This is why I can’t understand people bashing the brand...
Who cares? Some criticism is justified, some isn't. As a thinking adult it's your job to consider the arguments and decide for yourself where the truth lies. Other people do many things I cannot understand but, that's other people for you ;0)
Is criticism of the bending plinths justified? Well, yeah, I think so. It is an actual problem, it has happened and I think there is a reasonably argument for saying that it shouldn't.
Yes, I agree with you that Rega are brilliant and will sort it out but that's missing a whole bunch of points. If the deck is a few years old the owner could be forgiven for not realizing that Rega will still take an interests in resolving his problems. He might anticipate a hefty bill or think it cannot be fixed. There will be a raft of question marks and worries in an owners mind over a situation like this.
Depending on his location, it may not be too easy to get to a Rega dealer and it's time and aggravation he might not appreciate. If he has to post the deck, does he still have the correct packing and even if he does, posting a turntable is always a risk.
Rega turntables are inherently well built and reliable but from what I can see absolutely every manufacturer drops the ball sometimes. I'm sure they will do everything they can to sort out these issues when they occur but that doesn't mean we should pretend they don't exist. Good as they are, this is still Regas fault.
