If you always ground at the source end, it’s easy to maintain star grounding. That helps avoid noise and hum by keeping all grounds at the same potential.
The problem with connecting the shield to the source end is that if a source has no ground connection, you will end up with an ungrounded shield.Almost all components today have a separate ground. If not, you can always run a wire from the chassis to ground.

Many turntables and tonearms are like that, especially vintage ones - think two-prong plugs.The typical pickup arm/phono cartridge assembly has a separate ground wire - it’s a balanced circuit with a separate ground intended to be connected to the preamplifier. Again, that helps maintain star grounding.
