USING 4 OR 8 OHM IMPEDANCE TAPS
Our amplifier has multiple impedance taps: try the 4 ohm taps and 8 ohm taps to see which sound better.
They will sound different. It does not matter whether your speaker is specified with 4 or 8 ohms
impedance; the impedance curve is never flat over the whole frequency range but normally varies
between 3 and 10 ohms, with the exception of short-time peaks. Even a classical 4 ohm speaker may
sound significantly better when connected with the 8 ohm tap “against” the technical specification of
the speaker – and vice versa. There is no danger of damaging your amplifier or the speakers by using
either set of taps.
GENERAL REMARKS ABOUT CABLES & MAINS CIRCUITS
There is no one best cable to use with our equipment, and there is also no way for us to accurately
predict what cables will make your equipment sound best.
Research has demonstrated that the cables must be considered an integral part of the music system.
Each brand and model and category of cable has its own sonic characteristics and contributes to the
overall presentation of the music as much as any active component. Our amplifiers/preamplifiers/CD-
Players/speakers can easily pass the amount of information required to hear these differences between
cables. The best cables for your system are your personal taste, the characteristics of your listening room,
and the associated equipment. The only person familiar enough with your taste and room characteristics
to assist you in selecting cables is someone from your local dealer who has visited your room and sat
through listening sessions with you. No one else can adequately evaluate two of the three factors (taste
and room). If you wait to select the cables until the other components in the system are set, you can fine-
tune the system with your cable choice. As you evaluate different cables in your system please
remember that the dielectric in most quality cables takes several hours to fully form. These cables may
not reach their full potential or exhibit their true sonic characteristics until they have been in the system for
a week or more. It is important to keep the speaker cables as short as possible. In repeated trials, short
runs of inexpensive to moderately priced cable consistently outperformed long runs of the same cable as
well as much more expensive cables. If you must place your speakers at a long distance from your
electronics, you should consider positioning the amplifier between the speakers and using long
interconnect cables with short speaker cables. With comparable lengths and quality long interconnect
cables seem to influence the sound of a system less than long speaker cables. An additional advantage
is that a given length of interconnect cable will usually cost less than the same length of speaker cable,
for bi-wiring in particular An amplifier placed between the speakers can easily be concealed by a plant
or placed into a decorative piece of furniture.
Interconnect Cables
Interconnect plugs and sockets should be kept clean and free from corrosion. The easiest way to clean
them is to switch off the equipment, pull the plugs out of their sockets, and push them back in again.
Contact cleaners and “enhancers” should not be used as the film they deposit may degrade the sound.
Mains Circuits
A hi-fi system usually shares a mains circuit with other household equipment some of which can cause
distortion of the mains waveform. This distortion can in turn lead to mechanical hum from mains
transformers. The Ayon transformers are large in size, making them relatively sensitive to such distortion,
and it may be necessary to take account of transformer hum when siting your equipment. Transformer
hum is not transmitted through the speakers and has no effect on the performance of the system;
however, a separate mains circuit may reduce it. Such a circuit (ideally with a 30 to 50 Amp rating) will
also generally improve system performance. Advice on the installation of a separate mains circuit should
be sought from a qualified electrician.
