I bought this to connect a HD500 POD to a DT50 amp. The cable is long enough to place the POD approximately 30cms in front of the DT50 (with the cable plugged into the rear of the amp). Line 6 recommends this cable (not surprisingly) as providing a better signal than a normal XLR cable. I've not tried an XLR cable so can't comment on whether the L6 Link Cable is better than an XLR cable. No issues with the sounds being sent to the amp through this cable.
