Nothing to do with computer engineering or audio though.
Hmmmm,
For folks that are limited to non-ECC RAM, one noteworthy outcome was that I REALLY like the sound of this RAM from ATP Electronics. Very natural and organic sounding, I literally felt tension release from my head and shoulders when I swapped to it.
To me it looks like ECC RAM provides better audio, and if you pick the rigth one (even if not ECC), you get a very organic sounding.
I find this statement interesting, because according to what I know I either modify the quality of an analog signal by directly influencing this signal, or by changing the digital data before it enters the DAC. If i want to change the analog one I need to work in the same frequency band (10Hz to maybe 20KHz) of the sound and not in the range of the RAM frequency (3000 MHz and more).
If I modify the digital data, but don't do this in the correct way (signal decoding, signal recalculation, signal re encoding), I end with garbage. On top by ,modifying the content of the RAM of a computer in a random way, I do not only modify the small piece of data called "audio file" but everything else, including the running programs. The result of doing this is resulting in a blue screen and not in an organic sounding music.
I bought a 1TB Samsung 980 Pro SSD (m.2 pcie) and adding it to my server did bad, filthy, naughty things to SQ. Especially when I had it internally, but even when attached externally via USB adapter. So bad it makes me very curious about how the Extreme and other servers have managed to neutralize the impact.
And that is another nice piece of information. I have my network streamer attached to a Cambridge Audio CXA61 and the speakers shown
here . Not the worst combo and I can e.g. clearly hear that some older resampled albums a renoisy, actually so noisy that I first thought the high tone speakers were damaged when playing them, and I had to test some other sounds to confirm it is the audio data and not the speaker.
I also own a bunch of standard hard drives ranging from 1 to 12 TB, and on the SSD side I have: 840 EVO, 850 EVO, 860 EVO (all in 2.5") and on top the 980 pro (2TB) and the 970 pro (1TB). I used most of them (because testing on your own is better than believing others), attached them internally, externally, locally, to a server connected via WiFi (using two different access points and 2.4 GHz and 5 GHz) and ethernet, used maybe 5-6 different USB cables and at least the same amount of PSU variations. The sound was/is identical - no matter what I did.
So I must be deaf enough on the one side not to spot the quality changes when changing the hardware while hearing the quality differences in different albums being played (all in lossless/ flac with at least 16/44 quality).
I am surprised
