    Astell&Kern AK120 II reviews

    AK120 II Portable High Definition Sound System (Silver) is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Amazing Sound Quality I just wanted to write a quick review. I also upgraded to this unit from a Fioo X5 1st gen player. The sound quality is on an entirely different level---an astronomical upgrade. I also had the Bit Opus 1 for a month before sending it back and buying this unit on the site used. The Opus was really good but nowhere the sound quality of this unit. I hear details I never heard before with the 120 II. The volume is pretty good on its own but I pair it with a Fostex portable tube amp at home and a chord mojo for the gym---serious audiophile gear. IF you can afford this unit---buy without hesitation--it really is fantastic, as good as it gets at this price.

    Rated 5 out of 5 by from Exquisite, delightful, seductive, pure audio indulgence A+++ Just received this AK120II which I have been contemplating in purchasing for some time now. Got a great deal from B&H used but nontheless, exceptional in everyway. I am a novice audiophile so let me just say that this review is no where near objective but providing my feedback from another DAC I has previously which is the FIIO X5. First off, I like this one since it has a nicer interface and it's a capacitive touch screen. It's more sexier than FIIO and superior in every aspects in terms of aesthetics and audio fidelity. I am not going to bore you with all the technical terms, but if these two music players were edible delicacy we all know, FIIO would be a can of Starkist Tuna and AK120II would be a fine Russian Caviar--exquisite in every respect. So, if you have not owned one and you think FIIO was a great player, than AK120II is just so .... oh yes! BTW, I use this unit with Grado Prestige 325e and 10e.
