QED's Reference 40 builds on the multi-award winning audio 40 range of products, available with both XLR and RCA plugs.

Building on the success of the award-winning Performance 40, QED's Performance 40i contains two 99.999% OFC conductors of different diameters to accommodate high-frequency audio components and a foamed polyethylene dielectric. The result is remarkably well-defined sound at a very competitive price.

The revolutionary Reference Audio 40 analogue audio interconnect celebrates 40 years at the forefront of British designed audio cables.
