Any diigital players out there with phase control?

I remember that Adcom had a CD player with phase (polarity) button on it and maybe a mono switch as well????.Wondering if anybody know of a multi format player that does as well?I assume I might be asking same qestion when we have just as we have but a few Bluray or HD players yet one migh hope same mnaufcturer recognizing someof us like this function will incorperate it on new decks.Be nice to have source do this so one could use preamp/passive box and not give there features up or if
Thanks
