I picked up two pairs of Wywires RCA interconnects a few days ago. I haven't really had a chance to listen to them today, but I've got a friend coming over tomorrow, bringing some Audioquest IC's so I needed to get cracking.
My wife is out of town, so lots of things are possible. I started with a really nice LP, Jennifer Warnes "The Hunter". Just threw it on the table, kept my old IC's in, no diffusion in place, coffee table in front of leather couch... nothing optimized, and it sounded like it. My line sources can overpower the room easily, and the song "Way Down Deep" just did its boomy thing at about 120Hz.
So I put the diffusor panels in place in front of the big screen, and a second pair forming forward wings outside the speakers. Things improved. Moved the coffee table, things improved. Changed to the new/used Wywires silvers, things improved. Moved the couch back to open some space, switched to classical. Hi Q recording of Rimsky Korsakov Capriccio Espagnol. Took out the leather couch, moved in a cloth covered love seat. Things improved. More space, more detail. Changing the seating furniture is clearly an improvement.
Next turned out the lights, and poured myself a hot cup of coffee. Don't know if the music was better, but I enjoyed it more.
Everything makes a difference...
