I know this question is gonna cause trouble. , but I own a pair of older polks RTA11-T from the late eighties. What IVe noticed is the newer polk line Ive recenty auditioned at Circuit City dont really sound any better at all to me. I know im not biased, cause I fully expected to hear a difference of at least some degree. My hope was to upgrade to a newer POLK just for the heck of it. In my humble opinion, they sounded actually more "grating" sounding with a bit more boomier bass. Mind you this is a half hour quick listen, not an extended blind side by side test with my older speakers. MY question is: does anyone here agree with my accessment or am I imagining this differecne??....I cant imagine POLK hasnt improved in over 13 years....But the ones I own really sounded fantastic at the time or purchase, so maybe a big improvement wastnt warranted or practical in the under $1000 pair range.
