A nerdy guy with a passion for audio and gadgets, he likes to combine his DAC and his swiss knife. Even after more than 10 years of experience, Nanotechnos still collects all gear he gets, even his first MPMAN MP3 player. He likes spreadsheets, technical specs and all this amazing(ly boring) numbers. But most of all, he loves music: electro, classical, dubstep, Debussy : the daily playlist.

    Hey, was wondering if you’ll do a review of the AM3D module, since it has that THX amplification technology stuff, and the M11 Pro. Also, is the Q5S more portable than the M11? You wrote you thought the M11 was a little bit thicker than you’d like for portable gear.

    It’s hissy as fuck. You won’t notice it on normal music, true, but try listening to classics. Piano for example. 16 Om headphones would be hissing, including FH7.
