Good day fellow audiophiles. I'm having some issues with the sound output of my system. My amp is a sweet Denon AVR 5805 paired with Klipsch KG 4 as mains. HT sounds awesome and I couldn't be happier, but music playback at higher volumes is the problem. The horn tweeters are a bit harsh. I thought it was possibly the speakers, so I switched to some slightly newer KG 4.2 and the problem persists. Low to moderate volume is fine, but high volume is not. I'm not hearing distortion, but just very shrill and harsh highs. Is this a result of the amp or the speakers? Should I consider changing one or both? I really like the look of the Klipsch and the Denon has amazing surround processing. I'm just frustrated at this point...
