Whatever level of quality you are looking for in an interconnect you will find a cable in the QED interconnect range to meet your needs.
QED have always been a strong contender if you were looking for an entry level interconect at an affordable price. But they were never really a strong player of you were looking for a high-end audiophile interconnect. However, with the introduction of the new Signature range QED have established themselves as serious player in the high sector. The new Signature range has received very favourable reviews.
QED's range has interconnect cables in each of three quality levels: Performance, Reference and Signature.
