I use two of these at my studio to link rack units
Been using two of these units at my studio for 3 years now.
I actually gave it a 5-star review some time ago, but I recently found it adds noticeable distortion to the signal being patched through.
I did a pretty simple measurement always using the same patch cable, a sine wave generator in my DAW, and listening and checking the input signal with an FFT frequency analyzer.
My results:
1-When measuring directly from AD to DA I got a pristine clean signal.
2-When patching the signal through the NYS I got a lot of added harmonics.
3-This happened independently of sine wave frequency (tested from 20 to 20kHz)
4-Distortion only happened when the signal output was above -19dBfs
5-As the output volume increases the distortion changes, as in the harmonics are not the same as the signal get's stronger.
6-This is happening on all channels.
I don't know if it always distorted the signal or if it just didn't age well, but my studio is a dry smokeless place so either way if after 3 years it's malfunctioning it means low quality.
In conclusion, don't waste you money on this unit!

Seems good at first
I used this for almost three years, thinking it was OK and unnoticeable in my signal chain. Here and then there was a signal dropout that was corrected by reconnecting cables to the unit, but I didn't think much of it.
That was until I rearrenged some of the hardware here and got a 500 series housing with a linear (instead of a switching) power supply. Then suddenly both stereo compressors routed into the NYS-SPP started behaving super oddly (one went mono unless on bypass, the other lost 6db on one channel -if- on bypass).
A quick test connecting directly into the interface revealed both comps were perfect. Repatching to other channels in the NYS-SPP resulted in the same outcome. The last test, running mixes through it, caused both my compressors to sound weirdly gritty and aggressive in the high-mids, but while connected directly to the interface both of them sounded cleaner too.
This is a poorly built unit, my replacement (costing three times as much) is on its way. It does add distortion depending on the level and complexity of what is being routed, and therefore I cannot imagine that it wouldn't affect quieter signals too even though this is way less noticeable. Better not skimp here (by having a unit like this handling all your signals).

Very flimsy build quality. The connections have started to loosen after limited use, leading to partial signal loss on some channels.
