There are many members who have been helpful and friendly. Shoot an email to most audiogoners and they'll generally take the time to reply (unless they happen to have ruthless email filters!)
Mike Lavigne, Tireguy, Panorama have taken the most time to share their experiences with me (or perhaps it's because I bother them the most). Jtinn, although he does not fit into your criteria as he has commercial interests, has always given me advice without much regard to what he carries.
I think there's an "expert" for every musical tastes around here, so you'll easily find someone who is knowledgeable and shares similar tastes and thus their advice becomes invaluable.
