George - very good write-up. As usual for you!!
As for what people feel about Hidizs nowadays, let's just say the AP80 is my first and last Hidizs product. I personally, will never buy Hidizs again. And that is a shame, since the AP80 is not bad at all.
I am done with Hidizs as a company.
For context, I own several entry level DAPs from FiiO, HiBy and Shanling. All Chinese companies. All offer good value. All (other than Hidizs) provide good support and try to deliver on their promises.
Hidizs on the other hand promised A LOT during the crowd funding campaign, delivered NONE of the promises, have NOT updated the firmware in months (and there is a list of known bugs), and gone totally silent! At least on Head-Fi.
Conclusion:
If you're reading this post, you're probably looking for entry level DAP. My advice to you: buy FiiO, HiBy or Shanling! All 3 companies would make you happier!
Did I answer your question George?
