RE: RMAA
I disagree. First of all RMAA is more flexible 🙂 because we have the open source codes for measures, so you can do whatever you want with the programming.
Second - they use 1 kHz tone in the measurements of THD, then you can adjust the level - if you want it different then -3dB below FS, and get the FFT spectrum. Well, there is nothing to argue about, everyone prefer what he likes more.

a) off topic
b) before you do statements like that, please try spectralab.
c) i would be happy with open source that gives me same versatility like spectralab, but did not find until now

I remember that a member here wrote about a linux spectrum analyser
maybe you'll find some sources this way

b) I did, as well as WinMLS and EFT5.

RE: measures
I forget to add - here is the test description:

and here - are the sources for the measurements:

I want to try another section between the reciver and the DACs digital input. I want follow Jim W.s suggestion and use a isolational amp. Also i want get rid of the 74xxx chip.
would this work, or is a single ended inverter with higher ouput impedance ok here?
