It’s only a huge hassle now because most DJs don’t spin vinyl so a special effort has to be made for them. Modern turntables aren’t 1970s tech any more than CDJs are 1980s tech because it has a CPU in it. For starters DJ turntables are direct drive whereas the stuff from the 70s (and, to be fair, most home record players too) are belt drive. The reason vinyl turntables fail less is because there’s less stuff in them…
It’s only a huge hassle now because most DJs don’t spin vinyl so a special effort has to be made for them. If you're standing in front of an empty table before a show at an actual venue with money and stakes on the line, and the hypothetical is posed, "which is more likely to produce a smooth listening experience for our guests tonight?" the answer is always CDJs. The vibrations, the stabilization required, the needl…
You can claim that CDJs are more reliable all you want but I call FUD on your claims of vinyl. Both as a DJ, event organiser and paying punter.
Also your claim about a completely device failure isnt the only failure mode for a CDJ. I’ve seen CDJs fail because the platter has lost its touch sensitivity. I’ve seen their buttons fail. I’ve even seen them overheat in some warehouse parties with inadequate ventilation.
But let me reiterate this: if you’re equipping a venue and you pick vinyl or CDs (or anything for that matter) because of reliability concerns then you are automatically making the wrong choice.
Their reason you shouldn’t pick vinyl has nothing to do with the risk of someone bumping the table. The reason you shouldn’t pick vinyl is simply because that’s not what most DJs will want these days.
You pick the medium based on the performers requirements not some hypothetical disaster scenario. This isn’t software engineering, it’s music performance.
