The first bootleg that I got was San Remo 81,with bad noise for a first bootleg, but I was so amazed by the interpretations of every song that I didn't care about the sound quality at all, only about the performance.
Most of the best performances recorded are on audiences recordings, so everyone has his right to want to listen only good sounding soundboards. Missing the best performances is the price you have to pay.
I rarely listen to soundboards.
