AQ Earth interconnects..echo?

If you bought them from a dealer, speak with them and voice your concerns. Try both cables at the store and see if you are hearing the same thing there. The dealer should be there to help you with any concerns after the sale. If they can't help you, contact Audioquest directly. Even with a company as good as Audioquest, QC issues can occur. That potential needs to be eliminated before you drive yourself crazy with a bunch of trouble shooting when a defective cable is the cause. Don't give up on those cables just yet. I previously owned Colorado which I believe Earth replaced. I never heard the effect you are describing here. They were very even handed and did not call attention to themselves IME. Good luck.

I spoke w/Allister @ Audioquest
I consider him rude & patronising

Sheila...sorry you had a bad experience with Allister. He is normally a really good guy. I've had several dealings with him and he was always very helpful and polite.

I have Earth interconnects in XLR and RCA configurations. Not a single problem. Very happy with them.

I love AQ cables, but if that's how he was, make sure he can say the same about you. I'm pretty sure I know who you are talking about. He has an English, if I remember correctly.
