I prefer to trade disc for disc to make the show trades even. I really prefer Disc-at-Once (DAO) shows only!! Good or better quality. Small flaws such as small ticks or variances in volume are acceptable, provided it is not something annoying that lasts throughout the whole show (buzzing, etc).  I try to have only the best sources for these shows. I'd rather not have track-at-once (TAO) at all, even the slightest hesitation between tracks! The exception to this would be demo's or studio recordings that aren't hindered by TAO playback.
I try to listen to shows as soon as I receive them, but if I have not rated a show, that means that I have not had the chance to personally listen to it and verify its quality or that it is in DAO. Normally my trades originate from fellow Warehouse members and I rarely have problems. Let's SHARE THE MUSIC.
