In sound quality terms, is much to be gained by keeping Shunyata power cables as short as possible? Using the most convenient wall socket for a Delta NR cable I am thinking of getting would require me to get a 10 foot cable. But a standard length cable would be fine if I used the wall socket nearest to my equipment rack, which would require a bit of creative thinking in terms of equipment and cable positioning (some touching of power cables in this instance might be unavoidable). Thanks.
