One of the few reasons I know for directionality of a cable is if they only ground the wire internally at one end. They mark the direction so that you put the correct ground in place.

If the cable contains multiple conductors (signal & ground) and a shield, the shield is connected to ground on the sending end only. On the receiving end, shield remains open with no connection. Arrows will point in the direction of signal flow toward the receiving component.
With coax type cable, I have no idea why there would be any directionally,
other than audio fashion. Company ABC adds arrows to their cables
because Company XYZ has them.
I doubt that I could actually ever hear the difference. I have some cables with a small band or label at one end. Is there a general industry standard as to whether the banded end is the source or the destination? Or, does it vary according to supplier, as some responders have suggested?
(I do have some "arrowed" cables and the supplier of these told me that the arrow indicates the direction of the flow. They also told me that at one end the sheild is grounded, but not at the other end.)
In all cases, I am talking about RCA cables rather than XLR.

Arrows will point in the direction of signal flow toward the receiving component.not sure that is true. I believe that some folks believe that all grounding should be oriented toward one component, which, it seems to me is most logically, the pre-amp. However, I doubt that there is any universally accepted standard, so I think that if the OP thinks that it's important, he or she should ask the cable manufacturer.
Tls49, interesting. I'm not one to buy into the b.s.; call me skeptical but... When I had a horrible ground loop hum, I was switching everything around to try to get rid of it and accidently hooked up a pair of audioquest diamond back rca's up in the wrong direction. It actually made the ground loop hum quieter this way. Go figure.
All wire is directional to some degree. Solid core wire being the most directional.
Is there any writing on the cables as well as the bands?
If there is writing on the cables the flow from the source to the amp is usually in the same direction as reading the writing on the cable.

If the cables are new you will need to break them in first.
After break in try reversing the cables and listen to them reversed for a while.
Stick with what ever sounds best to you. Just make sure both ICs are installed in the same direction.
B_limo, I worked in the audio industry for 20 years, and this is what I learned from manufacturers and several technicians. The explanations were always the same. In doing a little research, I did discover another reason that I had forgotten. This is in the second link below.

As far as the experience you had, I think you nailed it, go figure.
