My experience has been in order to get speakers to sound less bass forward/brighter to move them away from the walls. To increase bass/less bright move them closer to the walls. In order to have speakers to become clearer and more focused use an isolation platform like Isocousitics. I couldn't recommend a sure way for a cable to provide the results you want.
Cables to settle brightness
Any suggestions on a cable brand for interconnects and power cables to settle down some brightness?
I have Wireworld at the moment which I might send back.
As I move up the food chain in my system it is getting higher resolving but the treble has gotten a bit forward for me.
I added a PS Audio PowerPlant which is greatly improved the SQ, but now the treble is a little too much. Now it might settle down with burn in, but I’m not sure.
Any suggestions?
