Many people lacking experience with high-end turntables propagate this myth because that’s what they’ve heard or read.
This is one of those myths that’s been perpetuated by the hi-fi press and those who buy into the pseudo-science that also says VTA and anti-skating don’t matter. The reality is that there are stunning belt-drive and direct-drive turntables, and some real clankers of each type too.
It’s ultimately not the drive method alone that determines system performance. Honestly, most people aren’t interested in the technical details though, nor have they been exposed to the range of equipment necessary to form a really valid opinion. Some of us have though. How many record store guys do you think have listened to an SP-10 or L-07D for example, let alone owned these grail machines..?
