Thanks for KillerX's post. I have confirmed with him that it is a standard amplifier module damaging problem because his 901 line out is working fine. I do have a feeling it is a stupid problem that can be solved by burn in in factory, but we need to do more research other than burn in. I have called our manufacturing manager 5 min ago and we will check all of our stock standard card and make sure this problem will not happen again. We will check our AD8397 vendor about this problem as well and make sure it is not a chip problem. We are also working on QC procedures so that we can 100% get rid of defective amp cards before shipping. From now on we will buring in all amplfier modules for 48 hrs before shipping.
Because we can not ship standard card at this short period time, all customers who currently have pending 901 with standard card order will get IEM cards to replace standard card.
