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) sorry about thattill said: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
b) I did, as well as WinMLS and EFT5.
c) you've found it - http://forum.rightmark.org/topic.cgi?id=4:480
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?
