      For many years, the design and performance of loudspeaker cables has been a subject shrouded in mystery. Comparison of cables, it seems, has been limited almost entirely to the vagaries of subjective evaluation. The extravagant and undocumented claims touted in almost all advertisements for cables has led sensible audiophiles to suspect that a substantial amount of snake-oil and buzzard-salve have been the key components of their "high-tech" designs. What has been lacking, but sorely needed, has been a sober approach based upon the application of sound engineering considerations and well known scientific principles.
     
      Now, with the Z6, a cable exists that was designed according to sound engineering and scientific principles. It’s accurately documented performance properties are truly relevant to how the cable interacts with the loudspeaker and the power amplifier - essential to obtaining accurate, unaltered reproduction of the most complex musical transients. It is a cable with a difference that can be measured by credible objective comparisons with other cables, offering the potential for audible improvements in music and movie sountrack reproduction. The Z6 represents a real engineering advance at an affordable price. Compared to other loudspeaker cables selling for much more, the DAL Z6 is truly without peer in every performance category.
     
      For example, most audiophiles are familiar with the need for carefully selecting a low-loss cable with an impedance that matches that of their television sets as a means of reducing picture blurring and ghosting. Unlike other loudspeaker cables, which exhibit impedances that range from 20 to over 100 Ohms, DAL Z6 exhibits an impedance of only 6 Ohms, insuring and excellent match to well-designed loudspeakers with average impedances ranging from 4 to 12 Ohms. As a consequence, Z6 loudspeaker cable eliminates almost all blurring and ringing of complex musical transients that other cables with much higher impedances cannot accurately reproduce.
     
      Further, the extremely linear amplitude and phase response of the DAL Z6 insures perfect reproduction of even the most delicate and detailed nuances found in music, compared to even the most expensive cables which suffer typical losses exceeding 2-3 dB at only 20 kHz.
     
      So forget all the subjective and fanciful claims of the competition, and recognize the distinct and real advantages that sound physics and proven scientific principles used in the design and manufacturing of the Z6 allow. It’s better because it is.
     
      Dunlavy Audio Labs Z6 loudspeaker cable is a Stereophile "Recommended Component."
     
      The DAL Z6 cable’s design is covered under United States patent #5,510,578 (April 23, 1996).
