I second and third what Charles said about AC power. I do hope everyone reading this thread will try a high quality A/C wall outlet.
My personal favorites are the Furutech GTX and the Synergistic Research Tesla SE outlets. The SR outlets are fun to try as they have a 30 return policy.
I do think upgrading the main power fuses for each piece of equipment and upgrading the wall outlets should be done prior to auditioning various power cords and interconnects. This allows one to hear the maximum benefit of a cable change.
Last night it was live music for 100 people at the season ending concert for El Paso Pro Musica. Beethoven piano sonatas x two plus Bach. No written music on the stand. Just straight ahead playing. The artistic director of the series is Zuil Bailey. His Cd 's showcase some of the best in cello playing. The SR Black fuses certainly do allow me to hear the fine details of Mr. Bailey's expressive playing.
