As someone who just built a system, I decided to consult folks here. The smarter ones indicated that (above and beyond surge protection) it could make a sonic difference, but so much depends on (a) the electrical on that line, (b) at that breaker, (c) in that house, (d) in that neighborhood.
Given all that, the question becomes, what are the objective criteria with which *you* could measure *your* particular electrical situation?
And then, what results would indicate something which could, in theory, be noticeable?
And assuming you figured all that out -- and let's say for argument that you found something which could be noticed -- the next question for you would be, "Is this the next most necessary thing I need to do to improve sound in my system?"
