I would like to thank you for pointing me to the manufacturer response.
It is another proof of how vague , wrong and deliberately controlled is the ASR website.
Quoting from the manufacturers answer where he proves with detailed measurements the following
"
So, to sum up, Rhodium:
- can output 1 Vrms into a 32 Ohm load
- will generate 3 mW into a 300 Ohm load, and 30+ mW into a 32 Ohm load
- will have < 0.008% THD @ 1 kHz @ 30 mW output (1Vrms into 32 Ohms)
- has even better performance at typical 1 mW output listening levels
- was designed so that tradeoffs benefitted typical listening levels rather than rarely-used full output levels
- is not optimal for high impedance, large/inefficient cans
- is extremely portable
Oh, lastly: we use the ALC5686, not the 4050 as shown in a previous picture. It's a bigger package (6mm x 6.5mm) but with finer pitched pins. We also have a higher tolerance oscillator, and selected every cap in the system with an eye towards superior performance in the small package, but when tradeoffs arose we chose to give priority to typical listening levels (-25 dBFS to -10 dBFS) rather than full/max output (0 dBFS).
I hope this is instructive; for anyone wanting additional tests or information about our APx setup, please feel free to ask.
