectors for long-term reliability

About the QED QE7704
From our tech experts at CEN
The QED Performance QE7704 is a 1.5m stereo RCA (phono) analogue interconnect. It shares the range's Solid Complementary Conductors, ferrite impregnated absorption layer, foamed polyethylene dielectric and gold-plated QED phono plugs, so you get the same build as the shorter and longer versions at a mid-length.
Who it suits
Pick 1.5m when your source and amplifier sit on different shelves or side by side rather than stacked, for example a turntable phono stage on a sideboard feeding an amplifier below. Use the 0.75m QE7701 for stacked components, or the 3m QE7707 for equipment across a room.
Our tech experts advise
Route the cable along the back of the furniture before measuring, then add a little slack. Push the phono plugs fully home so the gold-plated contacts seat properly. Keep analogue interconnects clear of mains leads and power supplies to keep the noise floor low. See the full range in our QED collection.
