I thought I'd post some updated impressions about my Harmony's since I've finally had some time to spend with them after my refit adventure; Mostly because to my ears they do sound a bit different than I remember when I demo'ed the universal version during the tour, and it differs from my informal review over in that thread a little. First things first, the bass has slightly higher quantity to my ears compared to the universal. In fact, this was my only real nitpick of the demo, because on certain EDM tracks it could occasionally lack some warmth and slam that I categorized as a "lack of a traditional mid bass bump in the tuning" (which was odd to me considering this is a warm and organic headphone). This isn't really the case any more, and I find that the custom version offered much of what I was missing. Piotr told me that my ear canals are oddly shaped, so it seems to me that that was perhaps causing some attenuation of the bass. With that said the overall signature is slightly altered due to this, and it seems slightly more natural sounding (though this isn't to say it didn't sound natural before) and a bit more linear - fuller to my ears. I was surprised by this, as I was told the customs should sound nearly identical to the universal. I don't think that the Harmony's are negatively affected, and impressions are just as strong as before, ie: not a massive difference, but enough. Since I'm going off of months old memories, it might also be that I hear the treble as slightly more laid back as well compared to initial impressions, but I'm not certain. Overall it seems to be even more organic and even-tempered than I originally heard, and they are just as great - perhaps even better now with a refit and some burn in. It makes me want to try more of what Custom Art has in their lineup to see what wonders are there
