hi audiophile1958:
you can have a negative attitude toward a product initially, even if you haven't heard theproduct, if it is a member of a class of products to which you have been exposed and the result has been a dislike for such products.
for example, while i have heard many cone speakers, i am skeptical that i would like a cone speaker that i have not heard, based upon my vast experience with cone speakers.
it is highly unlikely that i will ever own a cone design. yet i have not auditioned every cone design.
when i hear of a cone speaker that is highly regarded, i am inclined to think i will not like it. of course, i would need to audition the speaker, to confirm my predisposition. however, i would indeed make a wager that i would not want to own a cone speaker, based upon a fair evaluation of that speaker.
