Coping in an Age of Uncertainty

there have been numerous threads here, i know, about sacd v. dvd-a, upsampling, oversampling, etc. a number of these threads have included discussions of which, if any, new digital format will replace what we now call “redbook” cd’s. i don’t wish to rehash these discussions. rather, i’d like to hear from others how they are coping with the “age of uncertainty” in the realm of digital audio. is it better to “roll the dice” and invest in sacd or dvd a? ignore the contenders for the new and get the best possible out of redbook cd’s? buy with upgradeability firmly in mind? follow another path? i don’t post this query out of mere curiosity. i really haven’t figured out what course i should follow. i’d appreciate your giving me a hand. -kelly
