Much to my dismay, I've been seeing more and more high-res versions of out-of-print Mobile Fidelity releases that I've acquired throughout the years. This brings me to my question...do I get start getting rid of the coveted MoFi discs that I've searched long and hard and paid a good bit of money for? I've built up quite a collection and am concerned that if I wait too long, the value will drop and they'll be worth only a fraction of what I paid for them. I could sell off those that have been recently re-issued (for example, "Dark Side of the Moon") and reinvest that money into the high-res versions if they are worth picking up. Or, do I hold onto them and hope that these things are worth something in the future, perhaps on Antique CD Road Show?
