Looks like Little Dot have got themselves a batch of faulty switches or sockets or whatever. What they ought to do, at least where return postage is going to be hefty, is refund the cost of a local technician fixing the thing, provided it's within reason (looks like it could be something very simple). Not likely though, and I don't think it's covered by PayPal since it hasn't actually been lost and the seller will be prepared to fix it. Tricky one, which I think we'll all be interested in the outcome of. I just bought a Muse dac/amp, which so far is going fine, but I think if it developed a fault I'd bite the bullet and have it seen to by someone local. Not fair, I know, but that's the risk of buying from thousands of miles away.
