Which Amplifiers do you recommend?
We do not recommend any specific Brands or Models.
However, we can give a few hints on what to look for when selecting your Amplifier/Receiver. Amplifier requirement figures (Watts) are intended only as a guide. As a general rule buy the most powerful amplifier that you can afford within the specified range and use it with great care. It is easier to damage the loudspeaker with a small amplifier driven into distortion using too much volume with bass and treble boost, than with a large amplifier which has plenty of power in reserve. If in doubt, ask your dealer.
What speaker cable should I use?
Our loudspeakers use carefully graded OFC internal wiring and high quality components. The cable between the amplifier and the inputs on your speakers can be a potential limitation in the system. As a general rule, any high quality multi strand or solid conductor will give good results. Speaker cable can be a very personal choice, for best results avoid very thin cables or "bell wire" as they can strangle the signals that your amplifier is sending to your speakers.
There are many good brands of speaker cable on the market.
Refer to Hi-fi magazine tests and dealer recommendations before you decide on the best cable for your system and budget. A suggested budget for cable is 5% of the total cost of your speakers per metre of cable used.
What is Bi-Wiring ?
Bi-Wiring is the use of two pairs of cables between each amplifier channel and the associated loudspeaker. The crossover in a "Bi-Wireable" speaker has two separate earth and or signal paths. By keeping these paths separate all the way back to the amplifier retrieval of fine detail can be improved.
Simply remove the links connecting both positive and negative binding posts together, and run two identical lengths of cable to each speaker from the amplifier output terminals. Special "Bi-Wire" cable is available for a tidier installation.
What Is Bi-Amping?
Bi-Amping is similar in principle to Bi-Wiring but uses a separate amplifier for each set of terminals. This can give even greater benefits than Bi-Wiring as the smearing of the delicate higher frequency information due to masking from the bass information can be significantly reduced. It is important that the amplifiers used are of the same type, or have matched gains.
Speakers that can be "Bi-Wired" can generally be "Bi-Amped" as the crossover is essentially two or more separate circuits isolated from one another (when the links are removed).
