    The description of the change to the sound as ‘significant’ is an understatement in my opinion.

    This kit raises the performance level such that any fatiguing effects are now gone, resolution and detail are lifted to a whole new level and the dynamics are improved – all at the same time!

    Highly recommended based upon my purchasing experience.

    Want to thank you once again, a great upgrade! Well packed, perfectly built a great instruction and pro measurements!
    I wasnt really able to notice any improvement of internal DAC, but with spdif connected DAC sonic improvements of your upgrade are game changing.

    Recently bought a dCS Bridge had a chance to compare, and with your upgrade Bluesound sounds almost like 10x more expensive source. Would be great to upgrade clock probably to catch up the bridge, but no-one selling kits 😉
