Black Label micro iDSD Amplifier Top Seller in Japan

Southport, UK based company IFI has been making waves this year with their portable audio amplifiers and MajorHifi just got word that their micro iDSD Black Label Amplifier was a #1 seller this year in Japan. The micro iDSD BL is a handsome looking amplifier and DAC combo featuring the AMR Global Master-Timing femto precision clock system to reduce phase-noise and jitter. The micro iDSD BL has a Burr-Brown DSD512/PCM768/2xDXD True Native DAC enabling it playback of all music formats. The components are rich with high-fidelity parts like Sanyo OSCON capacitors, HCOFC copper lead-frames and 4N Gold bond-wire on the OV IC’s. The micro iDSD also has 3 output modes (Eco, Normal and Turbo) for different headphone applications as well as 3D and X-Bass technology. The battery will last 6-12 hours depending on the type of output needed for your headphone and can even charge your iPhone through the side USB port when not in use.

The micro iDSD BL edition is a powerhouse DAC and Amplifier that appears to be impressing even the most savvy tech customers making it a formidable opponent in the portable DAC/Amp market.
