I'm considering buying a MBP. Everybody seems to be complaining about the screen (except for iW00t ). But there seems to be a second issue with the SR MBP, a problem with the analogue sound output. I've read one review (which I can't seem to find anymore), that was complaining about the (background) hiss and overall electronic interference sounds that shouldn't be there. The problem is that with all the sound in the stores, this is almost impossible to assess. Furthermore, I am confused whether all MBPs are affected or only a few, as I've only read two complaints about the soundquality in the forums. Could SR MBP owners, please comment on this issue? How bad is it using external speakers, IEMs and just regular earbuds?
