Galileo SX IFT Bi-Wire Speaker Leads
Galileo SX Speaker Cables and IFT Jumpers (Integrated Frequency Transmission) are the result of over 25 years of continual technological advancement, SR's absolute highest performing speaker cables to date. Hand made from Pure Mono Crystal Silver and Graphene in an Air Dielectric each pair takes two days to complete by hand in SR's California factory. State-of-the-art systems exhibit new levels of refinement, dynamics and holography.
Standard length are 18 or 30 inches. Sold in sets of four.
A Better Way to Bi-Wire
When bi-wiring was introduced in the late 1970s amplifiers and speakers benefited due to the relatively modest performance of the speakers and cables of the day. Electronics, speakers, and cables were simply not as advanced as they are today. In fact speaker cables were little more than unshielded 16 gauge lamp cord made from cheap copper with poor dielectrics so doubling up on zip wire was better than nothing. Unfortunately as electronics and speakers advanced over the intervening years most speaker cable designs have not kept pace where bi-wire terminations are concerned. For today’s high end speakers to perform their best it’s absolutely critical they be fed a phase correct signal where all frequencies are in perfect phase alignment across the frequency spectrum.
Low level information relating to spacial queues, holography, image placement, low frequency impact and control as well as high frequency extension without brightness are all aspects of a phase correct signal reaching your speakers. We discovered nearly 25 years ago that it’s difficult enough to get one cable in perfect phase alignment across the entire frequency spectrum, much less to get two cables running in parallel while feeding the very different loads of high frequency and low frequency binding posts on a bi-wire speaker. When signal is split between higher and lower frequencies in separate cable runs phase distortion is inevitable. IFT (Integrated Frequency Termination) provides speed, PRAT (Pace, Rhythm and Timing) and high frequency extension in perfect alignment with low frequencies better than any bi-wire cable geometry can. This is because the full spectrum of frequencies and phase information is present in the cable’s entirety, and not split into separate runs which changes the signal’s phase alignment when frequencies are segregated into separated cable runs.
Disadvantages of The Traditional Bi-Wire TerminationWhen you bi-wire your loudspeakers, the input of the high and the low pass filters are fed with different input signals. This difference is a result of the high and low frequencies being forced to travel different paths, perhaps through different types of cables, but under all circumstances through cables that have seen different loads. A tweeter with a high pass filter has a completely different impedance response compared to a woofer with a low pass filter!
The drivers do not integrate when their filter halves (crossovers) are fed with unequal signals. The result is the generation of phase error that effects the sound and transfer of phase information to the different drivers in a speaker. This phase error occurs because there will be non-linearity in the low and high-frequency paths. What does this sound like? Well, usually, just as you would expect from physics, it appears as a change in the reproduction of space and sound staging. The impression after a week or month is that all recordings sound very much alike.
