I was planning on getting a pair of Polk LSI 15s for 2 channel stereo music listening to go with an Adcom GFA5500 200 watt per channel power amp I bought recently used, along with an Adcom preamp. However, I've came across the chance to buy a used pair of Klipsch KLF 30s locally that are in great shape for a reasonable price ($1000 for both, and I could probably beat him down even further than that if I really tried). Price notwithstanding however, which would be a better speaker for hard rock/heavy metal music paired with that Adcom amp. I seem to vaguely remember a post recently about Adcom amps not being a good match for KLF 30s since KLF 30s are a very bright speaker (even for a Klipsch, which is really saying something). I already know that the Klipschs will obviously play a lot louder than the Polks, but would the KLF/Adcom combo be too bright to the point that its piercing and painful to the ears, and the LSIs would be a much better match? Or would the KLF 30s be ideal for that type of music with that amp (after all, they call it "the rock and roll speaker").
