I have quite a few D2D LP's that I bought new. All D2D LP's were/are limited editions. With D2D two, three or more masters are cut live. You can only make so many stampers from a master disc. Stampers themselves have a limited life span. Each stamper can only press a finite number of LP's.
Some of the D2D's were reissued using the backup tapes as masters. The reissues sound very good but they don't sound as good as the D2D's. Many D2D's including several Sheffield Labs have been called some of the best sounding recordings ever made.
