wait, this can't be true.
someone here is hinting that it would preferable the use of cheaper connectors on the front panel of a (very high) quality audio interface because some crappy quarter inch plugs get stuck in it?
why? so that the same users could be writing back again, one or two years later, shouting at RME that quarter inch connectors have loose contacts that lead to electrical noises and glitches only after two years?
there's no better choice than Neutrik, when it comes to electrical and mechanical stability in the long term.
if space is at a premium (and on a 1RU device, it is), combos are the only possible choice for a front panel where the end user wants to stick a quarter inch plug.
ok, plugs are not all created equal. some learn it earlier, some learn it later. understanding it shall not require a master degree in rocket science, though: just the price difference between the real ones (used by pros) and the cheap ones (used by non pros) shall suggest which one's worth buying, and which one's best left on the store shelves. an interface priced around 2.000 € can't go hand in hand with a 5 € cable, it's like using black paint instead of china ink for a 2.000 € Montblanc fountain pen and crying it clogged the tip.
blaming RME for having made a wise, long-term-inspired choice just because someone can't pull out a cheap plug off a UFX, sounds downright silly to my ears.
blame the cable manufacturer for not writing on the plastic wrap "don't use on quality appliances if equipped with quality connectors - risk of getting stuck", but please don't blame RME, and don't blame Neutrik, either, as both try hard to do it right for those who might buy it just once, but want it working flawlessly once for all.
