They answer me whenever I write to them and claim they'll be returning. The AP100 was a stupendous entry into the marketplace and I couldn't wait for the follow up, but they mysteriously adopted radio silence... implying that their social media team changed or was disbanded. I hope their new model still happens as they told me many were hard at work on it.
Ah yes the AP300 I believe it is going to be called. I haven't seen much about it but I guess it's supposed to be touch screen maybe andriod based like the Fiio X7. Well I hope they do come back. it's nice to have the presence of a company like Hidizs right here on the forums like Fiio does on their product forums.
