Mine are rarely sibilant with the genres I'm listening with. I've become quite addicted to Titan, most recently with DX50 headphone out, which is strange because I usually dislike that player unless amped. I haven't listened to much else going on 3 days now, there's something about Titan which ticks many boxes.
I've been considering purchasing another DN-1000 but I'm not sure. Do you still have DN-1000? Do you think it pulls away from Titan in detail? It's very awkward going off memory.
DN-1000 with the JVC eartips is still my reference IEM. I haven't heard anything else has better tonal balance under $1k, better than DN-1000. DN-1000, like my Beyerdynamic T1, they are instrumental for me, tools that I really need. Not just an IEM that I like the sound. If my DN-1000 spoil, I will buy another one.
I compared them, DN-1000 and Titan 1, still prefer the DN-1000 with JVC eartips. DN-1000 IMHO still better, with more linear tonal balance than Titan 1. Looking at the price difference with DN-1000, Titan 1 is good for the price. I do like Titan 1, but so far only for certain recordings, not for closed miked vocal. Titan 1 is good for certain recordings that doesn't cause the treble peak on Titan 1 to show up. But with many closed miked recordings, sibilant on vocal is mostly always there.
I expect sibilance with many pieces of modern music these days. People should not be confusing recording sibilance with earphone sibilance. That said, the Titan 1 is a tiny bit prone to sibilance; for me the time course of it is very quick, so the sibilance is not bothersome. Rather, the overall brightness of the earphones can be a little off-putting at times. Most profoundly, however, I just don't feel a lot of emotion to the midrange, thanks largely in part to the laid-back midrange signature. To me, that would be the Titan 1's biggest weakness.
I'm not so sensitive to sibilant, mild to moderate sibilant is fine with me. But there are some who are allergic to even a very mild sibilant, so they need to know about the fact that Titan 1 is a bit prone to sibilant, in comparison to some of my reference IEMs, one of which is DUNU DN-1000. Most of closed miked recordings, whatever the genre, are more or less prone to sibilant. So distant miked recordings such as classical, and also many other modern genres, for example the famous jazz album, 'Jazz at the Pawnshop' which recorded using ORTF microphone setup, they sounds good on Titan 1. So at this time, unless burn-in will cause some changes to Titan 1, I would say Titan 1 is best for distant miked recordings, such as most classical recordings, binaural recordings, and other that used stereo miking techniques as the main microphones. The emphasized treble does bring classical recordings to live, that I really like.
