I own a pair of the Meze 99 classics as well (bought in December 2018, so I assume I have the larger ear pads). I also bought a balanced cable to try with the FiiO Q1 Mark II but it didn’t make much of a difference to me compared to the stock cable and no use of a DAC at all (of course I tried several high-res files). So I returned the FiiO in the end. However I am thinking about enhancing my experience a bit now. From what I learned there is a possibility to upgrade the cable (original silver upgrade cable by Meze, which is supposed to enhance or balance the sound a lot) and/or change the ear pads to the smaller originals from Meze or the Brainwavz. What would you suggest? Start with the upgrade cable or going all in with the new cable plus the Brainwavz ear pads? I must add that I listen to music with my iPhone most of the time (2/3 256kbps streams from Apple Music and 1/3 high-res) where there is no Poweramp EQ, only in stock non-customisable EQ settings which also only apply to Apple Music and hence the sound of Ultra HD tracks from e.g. Amazon Music HD cannot be tweaked with EQ settings. Thanks for any advice!
