I've owned a pair of Polk Audio SDAIIs since the mid-80s. Finally made the move to upgrade. I'd upgraded other components of my system during the past 20 years and the Polks always seemed to step up and reveal the improvements - this includes recently going from ancient Monster cable to JPS Labs cable - I was shocked at the improvement that made. I've enjoyed the sound of these speakers - warmth with a decent amount of detail. To my ear their frequency response seems pretty well balanced and they provide reasonably good stereo imaging (with the interconnect and opposite channel drivers). I bought them used and consider it money well spent for the years of enjoyment they've given. Relative to pursuing increasing levels of equipment performance/quality, there is a point where source material and not component parts begin to have the greater impact on the quality of the music I hear. I'm not doing A/B comparisons of equipment when I listen and couldn't care less if everything I own isn't blessed by the Golden Ears at Absolute Sound and the like. I just want to enjoy the music. The Polks have allowed me to do that for a long time. You might be wondering why I'm upgrading if they were so enjoyable? When I bought my Jolida amp a few years ago, the dealer demo'd it using Totem Acoustic speakers. Hawks, I believe. They made an impression-especially how they seemed to disappear. The Polks do a pretty good disappearing act but are no match for the Totem's. At any rate - after a good long while I finally made the move and recently purchased some Totem Forests. Just breaking them in now (<25 hrs) though they sounded good out of the box. Totem imaging is more precise and bass tighter than the Polks. I've yet to really crank them up so am listening at what to me are relatively low volume levels. I do expect I will own these for at least the next 20 years. (Obviously, in terms of consumer buying behavior - I'm not what you would call an early adopter.)
