I bought a Beam 2 seven month ago, and the last couple of months the Beam is developing a tinny metalic sound in talking/voice sounds (playing music is still fine, but I think other frequencies are used there, I am sure there is technical / scientific explanation for it). Here is a sound sample example of it:
This is a clip/fragment from youtube: Sonos Era 300 + Arc & Sub: Ultimate Home Audio Experience? - YouTube
So I found my self more or less forced to buy another new soundbar from Sonos (Why not another brand?; it was black Friday and I already invested in two subs and 2 Sonos surround boxes which are 1500 euro worth, and I hope it is a rare defect) which does not has that problem (and I did not also perceive that distorted effect at other cheap desktop speakers and other (Sonos) speakers, that I possess ).
The distortion was less when I placed the sound bar on soft fabric tissues, but unfortunately that did not solve it enough. Anyone an idea what kind of defect it is?
