For fun you might want to see how much of a difference you can hear using the interconnects without any batteries.
My understanding is the batteries are more theoretical than actual.
Batteries in my Audioquest Colorado RCA interconnects
The box attached to the cables read: aq DBS 72v
It takes (6) 23ae 12v batteries in each box per cable. I judiciously replace batteries in remotes etc. yearly like checking the fire alarms. These batteries, which I have failed to register, have been in / attached to these cables for 8 years plus however long they were in prior to my purchase. AND they did not leak. AND when I push the little button on the box on the cable the little green light turns on.
Would that be pure lucky and amazing?
Also, can anyone tell me if I am using them in the best way: They connect the output of the tube pre-amp to the input of the tube main amp. My thinking is that is where the most current / possible noise would exist. But looking for advice. As these are my most expensive (I think best quality) interconnects I own.
