    So this DIRAC seems to be the very first IEM incorporating this new SF - Super Fidelity DD from Sonicast.
    This dynamic driver supposedly has near perfect control over surface split vibration. This enables driver to
    reproduce very high frequency over 10khz with low distortion.

    This IEM is not released yet and currently in pre-order stage. I believe they will be available later this month in Korea.
    Currently, I could not find any place that ships this to Canada, so I asked my friend in Korea to forward me few sets.
    So yeah.. I haven't heard it yet, but few credible source (reviewers at seeko and beta testers) told me they sound pretty
    amazing for any price, but at suggested retail price of US$42, staggeringly good.

    Just looking at frequency response, I wish they will release something with slightly tamed bass by around 4-5dbs in near future.

    International shipping is not available here though. I will try to search other shopping sites where they might carry and ship them to CONUS.
    When I receive mine and if I feel if it's worth it, I will start a US-Canada tour and send another pair to james444 for him to try his usual modding fun.

    Hmm, I think if you remove the words "quite" and "revolutionary" from the title then it'll be more accurate.

    What's low distortion and lack of driver resonances worth when you have such a screwy FR? Looks to me like yet another IEM voiced based on looking at graphs instead of listening to it.

    Thanks. I'm in South Korea so shipping isn't an issue, and for 47,000 KRW it's worth taking a chance on something interesting albeit not revolutionary.

    Cool. My bad on title, I got little carried away. Hope you can share some initial impressions with us when you receive yours.

    Ok It took long but finally received this IEM as they were immediately sold out in Korea (close to 5,000 units apparently) in their 1st / 2nd run and I missed out on both of those chances.

    Initial impression:

    Good:
    Sound quality is excellent. I was worried that bass might be too much, but it is not as bad as I thought.
    Bass is tight, snappy and linear in its delivery yet I still think about 3-4 dbs cut below 125hz would have been ideal for my taste.
    Good resolution across presence area, mids are quite neutral, clear and accurate sounding with a slight increase in energy beyond the 3-4k marker compared to the lower mids. Treble is clean, articulate and throwing out perceptibly pleasing levels of detail. Timbre is very good.
    Overall, I am enjoying this more than any other IEM at the moment (my current rotation includes: modded BW-ES1, Andromeda & Isine20)
    Isolation is really good too (near -25dbs) as there are no vents.

    Bad:
    Cable is prone to microphonics and sub-par in build quality. Y-split is made with a shrink wrap.
    Soundstage is about average for an IEM. Got too used to Andromeda and isine20s spacious staging I guess.
    Slight pressure build up in eardrum with certain eartips.
