iFI Micro I-DSD The ‘Octa-Adopter’ 512 units

iFI Audio launch the i-dsd micro DSD/DXD DAC and headphone amplifier. There is nothing like the micro iDSD. It is literally, out of this world. It is the only DAC in the world (at any price) to play True Native Octa-DSD512/PCM768/Double DXD. Its Perfect-Match means it can be fine-tuned to any headgear from IEMs all the way through to large headphones. Its 8v/4000mW output makes it one of the most powerful headamps to drive even the most hungry of headphones with ease.

For those of us (me included) who are not technically inclined this little box will do many things and all of them well, headphone amplifier on the go (portable as its battery powered) or as a static headphone amplifier for those late night listening sessions at home, just attach a source like a cd player, its best secret is the built in DAC which plays almost every file known to man, so download some hi-res music files 24/96, 24/192, DSD, DXD etc etc and play them via a laptop or pc, the DAC connects to your hi-fi system and can be hidden behind your rack, totally future proof and sound quality to die for. AND ALL FOR UNDER £500
