Longer is better?

No “the Office” jokes here!  Ok literally had a retailer tell me I should want a longer digital cable (USB to be specific) vs a shorter one. That even if you had to coil the cable it would provide better sound. A shorter cable worsens the sound, per this guy. So . . . Never heard anything close to this anywhere. Goes against any understanding of physics or general audiophile learning I’ve accumulated. What say you?  Is this guy a sleezball salesman (because we all know longer cables cost more!) or am I missing some sort of mystic voodoo?

Get the length you need but 1m minimum it’s more for practical reasons. I like 1.5m cables as it allows me to move things around if I need

There is unlikely to be a difference. But theoretically really short ~ 6” can cause reflections… but unlikely. 3’ is great to give you flexibility. It is the speaker amp connection that is really good short.

Can’t say for sure but some very knowledgeable folks here in the past as well once asserted short digital wires are more prone to reflections than longer ones.  I respected those folks technical acumen enough to always lean a bit longer when in doubt.
