The performance of any amplifier is ultimately limited by the dynamic
abilities of its power supply, and for this reason Cambridge amplifiers
feature generously over specified power transformers, discrete diode
rectification and selected high speed reservoir capacitors. Power
regulation is also used wherever possible and our transformers are
custom designed, low flux type, allowing for the instantaneous clean
delivery of current whenever it is needed.
Particular attention has also been paid to the quality of the passive
components where close tolerance metal film resistors and audio grade
signal coupling capacitors are used throughout. Critical line level circuits
are also protected from electrical noise by our custom designed gold
plated shielding cans.
Some Cambridge Audio amplifiers also incorporate tone controls, which
may be switched out of circuit in 'direct' mode for the shortest and
therefore purest signal path. Other features include increased
protection against accidental short circuits or sudden overload and dual
sets of high current loudspeaker terminals for easy bi-wiring.
To get the absolute best from this equipment we would encourage you
to use only high quality source components. Of course we particularly
recommend tuners and digital equipment from the Cambridge Audio
range, all of which have been designed to the same exacting standards
as our amplifiers. Many types of loudspeakers were used in the
development of these amplifiers to ensure maximum compatibility with
a wide variety of designs.
Interconnects and speaker cables are also something that shouldn't be
overlooked. Please do not compromise your system's performance by
using poor quality cables to connect source components to your
amplifier or the amplifiers output to your loudspeakers. A system is only
as good as its weakest link. For this reason we do not include cheap
"freebie" cables with any of our products. Your dealer can supply good
quality Cambridge Audio interconnects and Mordaunt-Short/Gale
loudspeaker cables that will make a noticeable improvement to the
sound quality of your system.
Now w
we iinvite yyou tto ssit bback, rrelax aand eenjoy!
