Each component can only process the signal that it receives. Improve the quality of the signal transfer and the benefits can be dramatic.
High quality audio & video from today’s sources will be restricted in performance if poor quality cables and connections are used. Any information lost here cannot be recovered later.
For these reasons we would always advise that cables are not just ‘bits of wire needed to make things work’. Quality connections should be viewed as an integral part of any system.
Surprisingly good results can be achieved with even modest systems if care is taken in choosing appropriate mains cables, audio interconnects, digital cables, video and HDMI as these all have a part to play in delivering the final result that you see and hear.
