I am sorry if this comparison has already been posted, but I can find nothing. I recently purchased JHA Layla CIEMs and they are delightful. I am looking for a portable DAC dongle to use with my iPhone and Mac Book Air as sources when not listening on my desktop system. A friend leant me his FiiO KA3 which performs nicely but I am interested to hear from anybody who has directly compared the sound of the KA3 with the relatively new AK HC4.....any input you can provide?? THANKS!!
