BRYSTON SPEAKER CABLES
SPEAKER CABLES
The Amplifier/Speaker interface is a ‘low impedance’
connection. Therefore, in a speaker cable you are looking
for low ‘self inductance’ (because inductance rolls off the top
end) as opposed to ‘low capacitance’ required in the RCA
or XLR analogue interconnect. For speaker cables we use a
stranded 9 gauge linear crystal copper with ‘Heavily Gold
plated’ Spade lugs or Expandable Banana plugs specially
made for Bryston.
IN SUMMARY:
1. The connection should be of similar metals (preferably
gold) and be airtight. If not airtight it will break down
molecularly over time and begin to rectify or produce a
diode effect on the signal.
2. With all the RF floating around today the better
the ‘Shield’ on the interconnect the less
intrusive the RF will be.
3. The connection between
your analogue Source
components (Preamplifier,
CD Player, Tuner, DVD
Player etc.) is a ‘High
Impedance’ connection
and the interface between
your power amplifier and
your speakers is a ‘Low
Impedance’ connection. So,
the requirements are totally
different for optimizing these
interfaces.
4. Digital and Video cables are much more susceptible
to reflection/phase/cancellation problems because of their
short wavelengths relative to cable length.
As you can see from the above, no surprise that people hear
differences in cables when connected to the variety of equipment
in the market today. Given the differences in input and output
impedance’s between transistor and tube gear, the lack of
understanding of the high impedance and low impedance
interfaces, the world of RF, and the digital/video connection
issues no wonder we have these differences of opinion.
RECOMMENDATIONS:
Bryston highly recommends keeping the speaker wires as
short as possible and utilizing XLR balanced lines if available.
Given the choice of long interconnects and short speaker leads
or short interconnects and long speaker leads – choose long
interconnects (preferably Balanced) and short speaker leads.
With digital and video cables finding out the sending and
termination requirements is very important due to the very
short wavelengths relative to cable lengths involved.
