About this deal

Note that for (e.g. valve) amps and preamps and other devices that draw the maximum current continuously, you cannot (and must not) assume that the capacitance needed can be Lastly, the SupaNova active power cable takes the Nova and adds a cylindrical housing part way down its length. This cylinder contains Active Noise Cancellation II – the latest version of iFi’s proprietary noise-busting tech – in combination with advance-filtering components.

The 1,500µF figure is flexible, and my suggestion is to use a pair of 4,700µF caps in series (2,350µF nominal), which will work well in the majority of systems without any need to mess around with calculations. Excessive capacitance may be as bad as too little, because the charging time is so long that many of the DC 'events' may not last long enough for the caps to charge and remove the DC component. The capacitors need to be able to handle the maximum worst case current. For the sake of the exercise, it is worthwhile to size the caps so that they are capable of handling the full load current - 2A. On this basis, it is better to select a much higher voltage than needed to ensure that the ripple current rating is high enough. Although 16V caps would seem perfectly alright, 63V caps will have a ripple current rating that's more than double that of the low voltage type. The extra size helps to keep the cap cool, improving life expectancy.Offers radical improvement in mains quality, transformer and power supply performance, and therefore sound quality Our Installation Service only includes connecting to existing points and fixings. This does not include installing or moving plumbing, connection points or electrics. Installing new points or moving existing points is the customer’s responsibility we can recommend local tradesmen however this will be at the customer’s expense and we not accept any liability for their work.

With six AC outputs, connect your system to clean, DC-free power for a significant performance upgrade. We do provide installation options for built-in appliances providing it is simply a case of fitting the appliance and furniture doors. Any additional work to the kitchen units or carpentry work required will need to be completed at the customer’s expense.

The GND Defender is designed to eliminate a "ground loop" that creates an annoying electronic hum audible through speakers or headphones. But keep in mind not all hum comes from ground loops. Most audio equipment, and particularly tube gear, may have some hum component in their "self-noise" (which is why S/N ratio is important). Hum is also sometimes the result of interactions between unshielded interconnects and power cords-induced EMI, and hence the advice to have signal and power cords cross at right angles. Induced hum is also a common plague in turntable, step-up transformer, and phono stage setups where grounding can be a real bedevilment. And as you are most likely aware, sophisticated (and expensive) grounding gear has become the current "Last Frontier" for noise-adverse audiophiles eager to invest in more cables and components. Note that all current measurements must be made using a true RMS meter. All 'normal' (not using a true RMS detector) meters use an average responding circuit, and this will cause serious errors because the waveforms are not sinewaves. Waveform distortion creates large errors with 'ordinary' meters. When toroidal transformers buzz, many people immediately think it has to be DC. However, this isn't always the reason. With so much household solar around today, it's quite common to find that the mains voltage is much higher than the nominal value (230V or 120V RMS). There's always an 'official' tolerance, which is typically ±10%. I've measured the mains voltage in my workshop at over 260V on occasion, but it can go higher than that.

iFi's approach to noise cancelling in cables uses inverse noise current to cancel out the noise in the mains signal. (Yes, comparable to the tech in noise-cancelling headphones). It has been installed for a couple of days now. I put it on the noisiest 250 and immediately, the hum was reduced. Didn’t cut it out totally, but reduced it so much, that you can’t hear it unless you put your ear right next to the amplifier. The other 250 is still slightly humming, but that was never as bad as the first one, so now I know that it works, I’ll get a second one. The SuperCap, FlatCap and the NAPSCs are all quiet. At Peter Tyson we pride ourselves on prompt, efficient delivery. Please note that the daily cut off time for all next day delivery services is 3pm. The Power Diodes prevent the capacitor seeing overvoltage during start up and during abuse. The diodes remain cold. Either in store or from the comfort of your own home. We appreciate life is busy, so why not let us make it a little easier for you.

Cute. Clever.

By reading past this point, you explicitly accept all responsibility for any such death or injury, and hold Elliott Sound Products harmless against litigation or prosecution even While the common solution found on the Net appears simple, there's a lot more to it than may seem to be the case. The operation is not intuitive, so while you may think that you know how it works, you could easily be mistaken. Also, beware of snake oil - there are vendors who will make outrageous claims about how their 'gadget' will improve the sound in mysterious ways, often accompanied by a 'technical explanation' that only qualifies as word salad.
