Syncro is not a mains conditioner or filter in the accepted sense. It can be used on its own to power a single hi-fi component, and will bring significant improvements if used in this way.

IsoTek EVO3 Syncro Audiophile Grade Power Cable 2m

 

In simple terms, Syncro is IsoTek’s most advanced mains cable – but it’s also so much more. The cable incorporates innovative electronics, housed in an anti-resonant aluminium case positioned part way down its length. This unique circuitry is designed to synchronise the mains supply in order to promote a perfectly symmetrical sine wave, delivering significant sonic improvements when used with any hi-fi separates system.

Syncro is not a mains conditioner or filter in the accepted sense. It can be used on its own to power a single hi-fi component, and will bring significant improvements if used in this way. However, it is primarily designed as a ‘pre-filter’ device – for best results, plug the Syncro into a wall socket and use it to power an IsoTek mains conditioning unit. Thus, Syncro takes the mains electricity supply and realigns its waveform, prior to filtration of contaminants (RFI/EMI etc.) by the conditioning unit, which then feeds each hi-fi component – thus improving the performance of every link in the audio chain.

The cable itself is identical to IsoTek’s top-of-the-line Extreme power cable. It features heavy-gauge, triple-screened, 20Amp oxygen-free copper conductors suitable for high-current demands, coupled to top-quality connectors at either end. Both the mains plug and the IEC connector are precision machined from high-purity copper, heavily plated in 24ct gold, deep cryogenically treated and then demagnetised. The main bodies are made of injection-moulded polycarbonate, for ease of handling, durability and long-term reliability, while the IEC plug’s precision injection-moulded front assembly ensures precise mating with power sockets.

 

How Does Syncro Improve Audio Performance?

As we fill our homes with an ever-increasing number of electrical devices, we further degrade the mains supply, interfering with its quality and consistency. Audio equipment uses electricity to generate signals, amplified by more electricity to drive a pair of loudspeakers; the quality of the electricity that feeds an audio system has a direct impact on the resulting quality of sound.

IsoTek’s extensive range of mains conditioning components improves the quality of the mains supply significantly, filtering out contaminants like RFI and EMI, and ensuring each component in the audio chain receives pure and consistent power in line with its specific requirements. However, there is a further issue with the electricity supply in our homes that has existed for years, without a truly effective commercial solution. The problem in question is sometimes referred to as ‘DC on the mains’. In terms of audio equipment, it is often signified by a buzzing sound emitted by a transformer in a power amplifier. Of course, this buzz is extremely distracting to the listener, and hardly in keeping with the concept of high-resolution audio. In addition, the mechanical vibration within the power transformer, created by core saturation, results in microphony in the internal components, leading to further degradation of sound quality.

These issues have nothing to do with the quality of the audio equipment used. In fact, some of the best amps available are the most seriously affected. The problem is a symptom of the poor state of mains electricity available in most homes, affecting not only amplifiers but source components, too.

Most of the DC-related issues suffered by audio systems are brought into being by the electrical devices we own, directly ‘rectifying’ the mains from AC to DC (where a diode is used in series to allow either the positive or negative cycle of the mains sine wave to pass). The use of switch-mode power supplies exacerbates the problem, introducing measurable mains distortion. These devices create a lack of symmetry in the mains sine wave where it is displaced from the zero voltage line, leading to the aforementioned hum that’s often noticeable from power amplifiers, as the DC voltage saturates the core of the transformers with DC current. This, in turn, generates unwanted mechanical vibration, resulting in audible noise and microphony, and increased power consumption and heat.

To give an example, if a sine wave reaches a peak of 326 Volts in the positive direction, it should also reach 326 volts in the negative direction to have perfect symmetry. This actually describes the reality of a 230 Volt AC wave form; the 230 Volts describes the heating effect of a sign wave whose peak is 326 Volts. If one peak reaches 327 Volts and the other 325 Volts, there is lack of symmetry. Although common sense suggests that such small variations should have no effect, in reality they create serious problems for audio systems; even tiny changes registering no more than a few millivolts create significant operational difficulties for amplifiers.

 

Inadequate remedies of the past…

Historically, IsoTek advocated the use of huge isolating transformers to improve the cleanliness of the electricity supply (the company has since developed more advanced components for use in its power conditioners). A by-product of this technology helped to compensate for DC elements on the mains. However, this merely shifted the problem away from the audio equipment to the isolating transformer itself; audible mechanical hum may have been removed from the transformer in the power amp, but the isolating transformer would hum instead.

Ironically, in order to try to reduce dynamic loss in the amplifier created by the insertion of the isolation transformer, larger and larger devices were needed. However, the bigger the transformer, the louder the mechanical noise; the problem was never truly solved, merely shifted and often made worse.

 

A new solution: IsoTek Syncro…

IsoTek’s research has led to the conclusion that mains electricity should be a pure sine wave of either 50Hz or 60Hz of correct voltage and good symmetry about the zero volt line, in order to power audio equipment with maximum effectiveness. The Syncro is solely concerned with creating zero-volt symmetry, but also forms a vital part of IsoTek’s product range in working towards the ideal state of a pure sine wave.

In designing the Synchro, the challenge for IsoTek was to offer a universal solution to remove the unwanted and damaging DC component from the mains supply, whilst allowing the maximum possible current to pass. IsoTek’s latest engineering solution and DC-blocking technology developed for the Syncro is in many ways superior in performance to a massive 12,000VA isolating transformer, delivering greater dynamic ability. (Incidentally, a 12,000VA isolating transformer is twice the size of IsoTek’s largest historic product.)

 

Syncro’s sonic effect…

As well as removing any audible hum from a power amp, Syncro’s synchronising effect results in greater bass depth, improved timing, a reduction in the noise floor and a more palpable sound overall. Furthermore, these improvements don’t come at the expense of dynamic ability; in fact, in some cases dynamics are considerably improved. This can be explained by the fact that at zero volume, many power amplifiers consume less power in idle. The Syncro helps the amplifier to consume less electricity, freeing up power for dynamic transients. A simple analogy is a car that is free running, as opposed to having the brakes slightly engaged.

 

"When you factor in the way it doesn’t hold back the dynamics of a system and helps raise the game of products like the IsoTek Aquarius in the process, it’s a no-brainer. IsoTek Extreme power cable is damn fine in its own right, but the Syncro can takes things to a new level." "You know that magic audio quality you only get late at night? Syncro helps unlock that sound, whenever you listen." 

HiFi+

"The most obvious aspect of the performance was a major reduction in harness and ‘mush’... A complete lack of low frequency strain... A highly impressive piece of kit."

Pros: Worthwhile sound quality improvement. Cons: Very expensive!
25 Apr 2020
Verified Buyer
I brought the Syncro to connect my Sigmas, as recommended by IsoTek. It replaced a Premier lead supplied with the Sigmas. Mains quality is not that great where we are in north London. The Syncro does improve sound quality - enhancing the overall beneficial effect of the Sigmas. So it is definitely effective, but against that it has to be said - it’s horribly expensive. You’d probably need a fairly high-endish system to feel the Syncro was cost-effective.

Amp no longer sounds like fridge.
20 Apr 2020
Verified Buyer
I bought a pair of these cables for the power conditioners that feed my monoblock power amps. The amps are rather large (2000w) and their transformers would occasionally hum. This was basically tolerable until lockdown happened and everyone was staying in and using electricity! Suddenly the amps were humming all the time unless it was late at night. The Syncro cables have pretty much solved the problem. The amps are now almost silent all the time - no more horrible waves of transformer hum - and the sound is better. It feels like the noise floor has fallen and level of detail has improved. These cables replaced a pair at a similar price point. The sound improvement may have been in part because my power conditioners are also made by Isotek (Titan One). In my cable fettling over the years I've found, unsurprisingly enough, that Isotek conditioners get along well with Isotek cables... People have told me that a degree of transformer hum is normal with very powerful amps, but it seems to me (from a position of great technical ignorance I'm sure) that a piece of sound-reproduction equipment simply should not itself make sound. The Syncro cable makes this happen. Recommended.

Like all IsoTek products, it does exactly what it .....
2 Sep 2015
Verified Buyer
Like all IsoTek products, it does exactly what it claims to do. Very effective in removing transformer hum and buzzing caused by DC on the AC mains. It is a costly product but removing DC from the mains without affecting the quality of the sound makes it a unique product.
