This is a buyer’s market: £50 is a strong deal for an iPurifier3, sitting just above the £49 25th-percentile mark and well below the £57 median from six recent comparables. It is comfortably within the normal range, with enough saving to make this a worthwhile punt rather than merely a fair buy.
The iPurifier3 is a compact USB inline filter/reclocker, combining active noise cancellation with REclock, REgenerate and REbalance circuitry to tidy USB power and signal integrity. It can be particularly useful in a revealing DAC setup where computer noise, grounding issues or a rough USB implementation are audible, though system-dependent gains are inevitable. Since the condition is unknown, confirm that both USB connectors are clean, the LEDs work and the original adapter or packaging—if supplied—hasn’t been lost; at £50, that uncertainty is still reasonably priced.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
iFi Audio is a British hi-fi technology company founded in 2012 by Abbingdon Music Research (AMR), a prestigious manufacturer of high-end electronics based in Southport, England. The venture was conceived as a way to democratize advanced AMR engineering by applying proprietary technologies developed for premium home audio to portable, more affordable devices. This strategic pivot proved remarkably successful, establishing iFi as a bridge between audiophile-grade sound quality and accessible pricing.
The brand specializes in portable and desktop audio components, with a product portfolio exceeding 50 devices spanning DACs, headphone amplifiers, Bluetooth streamers, music players, power conditioners, and cables. Flagship products include the iDSD Micro, Hip DAC, xDSD, and xCAN amplifier, all engineered to deliver high-resolution audio support and studio-quality fidelity in compact form factors. iFi has also gained recognition for innovation in wireless audio, notably with their GO Pods earphones featuring xMEMS technology and their Bluetooth-enabled DAC/amp solutions.
iFi occupies a distinctive mid-to-premium market position, offering audiophile-caliber performance at entry-level to mid-tier pricing. The company sources components globally from Germany, Japan, and the USA, and employs proprietary technologies such as PureWave balanced circuitry to minimize noise and distortion. Rather than competing in the ultra-luxury segment, iFi targets discerning listeners who demand measurable sonic improvement without premium price tags, making it a trusted choice for both portable and desktop audio enthusiasts.
