Mrtennis,
I'd have to respectfully say that your issue lay elsewhere. The Jolida is one of the most responsive units out there to changes, be it tubes, cords or board modifications. As for harshness, I haven't found that to be the case at all (stock or otherwise), but I did note that seems to be your opinion about CDP's in general.
Is the Jolida the end all of CDP's? No, not even close. In stock form, for the money, with different tubes and power cord it is a decent unit.
I modified mine, heavily. Is it as good as my reference? No, but it does sound pretty damn good in my office rig.
