As a dowloader, I'd definitely pass on distorted recordings unless one or more songs in the set are rarely played live.
On the other hand, I'd still give a listen to a recording with missing tracks and/or occasional flaws (level drops, statics, cell-phone interferences, wooo-girls, local drunks, chatters).
I shared a tape once that was incomplete (got out of batteries after 50 minutes into the show) and got some occasional cell-phone interferences.
All of this was documented in the joined info file.
Got some nice feedbacks from people saying they were happy the recording got to be shared even so.
