After reading this thread (and the one regarding Teo Audio), I purchased the Audioquest RCA splitters and an extra set of Duelund .5 meter interconnects. With about 75 hours on everything, I'd say vocals are even more immediate and haze free. To use a visual analogy, its like taking the screen off a window and you realize there was more clarity waiting to be discovered, but you never knew it was available. It doesn't change tone or turn something bad to good, it just opens it up a bit. Thanks for the advice Douglas.
