Those spikes are the test signals! They are supposed to be there!
The Intermod test signal is a 60Hz and 7k pair at -5dB and -17dB
respectively
there are some nasty spikes out there

You can ignore the spikes - they are an artifact of the RMAA software

You want to see the signal path BEFORE it gets onto a CD/vinyl...it
ain't what you'd call minimal...

Here is a similar test using RMAA on a Touch with a 16/44.1 RMAA
generated test tone file...
Note that whilst the Touch is slightly noisier than the TP (but not in
a way you can actually hear!) it has less distortion. This is probably
showing the difference of the TP PSU vs the Touch and the

Interesting. The spikes are quite clearly a 60Hz fundamental plus
harmonics. My initial assumption was that it is some kind of mains
frequency breakthrough.
But you say it's to do with the software,

I agree. It behaved oddly. That 60hz noise may be causing issues.
I plan to run it on balanced. But I need to pickup a cable.
Cool.

I'm interested in a 16/44 signal, personally.

It was 16/44. It's in the Report.
I will run 24/44 as well.

Do you mean Sampling mode: 16-bit, 44 kHz? I assumed this was the ADC
mode, not the digital signal that is input.
