Exclamation [Q] Speaker grill hole and Sound quality problems

Hi Everybody,

is anyone else noticing the speaker grill hole aren't completely drilled through?

Also,
much more importantly,

is anyone else hearing a metallic grating noise when sound is played through the speakers? This isn't just high volume distortion, its constantly present even at low volumes. Very shrill, ratchety, and really annoying. Hoping to return and get a new unit if I'm not the only one with these problems.
