Yeah, I'd concur that Paranoid, indeed the first few Sabs albums are beautifully recorded. Really natural sounding, noting too mucked about with. Amazing really when you consider how quickly they were laid down. If you're not feeling it from those then, yes, you probably need ot tweak something.
Also try Led Zep II - great dynamics and nice production.
I'll also always vote for Wishbone Ash's Pilgrimage - again a beautifully produced record. Fantastic sounding bass and drums.
