Graham Slee CuSat50 Analogue Interconnect

Graham Slee CuSat50 Analogue Interconnect

Graham Slee Cusat50 analogue interconnects have a very low capacitance, and thus do not load your source components output on it's way to your amplifier - this eliminates the possibility of induced radio frequencies which can cause ringing in the transmitted signal - this makes listening harsh and fatiguing. Shielded from both RFI and EMI, the interconnects are terminated with very high quality phono plugs to enable you to get the best from this highly neutral cable.

Protecting The Signal

The great thing about such a robust and highly conductive shield like the CuSat50's is its thorough protection from interference getting to the signal conductor inside.

The hi-fi fashion over the last decade or so has been to "play around" with interconnects, often not using any shielding at all, but just having two wires - one for signal and one for return - which offers no protection at all. Another trend has been to tightly twist send and return wires, which may work to some extent in balanced audio, but again offers little protection in single-ended connections.

The third trend we know has been to use twin cored shielded cable but only use the two wires for signal and return, leaving the shield unconnected. A shield without any signal return current running in it offers no protection! Then there's a variation on the last which connects the shield to ground at one end only, but that's only partially effective up to some cable-length dependant frequency, after which inteference is free to do its worst.

Low Capacity

The capacitance of the CuSat50 is only 55pf per metre which means it won't attenuate high frequencies even in longer lengths. Most preamps, or any other signal processing equipment outputting analogue audio, have output impedance which guards against instability from capacitive loading.

But that output impedance (ac resistance) can form a low-pass filter with the cable capacitance, filtering the highest frequencies. Tubed equipment has the highest output impedances which limits its ability to drive long cables. Some products have little or no output impedance which can leave them prone to instability from too high a cable capacitance. If you're in any doubt at all and want to ensure the correct operation of your equipment you should make the CuSat50 your number one choice.

Quality Connectors

With sprung split centre-pins and collet twist-locking barrel RCA/phono plugs - with gold plating - the CuSat50 make excellent 360° connections with all RCA/phono jacks. That's simply not the case with some "fashion" hi-fi RCA/phono plugs, especially those single contact plastic plugs some sellers rave about. The CuSat50 makes good and reliable 360° contact - plus - they're easier on you and your equipment by you not having to exert extreme force to push them on or pull them off.

The CuSat50 can also be fitted with XLR and TRS connectors (stereo jack plugs used on balanced audio equipment) again using high quality connectors mainly from the world-renowned Neutrik.

Who is Graham Slee?

Graham Slee is a small, enthusiastic manufacturer of realistically priced, high performance phono stages and headphone amplifiers, designed and built by hand in Yorkshire since 2003. Very positively reviewed by UK and international magazines, demand for these products has been overwhelming as the world's hifi enthusiasts can't believe the performance on offer for the price asked.
