The device ships with these plug adaptors to spread around its luv to more kit that slurps its milkshake through a switching wall-wart straw.
Worship of self. When more enlightened future times look back on 2023—if humans still populate Gaia by then—one hopes that the selfie era's inane obsession with living through the eyes of others will have dropped. If so, the current craze about all iThings will have evolved into something more inclusive so less self-referential. Of course it still is 2023 so today can be all on about iFi Audio's DC iPurifier2. Which arrived by iMistake. I'd ordered a second iPurifier3 to put back into the below desktop system after…
… I'd moved my unit into the main downstairs system. But as I told my iFi contact Victoria Pickles, I'd find a place where to stick their erroneous arrival. The below Singxer SU-6 USB Bridge was one potential destination. Its DC input simply charges ultra capacitors which then power the circuitry. If the snazzy white metal doodad could do anything audible, it'd have to be cutting UHF hash which made it past the virtual batteries to still interfere with the actual signal path. Was that even possible?
Rather more needful of noise-killing ministrations seemed our fiber-optic router from whence all our computers hardwire via up to 30 meters of industrial CAT8a cable. Affixing my evil eye on it, I added a horned hand tribute to really let it know what I thought of its audio credentials. That's one significant finger different from a chilled shaka brah; and one finger more than Johnny Cash's eternal salute. I grabbed an adapter plug. The iPurifier2 otherwise wouldn't seat in in the router's smaller power inlet.
Reflecting decibel's log scale, iFi promise us noise reduction from 316 to 100'000 times across 1Hz to 5GHz. If anything in our digs needed such help, it had to be the generic router from our domestic telecom company. With proper Irish petulance, it returned my maloik right back. Even though the adapter plug seated fine, the iFi's red power light didn't wake. Rebooting the router's SMPS didn't help. Its own power LED right on the wall outlet refused to alight as long as iFi were in the game. Once they unplugged, all was well and we online again. Drat. Unexpectedly the DC iPurifier2's 5-24V/3.5A rating and our router refused to get on. Was I down to massaging my super caps? That didn't read properly catholic. A quick think identified one more DC input in the main system; that on the tail end of my icOn Gradient Box smart crossover. The iPurifier2 had its marching orders for a two-pronged pincer attack. Or so I thought. Upon closer inspection, I was reminded that the Gradient Box AC adapter uses a 2-prong locking connector. The component does feature an alternate 2.1mm power port to give aftermarket linear power supplies an entry. I simply didn't have a wallwart of the correct value to use there with/out the iFi. Downstairs was down to a single experiment: massaging those super caps. For less questionable fun I'd have to go upstairs.
