Why does my DAC sound so much better after upgrading digital SPDIF cable?


I like my Mps5 playback designs sacd/CD player but also use it as a DAC so that I can use my OPPO as a transport to play 24-96 and other high res files I burn to dvd-audio discs.

I was using a nordost silver shadow digital spdif cable between the transport and my dac as I felt it was more transparent and better treble than a higher priced audioquest digital cable a dealer had me audition.

I recently received the Synergistic Research Galileo new SX UEF digital cable.  Immediately I recognized that i was hearing far better bass, soundstage, and instrument separation than I had ever heard with high res files (non sacd),

While I am obviously impressed with this high end digital cable and strongly encourage others to audition it, I am puzzled how the cable transporting digital information to my DAC from my transport makes such a big difference.

The DAC take the digital information and shapes the sound so why should the cable providing it the info be so important. I would think any competently built digital cable would be adequate....I get the cable from the DAC to the preamp and preamp to amp matter but would think the cable to the DAC would be much less important.

I will now experiment to see if using the external transport to send red book CD files to my playback mps5 sounds better than using the transport inside the mps5 itself.

The MPS5 sounds pretty great for ca and awesome with SACD so doubt external transport will be improvement for redhook cds

Or I just haven’t drunken the Kool-Aid.

Kidding aside, I know there are other aspects to speaker wire than gauge and material, but the rest make no audible difference unless specifically designed to (and never an improvement, in terms of more accurate; but it’s rare to get a measured difference, and usually requires an amp with a terrible DF). Speaker Cable Face-Off, I seem to recognize someone’s company’s cable being tested and showing no benefit in skin effect over zip cord, despite this someone’s claims, and that no benefits were found for audible frequencies.

As I’ve already shown that any decent DAC can reduce jitter to at least -110dBFS, I would appreciate one reason why a $2000 USB cable is worth purchasing besides asthetics/build quality.

Anyone making claims of a more open soundstage by exchanging speaker wire should have such claims be taken as truth, as the two have no correlation.

You may have seen Ethan Winer’s recent video where he null tested some different speaker wire (invert polarity so any similarities cancel out), and came to the not so surprising result of having no audible differences. This is nothing new, people have done such experiments for years.

I also own a measurement mic, so it would be pretty easy to see any frequency response deviation, decay differences, etc. by changing out my analog/digital cables and speaker wire. I personally won’t do this though as it most certainly would be a waste of time and money.
mzk,
You speak with such authority. I believe we are all blessed with certain abilities. Yours apparently isn't hearing. Nothing wrong with that, except when you base your hearing ability as the pinnacle & make authoritative statements based on that.

All I’m saying is if your system has jitter that’s -130dBFS, that’s not an audible issue, and you shouldn’t upgrade your cables, DAC, buy a re-clocker, etc. to “fix” it. That’s like complaining that your speakers have a 0.1dB spike at 10kHz.

Spemd money where it matters, the weakest links being your speakers and the room. $10,000 cream of the crop speakers (Revel F228Be for one) and a $350 Onkyo integrated and using analog and digital cables bought at Walmart in a properly treated room will sound better than $3000 cream of the crop speakers (Ascend Acoustics Sierra Tower with RAAL for one) paired with a $10,600 Cord Dave DAC, $54,000 Boulder 2110 preamp, $99,000 Boulder 2150 monoblocks, and all Nordst Odin2 cabling ($30,000 for 1 meter of speaker cable, $20,000 for 2ft of digital interconnect, etc.), in a less than properly treated room.
mzk,
Please, please, please tell us you've heard these 2 systems in the same listening environment to come to that conclusion. If not, it is pure speculation (stated with authority) again.
@boxer12

Prove me wrong then; you state they do with no proof so far, yet I have shown proof, and it shows the audible differences can be treated as minimal to non-existent. I’ve never seen the Sun in person without Rayleigh scattering, but I know it will look white instead of the normal yellow/orange. 
 

So no then? Doesn't seem very proper for someone who rests on science. No double blind tests, no peer reviews, no measurements. Really it's just an uneducated authoritarian opinion. I've never heard any of that equipment so will not comment on which is better. If you supply the equipment I'd be delighted to run the comparison though.

Don’t need double blind tests when measurements exists, and those measurements are well below human audibility, which is found via scientific blind testing.

This is an illogical circular argument, a.k.a. "begging the question." Either you believe double-blind testing is valid for establishing audio differences, or you don't. You can't have it both ways.
@cleeds

Please re-read what I said. I believe in double-blind tests, but they are not needed to compare DACs when measurements exists and such tests have been done to analyze the thresholds or human hearing.

It’s like how I don’t need to race a Tesla Model S against a Toyota Camry to find which is faster, there are recordings of their 0-60 and 1/4 mile performances.
A common misconception is that blind tests are proof of anything. Another common misconception is that measurements are proof of anything. They are both effective marketing ploys, however. You know, like, “measures flat 25 to 20 kHz +- 2 dB.” Or, “THD below 0.000%.” And, “blind tests will prove that aftermarket fuses are a hoax.” 😬

Understood! You believe in double-blind tests sometimes, but other times your faith convinces you that they're not needed.

" It’s like how I don’t need to race a Tesla Model S against a Toyota Camry to find which is faster, there are recordings of their 0-60 and 1/4 mile performances"

Measurements are not all inclusive... Even with that one measurement, the camry still sounds better :-)
