    On ackodac page it says “Price: from USD 680. Enquire”

     

    Regarding the new Ian’s clock comparisons @diyaudio, there is one nuance: they are directly comparable ONLY on same crystal when measuring the DUT.

    So, being fully transparent, he sould do such measurements when possible. And it IS possible with his new clock & drixo, for example. (And I bet he already did, but I doubt he would post the results)

    Otherwise, you can have a situation, where phase noise is limited by individual crystal piece, and NOT the schematics solution itself.

    This is what happened with canvas, I think.

     

    Andrea, did you measured several crystals out of, or maybe a even full batch (of ten?), to reckon a typical discrepancy of a batch made at factory?
