inductors use oxygen-free, high purity
copper (OFHC) wound on bobbin cores to
improve saturation current limits, reduce
d.c. resistance and minimise stray magnetic
field leakage.The capacitors are
manufactured with an over-size
polypropylene dielectric and are rated at
250V DC to guarantee uncompressed
power output.The resistors are high power
devices offering extremely high peak
voltage operation without compression. All
component connections are hard-wired as
opposed to being printed circuit board
tracks to maintain optimum transfer of
music signals.
OFHC loudspeaker connection
terminals
The use of proprietary OFHC gold
plated binding posts achieves a clear sonic
improvement compared to the typically
used alternatives employing high copper
content alloys. Furthermore, nickel plating
has not been used between the OFHC
foundation and the gold finish as it added
‘grain’ to the sound.Whilst this will lead,
in the long term, to some dis-colouration of
the binding post due to the copper atoms
partially diffusing into the anti-corrosion
gold layer, the customary nickel plate
interlayer is well known to affect sound
quality and was eliminated.
single input connection
After extensive research into the sound
quality of the F1 AvantGarde loudspeaker, it
was discovered that the potential benefits of
multi-wired terminals for loudspeaker
cable connection were outweighed by the
losses incurred in their implementation,
e.g. additional contact interfaces and
electrical connection straps. In addition, it
has been found that even with the finest top
grade power amplifiers, single input
terminals improved perceived dynamics and
musical expression.The results of this
research have been applied to the full range
of Aluminium Technology loudspeakers.
