IEC's are strictly a matter of convenience. Personally, i find them WAY underspec'd for audio use, especially on power amps. Not only does the use of an IEC double the amount of point to point connections made in the circuit, most are not rated for ANY type of "high current" use. If you are shooting for the best performance of ANY component, a hard wired cord is ALWAYS superior to one that uses an IEC connection. With that in mind, hardwiring a chord is superior so long as you can do it safely. Sean
