Loudspeaker cables and signal cables (inter-connects) have a significant
influence on the overall reproduction quality of your sound system, and their
importance should not be under-
the use of high-quality cables and connectors.
Our accessory range includes a series of excellent cables and connectors
whose properties are carefully matched to our speakers and electronic units,
and which harmonise outstandingly well with them.
For difficult and cramped situations the  range also includes special-
length cables and special-purpose connectors (e. g. right-angled versions)
which can be used to solve almost any problem concerning connections and
system location.
The mains power supply provides the energy which your sound system
equipment needs, but it also tends to carry interference from remote devices
such as radio and computer systems.
Our accessory range includes the specially shielded 'POWER THREE' mains
cable and the 'POWER BAR' mains filter distribution board which prevent
electro-magnetic interference from entering your Hi-Fi system. The
reproduction quality of our systems can often be further improved by using
these items.
