I had an unfortunate experience with iBasso. I bought their AMP8MK2S and when it arrived (after a long delay by DHL which iBasso handled well), I tried to install it and it wouldn’t fit properly in the socket. I emailed them and said I was worried about the fit, they told me it was normal and to just push it in and fasten it with the screws, which I did.
It sounded great for a while, then I started getting audio cutouts and the sound would start to get hazy until I took it out and reinstalled it. I contacted them again and told them I was seriously worried about the device, and they basically told me I was imagining things. I tested it again, tried the stock AMP which also had audio cutouts now, and emailed them again asking to send it back. They instead sent me a new AMP8 module that worked well for about a week, and now it’s experiencing the same issues. I asked them if I could finally send it back and they said I could, but only if I paid a heavy international shipping fee.
It’s just disappointing since I really do love this device and they not only convinced me to break it, but they pretended like I was lying about it and won’t even pay the shipping costs to check. At this point I’m just gonna get a DAP from another company, I don’t like FiiO models as much but I’ve had to do their repair process before and it was a much more respectful and professional experience than what iBasso offers their customers.
