    Jcat launches the new, 'Femto' USB card

    Good news for those of us are running PCIe/USB cards.

    Jcat has just launched their new card, that uses superior, ultra low nosie crystal oscillator (XO or just clock), chance the name 'Femto' (from the amout of jitter the XO has, measured in femto seconds).

    The card uses the excellent Crystek CCHD-957 XO, which can be found in Berkeley Audio Designs products and many other, top end DACs.

    This clock is very expensive at $30 in OEM pricing, which is many times the price of the regular XO used in most of the DACs (common XO cost more like $1-$5), but its specs speak for themselves. The Crystek XO features a typical low close-in phase noise of -100 dBc/Hz @ 10 Hz offset, and a noise floor of -169 dBc/Hz. That is super clock teritory.

    The Crystek Femto Clock which is located just a few millimeters away from the USB controller chip, which is powered by a dedicated ultra-low noise linear regulator for maximum performance.

    The whole power regulation has been redesigned as well. In the previous revision of the JCAT USB Card, the USB controllerís digital core 1V power was supplied from the PC via PCI Express lane. The card was redesigned so that all internal circuits are powered by ultra-low noise linear regulators exclusively, if any 5V power supply is connected (either external or internal).

    I read this..
    But also so the same clock is going to TCXO 10/100 Audio Grade Ethernet Switch, which "minimizes jitter & provides excellent sound quality".

    What is this femto clock for? This is not an audio device

    It clocks the USB chip.

    I don't think the router they are selling is their own design. I believe they source it from PPA.

    In Korea, there is PC Audio Club. The manager is very brilliant and passion.

    His ideas and opinions make JPLAY 6, Audiophile Optimizer, Entreq's Atlantis line, JCAT Products.

    (His name is Seung-Hyun Yoon. You will not trust me right?^^ Check it his existence to ask to JCAT)

    In fact, JCAT had schedule to import Yoon's recommended product. (general JCAT USB Card + Sound Prime's C-Clock)

    C-Clock JCAT is better than Femto USB, but C-Clock JCAT's look is so bad. (C-Clock JCAT's photo will upload tomorrow.)

    So JCAT confirmed Femto Clock installation.

    2 weeks ago, JCAT sent modified Femto JCAT USB Card, but Yoon and PC Audio Club's audiophiles are disapointed. ha ha

    I let introduce products that is made by Yoon's Idea.
    Dear Esotar,

    Not sure if you realize it, but your post puts me and Seung in a bad light and more importantly is far from truth.
    We're friends with Seung for over 5 years now. He's made JPLAY & JCAT very popular in South Korea, but he does not 'make' JPLAY or JCAT. I'd have known, I can assure you. Also I have not imported a single C-Clock JCAT card - where did you get that from? Sound Prime sent me a free sample for evalutaion and that's it. I never offered it to anyone
    And finally I have not received any feedback from Seung yet and am very doubtful it will be negative.

    Regards,
    Marcin
    CEO of JPLAY/JCAT

    PS
    I'm not sure what is your relationship with Seung, but I kindly provided him the link to your post

    JPLAY is the best product for PC-FI.

    But JCAT is not good.

    Your company will try much harder.

    I hope JCAT is the best brand for PC-FI in the world.

    I am Seung-Hyun Yoon and have just registered in WBF after Marcin's e-mail.

    My positions are very clear & simple.

    - The Femto USB card is still in burn-in stage for last 3 weeks and have no feedback yet. Need 2 more weeks to burn-in. Because comparison targets have been used for years.
    - I have tested and share my feedbacks, but never made JPLAY6, AO, EntreQ Atlantis line and JCAT products.
    - Sometimes, exchange opinions and share ideas with audio gear/cable developers as brainstorming. But actual products are made by developers.

    I wish this thread back to discuss about New JCAT Femto USB Card.
