Well, I supposedly got suckered into buying a 300 dollar multi-tap with RF nodules some time ago after buying some new components and after having plugged the stock power cords into an el-cheapo multi-tap worth about 5-10 bucks. I was also curious if better quality cords make a difference sonically. What was my discovery? They most certainly do. That one 300 buck multi-tap effectively lifted the music to a far greater presence than it had before. This wasn't wishful thinking. I was very prepared to be disappointed. My ears, however, were not.
Cables make a huge difference. Period.
