Japanese Zep CD's-the sound remains the same

page did not oversee the manufacturing process, and the fact is some plants make better sounding cd's than others. all pink floyd discs are made at certain approved facilities. the band has the ability to block manufacturing if they choose. the mini-lp discs manufacured in japan are of a higher quality than the u.s. versions even though they are derived from the same masters and may (from title to title) may not be dramatically different.

i've been involved in the production end of audio and video for two decades and know the faciility standards from one manufacturer to another are not the same..... and it does have a direct impact on the sound and picure of discs even on the same title....as well as the shelf life....google and research......in many ways there are similarities to the glory days of vinyl.

one more thing and i'm out....there are numerous manufacturing and stability studies that have been done on optical discs new and old. most of the time you do get what you pay for with software....even of the prerecorded music variety. there are things hi end hardware can't cure alone. enjoy zepplin no matter matter the country of origin

compact discs and dvd's are different depending on label and facility specifications. even the manufacturers of the plastic and metal used to make the discs are different in terms of standards. the color of the metal used even changes the sound(those gold discs aren't gold for no reason). contrary to what many believe, a cd isn't made to last forever, and a good deal of how long it lasts and how long it sounds good is determined by the standards it was made under. rot and loss of information are two real problems that do exist in both formats. there are even solutions and polishes that aid discs that exibit errors. masters and dlts are affected by climate and handling as well. the average cd now costs less than 40 cents to make and a dvd9(dual layer)is well below one dollar. gold as opposed to silver adds significent cost and it isn't just because it looks cool. the playback levels set for volume etc. etc. it all has just as much effect on sound or more as ditching one 99% pure copper wire for other one.
