For specific types of applications, a shielded version of the Cheetah cable comes in very handy. This especially applies to DAC’s, pre-amplifiers, transports, CD-players, but also to power amplifier units, which tend to be on the dark side.
The screened, shielded versions of these Cheetah cables tend to zoom-in on the upper mid-range of the audio spectrum, providing for a richer level of perceptible details.
Analytical systems may not necessarily want to use this versions, as too much analytics may lead to the perception, that the sound is overloaded with information, too much detail, and hence tiring.
But some of the dark sounding systems will be very happy to take such a power cable on-board and as an integral part of the system.
Current executions are based on the FI-28(G) and FI-38(G) plugs, and have a black protective sheaf as the outer layer. As for the shielding material, I use a high quality American braid type of shield. It is either pure copper, or (more recently) tinned copper. The braid is very dense and provides good covering.
Below – are some early versions, prototypes, of the screened, shielded versions of the Cheetah cables.
The historical versions of cables used a variety of aluminum based connectors. Although they “had the looks”, but unfortunately they did not “have the sound” within them. They are now discontinued.
