I tried using Harmonic Technology Pro-9 speaker cables on an Almarro tube integrated (20 wpc). The sound was thick, slow and no treble. I changed to some Nordost Blue Heaven I had on hand and the sound was transformed! Literally night-and-day. Interconnects are designed for a (relatively) stable environment (line-level voltage).
Power cords? I've never had an "ah ha!" moment. All-in-all I'd go with speaker wire makes the biggest difference (note: The Harmonic Technology is wonderful with high-power SS amps).
