I'm experimenting with elevating my speaker cables, using Mytek boxes as the lifters. I'm playing an M+A Recordings CD of Sera una Noche DAC'd through the Mytek BB. Right now I've got the cables lifted. Yes! A whole world of difference! Well, maybe a reasonably discernible world of difference. A bit more image width and depth if not specificity. Maybe a bit more life in the female vocals. Enough of a difference to keep them elevated for a while.
