Let’s face it, power can be noisy—so if your power is introducing unwanted noise into your audio signal, then you might want to check out this line of power purifiers. If you need to use a device without sonic hindrances, iFi AUDIO has you covered whether you’re looking to clean up signal juiced via USB Type-B, USB Type-A (especially useful for giving your DAC a little extra fidelity) or through any noisy VDC power supply. This item, for instance, boasts many different adapters to better suit the various barrel sizes of oft-noisy switch-mode power supplies, and does so while bringing the noise-floor down.
Then again, perhaps you’d prefer to cut out the middle man and procure an ultra low-noise power supply in its own right? Then check out iFi’s models of AC/DC units, available for 15V, 12V , 5V, and 9V. They all boast a whisper-quiet noise-floor of 1uV, as well as active noise cancellation, five different barrel tips, and an included polarity inverter.
Maybe a you’re in the market for a portable headphone amplifier—one that eliminates output coupling and has options for delivering a thunderous bass response and excellent stereo separation? Then look no further than this unit, which boasts 3.5mm and RCA inputs. It’s suitable for use with high-end portable systems and home rigs alike.
