MATCHING: It is important to use as close as possible an impedance
match between the amplifier and speaker for optimum transfer of power to
the speaker with minimum distortion. In the case of speaker systems with
significant variations in impedance throughout the frequency spectrum,
such as most electrostatic types, determine the best impedance match
empirically for best overall sonic results.
It is important sonically that your entire system be connected so that the
audio signal arriving at the speakers has correct, or "absolute" polarity (i.e.,
non-inverted). Connect the black or "-" speaker terminal to the wire that
connects to the "0" terminal on the VSi75. Connect the red or"+" speaker
terminal to the wire that connects to the "4" or "8" terminal on the VSi75,
and tighten the speaker terminals securely to ensure best sonic results.
About cables:
Use the best available speaker wires and interconnects. Audio Research
cannot emphasize this enough. As better components and systems are
developed, it becomes increasingly important to avoid the limitations of
inferior system interconnections.
Connect the VSi75 input to the source components using only the highest
grade of audio interconnect cables. To avoid sonic degradation use the
shortest practical length of cables.
