respected_ent,
Just...use your cables. If they aren't faulty, they will work fine out of the box.
The fewer audiophile myths you fall for, the less money you will waste and the less paranoid you will be.
Best interconnect burn-in method
I think I know the answer to this, but I just wanted to double check with everyone. I am in the process of burning in an XLR interconnect. The interconnect is between the DAC and the integrated amp. I am using a laptop as the source, and it is connecting via USB cable to the DAC. Is it true that I am still burning in the XLR IC if I leave the integrated amp turned off while playing music continuously on my laptop with the DAC turned on? Thank you for your input.
