Hook the Nano iONE’s RCA analogue outputs into an integrated amplifier or a pair of powered/active loudspeakers and its internal, Bit-perfect Burr Brown DAC chipset will take care of D/A conversion. IFi Audio have sidestepped aptX’s dirty secret in the Nano iONE by specifying another CD-like codec – AAC – which is supported by iOS. Where this all gets a little fuzzy is with iOS devices – they don’t do aptX! Streaming from smartphone to receiver without aptX support at either end will see the Bluetooth connection revert to the inferior sounding SBC codec: bye-bye to ‘near CD quality’ Bluetooth listening, hello to an emotionally neutered Tom Waits and a tack-flat Kraftwerk. To realise the ‘CD-like’- (and not CD-) quality of the aptX, Qualcomm’s codec must be present in the transmitter (smartphone, laptop) and the receiver (streamer, DAC). Not all Bluetooth audio connections are born equal. Out of the box, a super-concise user manual ( here) goes large on minutiae.īefore we get going, we need to talk about Bluetooth. IFi Audio’s Nano iONE adds wireless (Bluetooth) and wired (S/PDIF, USB) digital audio handling to any audio system for US$199/€235/£199.
