That is such a good book. As knowledgeable as you might think you are,
there's always something in that book that will surprise you. For
instance, I started using a wireless router a couple of years ago and
didn't even think it could affect the sound of my system. It did.

Yeah, that kind of thing is good info. In my case, my wireless doesn't
affect anything sonically (that I can tell). However, if my notebook is
plugged into the same circuit it does produce some noise. And, there's a
dimmer switch that seems to adversely affect the sound quality, too.
That's all stuff I wouldn't have thought about exploring until I read
the book.
