need recommendation on high bandwidth cable

i am looking for interconnect cable which will deliver high bandwidth. i am struggling with the fast cable with no bass and foundation

Most high end audio cables are good for bandwidth. The problem is the source that is driving them. If the output impedance is high, the capacitance of the cable can roll off the highs. So if you want your cable to have bandwidth, the source driving it has to have a low output impedance.
