the specification page i provided was of the Hypex DAC module only.
But the Fusion manual states the exact same figures for the whole thing

Hypex are very transparent about their products . but you made it as if I'm not doing an apples to apple comparison but I actually was.
So actually, it doesn't really matter that the DAC is just 100 or 110 SINAD.
True that I was not totally precise with my comments. Sorry for that! Yeah, I can hear a hiss with my 109dB/2.83V sensitive tweeter when connected directly to the Fusionamp, but only hearable when the room is quiet, and no music or any other sound comes from the speakers, only just turned on the system. But since I padded down the tweeter by 11dB with a speaker level L-pad, the audible hiss has gone.my MiniDSP 2*4 HD has a S/N of ~107 dB and I can hear the hiss loud and clear at night.
these noise levels (assuming they will be amplified further by the amplifiers) are audible and frankly annoying. This is not yet the extreme insignficant case that you're making it out to be.
That's far from true tbh.
I would pick the higher harmonic distortion, because the loudspeaker drivers usually three order of magnitude worse in this regard. So in theory, the harmonic distortion of the amp (plus DAC, plus whatever) would be masked by the distortion of the loudspeaker anyway. Or not?Agreed. I already mentioned that the SNR of the amp is two orders of magnitude better than the DAC. Distortion is however one order of magnitude worse. Pick your battles I guess.

I found in my room that replacing the supplied power supply with an ancient one from a ZIP drive (remember those?) made minidsp quieter. I also had noise issues when usb from a computer connected, that was helped with clamp on ferrites. Not sure you get 107db including these noise contributions from cables, I think it’s typically higher noise.my MiniDSP 2*4 HD has a S/N of ~107 dB and I can hear the hiss loud and clear at night

Hello, do you have any specific information on when the new DSP will be available for sale? Will it be possible to exchange an existing unit for a new one?There will be a new version in the near future. DSP has been upgraded from adau1450 to 1452. A larger pic controller was needed because there was no space left. And yes, Fir's on the input and output channels.
Good question! That post is almost 2 1/2 years old now.. where is the actual product? Starts to sound like Duke Nukem Forever... At least that came out eventuallyHello, do you have any specific information on when the new DSP will be available for sale? Will it be possible to exchange an existing unit for a new one?
Bummer One would think that sourcing adau1452 would be just as hard as adau1450? The price difference is negligible, so just switchWith the ongoing parts and coronacrisis it is impossible to introduce new product's. It is a pain in the ass to keep up production for existing customers.
That's the whole point, what does it then matter if you change one part At least you can make customers happy, even if they can't buy your new product (yet). At least it exists . It will prevent (some of) them from looking elsewhere.It's not about a specific part but all parts, shortages in resistors, cap's, powerfets and so on. All manufactures are having these problems.
Anywhere People get creative...Looking where?
Not for FIR DSP's.Good point. They’re already on top of the hill.
