I have a noise that some on these boards have attributed to DMFW. I wouldn't call it a scrape or whoosh as does the OP here, rather more of a quiet rumble? Marbles in a coffee can, but very muffled? It really is difficult to describe, and in reading this thread I now wonder if we're talking about the same thing? What I hear is too quiet to record, else I'd post that here (and might make this post useless, but I thought I'd mention it anyway
)
