The Synergistic Research Galileo LE speaker cables showed up yesterday.
First, let me thank folkfreak for suggesting in a private conversation that my electronics may have surpassed my cables and accessories. That comment inspired me to seek out the Galileo LE.
So, I've been comparing SR Galileo LE to SR CTS. Totally they seem about identical. No added bass or more extended highs. But I did notice a bit more richness in the midrange.
The biggest difference seems to be spatially. The air around instruments, and the interaction between instruments. Its more realistic with the LE. Its an old analogy, but its like the pane of glass has been cleaned. There also is more depth to the sound field.
The other significant difference I heard is bass control. Its better through the LE. Less resonant and more clarity.
The two cables do sound quite similar and its obvious they come from the same family. But I see significant improvement with the Galileo LE, with no drawbacks, other than the cost.
