how do they do it? 4tc vs Clear Oval

wait a month and switch back and see what you think, I have found the first impression often is the best but after a while you find out what is wrong with the new stuff (and things like fafafion points out) and the playing field is more even.

Thanks for the replies - Yes, I'm keeping the clear ovals for a little while so I can check my initial impressions. I've never heard much difference with interconnects, but with speaker cables it's been more noticeable...

I found 4tc's lifeless in my rig, so mostly anything else would be a improvement.

After a couple hundred hours of music, they will sound even better. Then switch them back for the Ovals and post your impressions. The 8TCs are even better. I've got them on the woofer section of my bi-amped system. Both have been around for a number of years and have impressed many with their lack of interference with the music.
