STIS Terminals
Shunyata Research developed an interchangeable terminal system that allows the customer to change from different size spades to bananas without the inconvenience and expense of sending the cable in for re-termination. The design of connectors ensures that there is NO loss of performance compared to a conventional terminal.


ΞTRON® COBRA speaker cable features the ΞTRON® circuit technology at its most reasonable entry point and delivers a performance far beyond its modest price. They should be considered for any system that aspires to reference levels of performance without having the burden of VIP priced cable systems.

When deciding to evaluate speaker cables or interconnects — first, consider that Shunyata speaker cables such as the PYTHON will make the most profound difference for the most reasonable cost. When deciding to try one or the other, they should be considered first, or preferably, along with the matching technology interconnects for best effect.

Whether building a no-compromise sound system or merely trying to get the most out of a more reasonable system budget, the COBRA speaker cable offers more than a glimpse into the benefits that a measurably superior cable technology can offer.
