H7-LITZ INTERCONNECT CABLES.
||H7 Litz Balanced Interconnect Cable 1.5m with DH-Labs XLR Plugs
was the first inductor design company to introduce inductors made with Hepta-Litz
conductors. We pushed it further by implementing Hepta-Litz
in the manufacturing of audio cables. The problem is that music is far from being dc and other non linear losses arise from ac frequency that can increase the ac resistance many times the dc value, even at audio frequency. Let us consider some of those losses.
As the frequency increase, additional power losses occur in the audio cables due to eddy currents in the conductors and by the magnetic fields within the audio cables. In the design of audio cables both skin effect and proximity effect need to be considered. Both effects depend on the ratio of the conductors’ diameter to the penetration depth of the electrons.
▸ Skin Effect
Skin effect is the tendency for the alternating current to flow near the surface of the conductor as the frequency increase. It is due to eddy currents in the conductor that arise from the alternating magnetic field associated with the current in the conductor itself.
▸ Proximity Effect
Proximity effect is the tendency for the alternating current to flow and return along the length of each conductor within the winding in a way that opposes the magnetic field as the frequency increase. It is due to the eddy currents in the conductor that arise from the alternating magnetic field interaction of the other conductors within the audio cable.
▸ H7 Litz Conductor
To reduce those losses, we have to replace the solid conductor or multi strand conductor with a number of separately insulated smaller conductors twisted together, the Litz conductor. The reduction of the conductors’ diameter along with the increase in the number of twisted insulated conductors that tends to occupy all possible positions in the cross section of the resulting conductor are very effective in reducing both effects. The smaller insulated conductor makes the current to divide uniformly between them thus reducing the skin effect losses. The twist of the smaller insulated conductor cancels the EMF's induced by the traverse magnetic field thus reducing the proximity effect losses.
This design idea, Hepta-Litz H7
that consists of seven twisted insulated conductors, results in equalizing the ac resistance to dc resistance ratios in the usable audio frequency band that is establishing new standards in audio cable quality. The Hepta-Litz H7 Interconnect Cables are a clean slate design, based on proven state-of-the-art technology that we have successfully transferred and merged to achieve superiority on all fronts. They will dramatically improve the performance of any audio equipment by linearizing the interconnect cable reactance curve to the ideal reactance.
In conclusion this is the Interconnect Cable you need if you wish to listen to your audio system not to your cables…
