RMAA result are inaccurate???
I think you are insulting RMAA designers, honestly. Read this from them:
|As we can see, the results in Noise level and Dynamic range have just a 1.3-1.5dB difference (1 percent). We deem our precision quite appropriate considering that the use of professional equipment costs tens of thousands of US dollars while our expenses have been minimal (in the case of RMMA). Certainly, you won't receive passport data the same way, but one can be quite able to check the announced figures. Thus, we had the same picture with LynxTwo and the difference between passport parameters was about 1 percent. The test also enables to reveal if there are any quality problems in different modes.
Pardon me, they are comparing with Audio Precision System Two equipment.
[sarcasm]I guess your ears is more accurate than those equipments and they should invite you to come to their lab using your ears as a reference design of their next version of RMAA. Oh no, hearing test is subjective, many more people will question the RMAA accuracy then.[/sarcasm]
Sorry if I sound to be harsh. I am not doubting your listening experience, however, as I said before, listening is subjective to individual preference. So said, while I respect your opinion based on your listening experience, please do yourself a favour and respect those designer's works as well.
And regarding the RCA output impedence, what is the measurement of individual soundcard? How much the difference is?
