With the advent of DVD, digital satellite and high performance DACs, more digital sound sources are in more homes than ever before. While the choice of signal transfer - optical or coaxial - is dictated by your components, the delicacy of the digital signal is not. The slightest imperfection in cable construction can mean dropped data, signal loss and overall poor performance. Though the Toslink connection is typically not as sturdy as its coaxial counter part, the absence of possible electrical grounding noise makes Toslink the choice for many audiophiles and discriminating home theatre buffs. Unfortunately, most Toslink cables offer meager construction and cheap materials, resulting in poor transmission and data loss.
