Hi all. So I recently bought myself a set of Harman Kardon HKTS-18 5.1 speakers along with the Onkyo 606 receiver. Overall, I'm extremely happy with the setup, but lately I've been noticing what sounds like mild distortion from the front speakers when listening to a variety of content (stereo music, Dolby Digital DVDs, Dolby Pro-Logic TV, Xbox 360 video games, etc.). 99% of the time, the speakers sound perfect, but this problem occurs very briefly during strong instances of mid-high frequency ranges, but it's starting to really annoy me, especially considering I never heard any distortion on this same content with my previous surround sound setup. I'm listening at regular levels, too!
I've tried adjusting every single setting on the Onkyo to compensate for this, but nothing seems to work! The self-calibrating Audyssey doesn't get rid of it, matching the sound levels manually using an SPL meter doesn't help, adjusting the EQ for particular frequency ranges does nothing, and lowering the overall treble level on the receiver doesn't help either. I've even played with the speaker distance settings and frequency crossover ranges in desperate hopes that I'd stumble onto a fix!
Can anyone offer any recommendations, please? At this point, the only other fix I can think of would be to connect my Xbox 360's HDMI to the receiver and get the sound directly from there (right now the HDMI goes straight to the TV and audio is fed to the receiver via optical), but I'm wondering if that would even make a difference? But I'd still like to hear any alternative suggestions before I try that. Thanks!
