Interconnects, Speaker & Headphone Cables for Hi-Fi - including digital

We believe our range of audio cables give a far better performance with our audio equipment than any other cables - and so do the vast majority of our customers.

It stands to reason that they will, because we have all our products on hand to test and audition them with.

Interconnect, headphone or speaker cable; they are carefully crafted to perfectly match the input and output characteristics of our products, and that of the equipment they are so often partnered with.

Take the guesswork out of choosing audio cables by insisting on interconnects, headphone cables and speaker cables from the Graham Slee audio cables range.

AgSat90 Audio Interconnect

Interconnect | AgSat90

By adding silver "reinforcement" to the CuSat50 you get the good points silver brings to an interconnect, without all the silver side-efects. That's the AgSat90!

Silver is the most conductive metal above copper. However, commercially produced recordings are balanced to "sound right" with regular cables. The usual outcome when using all-silver interconnects is severe brightness and an unhappy listener!

But some systems are simply crying out for a little extra sparkle — the answer is right here in the AgSat90 - added sparkle without the hassle.

Lautus Audio Interconnect

Interconnect | Lautus

So you still think you could be getting a more dynamic feel – a larger sound stage – deeper bass? But you're all spent up having bought all our great audio products. What do you do?

Firstly let us assure you our equipment isn't standing in your way, but the proliferation of high frequencies way beyond the audio spectrum most likely is!

Think about it — there are more broadcasts, more wi-fi, more mobile phones than ever in history! They're all electro-magnetically incompatible with your listening pleasure!

Enter the Lautus! An audio interconnect designed to be the antidote for the modern age and bring your music back to life.

Universal DIN Breakout Cable

DIN Breakout Cable

DIN sockets feature on a number of hi-fi integrated amplifiers and preamps but it makes it difficult for users of such equipment to use different interconnect cables that only come with RCA/phono plugs.

Equipment made by Naim, Bang & Olufsen, Quad, Meridian and Audiolab can feature 180 degree 5 pin DIN sockets for input and output connections. Often when shopping for the right cable confusion arises because things like tape outputs cross over to different pins on tape inputs and the like.

This DIN breakout cable solves the problem of connecting 5 pin DIN equipment with RCA phono jack equipment.

All connectors have hard gold plated contacts. Click image for enlargement.

Spatia Speaker Cable

Spatia Speaker Cable

Low memory makes the Spatia the most spatial speaker cable you'll ever need. Music consists of rapid changes in asymmetrical waveforms which due to capacitance are remembered by cables and confuse the spatiality, upsetting the sound stage and often altering tonality.

What you need to guarantee the most spatial and tonally correct musical performance from your speakers are the Spatia low memory speaker cables

Spatia Links

OK, you've heard all of the tall stories hi-fi can offer and then some.

Therefore you'll not believe that replacing the metal links on bi-wirable speakers with our Spatia Links could make any difference?

And you probably will think we made this customer appraisal up:

"Fitting the Spatia Links however, has dramatically improved the sound, with the bass coming through, providing a deeper and richer sound throughout. I am playing Led Zeppelin's Physical Graffiti (a fave from my teenage years) and I cannot believe the change in how it now sounds."

So we're not saying any more about them.

Cable related terms and their meanings

Balanced: the signal is split by the output of a device into two phases - one part of the alternating current music waveform going positive whilst the other is going negative. The signals are said to be differential and are combined by a differential input stage at the receiving device. A pair of conductors for each phase is required and these conductors are twisted such that any noise/interference they pick up is common to both of them (common mode). The differential receiving input "looks" for the difference signal and thus common mode noise/interference is rejected. The amount of rejection of the receiving device, or the accuracy of balance from the source device which can compromise the receiving devices rejection, can vary from one product to another, and the addition of an overall shield to the cable to surround the pair of conductors, which is connected to each devices ground, assists with noise/interference rejection. Balanced interconnection is only of real benefit when connecting pieces of equipment some distance from one another.

Balun: a device to convert single-ended to balanced, or balanced to single-ended.

Break-out cable: a cable or number of cables coming out or entering a small connector to facilitate the use of a number of cables, or larger cables, having different connectors, to or from it.

Coax: short for coaxial — a cable having a central conductor surrounded by a shield spaced away from the central conductor by an equal amount - in other words, concentric.

DIN: Deutsches Institut für Normung (German Institute for Standardization) type connector often used for audio on compact audio equipment. It is a small connector and difficult or impossible to use heavier cables for stereo wiring with. Otherwise very reliable. It's pin out varies by the number of pins and the angles between pins. The one most encountered in audio is the 5-pin 180 degree type where: pin 2 is shield, pin 3 - left in, pin 5 - right in, pin 1 - left out, pin 4 - right out.

EMC: stands for electro-magnetic compatibility — such compatibility is essential to prevent the distribution or redistribution of interference signals often caused by the proliferation of radio frequencies and devices that operate at them.

Ground: the common point of a circuit also known as 0 volts, or zero-volts.

Ground-lift: must only be used on balanced interconnections otherwise the return path of a single-ended cable will cut the signal - or the return path will be through the mains earths on equipment so earthed, which would yield undesirable sound quality. Lifting the ground means disconnecting the shield, and is used to remove "hum" or "buzz" when both balanced equipments are directly grounded to mains earth - thus removing a ground loop. Ground lifts can often allow in VHF and UHF interference and other means to a solution would be better.

Ground loop: where the ground connection between equipment is connected both by their respective mains earths as well as the interconnect shield - thus making a loop.

Screen: the protection against noise/interference surrounding the conductor or a number of conductors in a cable. It should be connected to the source or reception equipment common or zero-volt point, and the cable assembly arranges for this. It should be highly conductive to minimise ground differences or potentials between equipment to prevent it adding noise/interference instead of protecting against it. It should also provide effective coverage.

Shield: interchangeable with screen — means the same in most circumstances you'll come across. Shield can also be used to describe cable armour on heavy electrical cables.

Single-ended: conventional input or output where the signal is on one wire and the return path is the ground.

TRS jack: either a stereo or GPO 316 jack socket or plug used for balanced audio connection. In fact, the GPO 316 type TRS jack was used before the XLR for balanced audio connections - often found on old telephone switchboards. T or tip -"positive" phase, R or ring - "negative" phase, S or shaft - shield.

XLR: a connector usually three-pin for balanced audio use, but available in 4 and 5-pin for other uses. Originally the professional equivalent of a 3 pin DIN connector (hence X-shield, L-left, R-right), it is now almost universally used for balanced audio - especially microphone cables. It is also used for signalling between lighting effect units. The XLR connector can be used to interconnect single-ended devices to balanced devices (but only over relatively short distances) — one of the balanced phases - normally the "positive" phase (pin 2) - is used for the signal whilst the unused phase (pin 3) is either left floating (important if it is an output!) or most commonly grounded to pin 1, to ensure the opposite phase of an input is not left floating and able to pick-up noise. The convention for 3-pin XLRs in audio use is "pins" (male) for output and "holes" (female) for input — you will see this is the standard by looking at the connector on the output of a professional microphone.
