XT25’s design is informed by the results of our exhaustive research into loudspeaker cable design which was begun in 1995 and detailed in the recently updated Genesis Report. These design principles to which we have adhered ever since resulted in the development of Supremus speaker cable – the ultimate expression of sound through science without compromise. Each QED cable in the range is based on this unique design and although their design may be variously influenced by price, size or ease of use each retains the basic original features of the flag ship model. This gives even the base model cables a sonic advantage over their similarly priced competitors. XT25 for example was developed as a first upgrade cable for all speaker types whether they be floor-standing or book-shelf stereo or home theatre and so was deliberately designed to be small enough for use in this demanding price sensitive environment.
