Rockness87,
I had the same experience with the Nordost Blue Heaven, which I purchased the The Cable Company.
This cables made my system sound very thick. I tried to return them and the salesman at The Cable Co. (John Pharo) said they needed to settle in. Well, after 200+ hours, the sound was still as thick as day one.
I tried to return them again and John Pharo @ The Cable Co. never returned my emails or my phone calls. Other salespeople always forwarded my phone calls to his voice mail.
After many tries to return them, I ended up selling them at a lost.
I'm glad you found a dealer that's willing to work with you and that the new cables work well in your system.
