Recently I learned that a certain Chinese manufacturer has released a new headphone amplifier: F.AUDIO AM01.
The link for this product in Massdrop is: https://drop.com/buy/f-audio-am01-headphone-amp
From the information I have received so far, this is an inferior imitation of SMSL SP200
A friend of mine got a unit and disassembled it. (Unfortunately, my AP is not there, otherwise I will be eager to measure it)
In my opinion, this is the result of twisting the amplification part of SP200 by 90 degrees.:
A simple review from my friend:The workmanship of the shell is very poor, soft and can be pressed, the gap is wide.
The most important point is that he can clearly hear the noise floor when using IEM and XLR input!
Of course, none of this is supported by measurement data. When my 555 comes back, I will get this product for measurement as soon as possible.
