A good experience with Apos means nothing regarding the veracity of OPs claim. The Apos response here seems far from optimal. To overcome this, they better make killer gear with awesome sonics.
Caveat Emptor
I almost never post and never have submitted a bad review but my experience with Apos Audio requires me to do such.
I ordered a DAC from them and they sent wrong color. I tried to contact them via phone and the only way to get someone's attention is through email. They gave a slight refund if I wanted to keep the DAC which I accepted. Then when I hooked it up it would not work correctly. They offered suggestions on a possible fix which I tried all to no avail. I asked to send the unit back to get refund and that is when the issue on a 20% restocking fee was communicated to me due to having it longer than the time allowed. This was not acceptable to me as I had to wait for their response between emails. I sent the unit back and filed a dispute with Paypal and it took me 3 weeks from the time they received it to get my money. I will never buy from them again and will give my business to Mother Amazon where returns are much simpler and I don't have to write numerous emails to get refund.
Just a heads up to all.
