QA needs to be tightened

Just received the device, it works as advertised and I'm satisfied with how it sounds. There is, however, some unfortunate oversight in the design of the volume/mute knob as it tends to scrape against the case when turning and sometimes the press action (mute) is not registered.
Also, my unit arrived with deep scratches on the display (no protective film applied whatsoever) and missing accessories (no opt. cable, no RCA cable, no 6.3/3.5 jack converter). Pretty annoying since these defects and discrepancies could be prevented/screened by a simple QA check at the packaging process.
