Is it true that this cable improves the sound quality of hi-fi systems?
Black Rhodium Stream Power Cable
A POWER CABLE OPTIMISED FOR MUSIC BY ITS LENGTH
'Stream is a new audio mains power cable designed to achieve high sound quality by using the latest Black Rhodium high end cable technology.'
Stream is optimised for the best sound quality by its length. During the design period, Black Rhodium tested one of its most popular power cables in several different lengths. Listening tests showed consistently that the best sound quality was obtain from cables cut to a length of 1.65m (wire length 1.68m after untwisting). This aligns very closely with the quarter wavelength of the 50 Hz mains frequency of 1.7m. Further tests showed that cables in multiples of 1.7m sounded superior to lengths than those of slightly above or below. However the longer cables in multiples of 1.7m did not match the sound quality of 1.65m.
Stream is hand built at the Black Rhodium factory in Derby to advanced design techniques developed by Black Rhodium for use in its most expensive products.
LOW LOSS SILICONE RUBBER INSULATION REDUCES TIME SMEARED DISTORTION.
The wires in Stream are insulated in silicone rubber because its low dielectric loss ensures extremely low distortion due to dielectric absorption effects in which sound energy is absorbed in the insulation and released at a later interval of time to create highly audible time-smearing distortion.
ULTRA LOW TRANSIENT PHASE DISTORTION THROUGH INNOVATIVE DESIGN.
Stream gives a very clear diction of a singer's voice and separates musical instruments superbly through a dramatic reduction of 'Transient Phase Distortion'. 'Transient Phase Distortion' is reduced by using thicker insulation than is usual in speaker cables, increasing the distance between conductors and thereby reducing the magnetic field seen in each conductor wire as a result of the magnetic field created by the current in the other conductor wire.
The manufacturer’s website stated:
TITAN is a superb cable for upgrading hi-fi music systems. Even if you already have good mains cables, Titan will give you further improvement in all areas of performance.
Titan mains cables have three separate layers of screening to protect the mains voltages it carries from all external noise.
