Being that the scene is based on obscure, rare, hard to find records is not the whole ethos of Rare Soul DJ'ing in the true sense of the word simply based on playing authentic original records? I take your points about spoiling records by playing them on sub standard decks etc. but in this day and age there should be no excuse for second rate equipment to be used anyway, a decent set of 1210's with top of the range Stanton's does help.
I still think vinyl is king for most of the scenes DJ's, although this might sound rather glib in my opinion records are for playing rare or not otherwise what's the point in collecting them in the first place? Of course it's important to preserve them but sorry I can't just look at them in boxes totally pointless.
