Disappointing, but not unexpected considering the price.
A real audiophile should perhaps consider the Nanodigi 2x8 surrounded by high quality devices ( USB>S/PDIF converter, DACs) and perform SRC in the player of the PC ( assuming the PC has the guts).

It would be great to see a 2x4 HD with higher quality DACs. I am sure people would pay more for such a device.

From graph there's nothing in the audible range, paying more, or more db down won't change the fact that there's nothing to be hear.

The only problem with mini-DSP is that they do not propose any device with digital input, multiple digital output and FIR filters for use with external audiophile DAC or digital amplifiers.
A 2x4HD with digital outputs or an OpenDRC DA-8 with digital outputs would have been great...but it simply doesn't exist.

Are you sure you REALLY need FIR filters?
Otherwise, the Nanodigit would do the job.

Yes absolutly sure. FIR filters are the only means to perfectly shape magnitude and phase as needed and replace IIR crossover and EQ with many benefit.

I read the following indipendent comment about those measurements:

"The judgment is excellent.
The conversion jitter (at least taking into consideration the level of symmetrical sidebands, which is about -127dB from the fundamental) is contained, very limited.
We are on values around 23/24 picoseconds on sampling frequency of 48khz.
The residual, very low even that, random (not symmetrical to the side bands) is caused by the noise of power supply"

In other words, as stated by Patate91, there is no noise or jitter that can be heard at those levels even by the most discriminating listener.
Nice job!!
