Do you really price match?
We will match any e-Commerce (Online store) Authorized USA Dealer's advertised price. Please call us toll free (877) 370-1972 and alert us to where you found the product cheaper. We will verify, and if the site is an Authorized US Dealer- we will match their price. However, if the price is below the manufacturer Minimum Advertised Price (MAP)- we will have to get authorization to match the price. We will not violate our signed agreements that we have with our vendors.
What about price matching from an auction site?
We do not price match any auction or "grey market" site.
Be advised, any purchases from an auction or unauthorized (grey market) websites can lead to future issues in regards to warranty or support. Most manufacturers will not honor any claims or warranty from these type of sales. Spend your money wisely by purchasing from an Authorized Dealer. In a lot of cases, saving a little bit of money can cost you more after the sale is completed.
We offer a 30 Day Return Policy should you choose to return a product for any reason.
Since 1972 Sound Approach has backed all items that we sell. If the product you have purchased is not right for you, let us know. We strive to find the right product for your unique situation. We will work with you to find a sound solution and recommend what product will resolve your issue. That being said, we will credit, refund, or exchange any product you purchase within 30 days of your purchase.
Certain products, may be returned, but are subject to a restocking fee of 20%. Please contact us to determine, before ordering, if the item will fall into this category. Usually it is for the high-end electronics & audiophile-grade speakers. We want to make sure that we match you with the correct product, so please call and speak to any of our technical experts prior to ordering.
Four Important Conditions:
1. We need to get the original box, manuals, and any materials that came with the product for you to receive a full refund- with no re-stocking charges. The item/product must still be in like-new condition.
2. If the item had Free Shipping and you are returning a non-defective product, the original shipping cost will be deducted from the total that will be refunded back.
3. Special Ordered items are not returnable (see below).
4. Once an RMA is issued- it is valid for 10 business days. After 10 days, the RMA is canceled and returns will not be accepted.
Shipping and handling charges cannot be reimbursed unless it is our mistake. Yes, we can make mistakes – not often, but it can happen.
iFi Audio - DC iPurifier - DC Power Noise Reducer
With trickle-down technology from Abbingdon Music Research (AMR), the very latest product from iFi is the DC iPurifier; a noise-cancellation product aimed to enhance the existing, ubiquitous Switch Mode Power Supply (SMPS).
Generic SMPS designs are very noisy because they were never intended for audiophile applications.
The DC iPurifier sits in-between the SMPS and the device such as; router, DAC, set-top box, media streamer, laptop or desk mixer. And with the latest Active Noise Cancellation® technology, from 5 volts all the way up to 24 volts (up to 3.5 amps) the DC iPurifier sharply reduces noise to improve the quality of the device.
Got SMPS? Just add the DC iPurifier
Generic Switch Mode Power Supply designs are noisy – but they were only intended for mainstream use so noise was never a consideration. Just insert the DC iPurifier between the existing noisy power supply and the source; noise is reduced by a factor of 316x to 100,000x.
Be it home or professional audio, this is the most simple and most effective way of improving audio performance from arguably, one of the noisiest sources in a computer audio system.
Active Noise Cancellation® derived from military radar technology
Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation® (ANC®) audio power system.
An enemy air defense radar will transmit at a certain frequency; when the enemy signal reaches the aircraft, a receiver on board the aircraft will pick up the signal and a computer will analyse its base frequency/modulations and produce an identical, but an out-of-phase signal to cancel the enemy radar signal.
By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC® is the perfect ‘antidote’ for power supply noise, the bane of all audio systems.
Across the audible range, measured noise is improved by 316x to 100,000x or by 50dB to 100dB respectively.
Sonically, the background and inner resolution to recordings is brought to the fore and no longer hidden. Sonics are much smoother, just like how good analogue should be. Nothing comes close.
Ultra wide-band design, effective from 1Hz to above 5GHz
iFi leaves no stone unturned; the DC iPurifier is a ground-up, ultra-wideband design.
Effective from 1Hz all the way up to 5GHz. Crucially the strongest performance is in the audible range of 20Hz to 20KHz.
Built-in polarity protection
Red protection LED will be lit if the input polarity is reversed (If reversed polarity, please correct).
Compatible with all power supply designs 5V-24V/3.5A/84W
The DC iPurifier handles 5v through to 24V. Takes up to 3.5A or 84W. For different types of DC barrel connectors, the DC iPurifier works with 5.5 x 2.1mm but also ships with adapters for 5.5×2.5mm and 3.5×1.35mm. These three fittings cover the gamut of DC barrel connectors.
Professional audio applications typically require a ‘center negative’ power supply. To lower noise with the DC iPurifier, use a ‘center positive’ power supply at the input and use a special white ‘inverter’ at the output.
