It is obvious that a disk cannot have a different rendering but here it is certainly the connectors or the path that even to the Dac that poses a problem
Observation made by 3 people.
I’d hope so.
It’s quite amazing though, how the OP went waah-waah crying to the moderators when pointed out that he’s wrong about hard drive connections… And the other one wants to both have it that blind testing is not important and it is his “perception” that counts and, at the same time, proposes some hare-brained quasi-technical explanations for the alleged difference. Can’t have it both ways, but cognitive dissonance is a powerful thing.
Nopes. After being read, decoded and buffered they go through the same path to the DAC.
Just go to the Support section of this very forum and see many people discussing how a certain fiber cable, not even anywhere near the analog path, makes “day and night, wife heard from the kitchen veil-lifting” difference. Sorry, but your sighted biased comparisons have absolutely zero worth in regard to the sound, and would be of interest only to psychologists studying mass delusions.

Once again don’t take the cable bias by taking people for idiots
You repeat yourself and you push
We will not agree on this point. End of discussion for me.
Yes, Boris!!!
Because I couldn’t believe it at first either. But I asked my wife to cover the display of the 520 so that I couldn’t see what was playing. The same with the Macbook. I only had the woman on my lap (where I usually am 
) and she was sitting in another corner of the room. I came in, sat down on my listening spot and she started. At that moment, I didn’t hear any difference because I had no control. It was a little confusing not having the control to imagine something.
Besides, if there are differences, they are so marginal that I don’t care. What’s more, how my ears pick up something also depends on the time of day and it has been scientifically proven that due to changing air pressure, loud surroundings e.g. at work, possible high blood pressure or even lack of sleep, the ears don’t always work at the peak performance appropriate to their age.
Do not forget the beer, or any other alcohol. Alcohol is making strong equalizing perception, lowering ear sensitivity to high mid frequencies 
There is no difference. Unfortunately you seem to have some problems with reading comprehension, but that’s on you.
Yup. This wasn’t quite a scientific test, but much closer than the sighted nonsense some people in this thread demand that we believe.

I was drunk on the 13th. But no scotch.
I had a good Russian vodka that knocked my legs out from under me afterwards.

Hello,
I share my experience here. I added an internal SSD to my RS130 to limit the number of cables and boxes. I didn’t expect anything else. Since then I found the sound a little more aggressive in the treble. I recently put the external drive back and the harshness has disappeared. I looked for a reason for this observation and I came across this topic.
Too bad this topic has been polluted by a controversy. I understand those who can’t admit that you can’t hear a difference between 2 types of HDD connection. It reminds me of the controversies about cables. I myself took for a madman a salesman who made me try a new amp and explained to me that it didn’t sound good because of the cables. I have since reviewed my Cartesian position on cables following numerous cable tests and I do not think it is psychoacoustics because it happened to me several times to buy very expensive cables and to have to admit that they sounded less good than the lower-end cables that were installed before (with a significant loss of money). Even if I cannot explain why there is a difference between 2 cables or 2 types of HDD connection, I hear it and allow myself to share my observation without trying to convince. I would like those who do not hear a difference to respect this observation and not try to explain to me that I am wrong because it is not technically possible. Yes it is not technically understandable that 2 types of USB connection sound different but several of us have made the observation. Audio often confronts us with incomprehensible mysteries, that is what makes its charm a little. Coming back to the RS130, it’s a shame that the internal SSD doesn’t sound as good because it was still simpler.
Hi @Jermi37 , some time ago, I also had the opportunity to listen to the internal SSD storage on my RS150B. I didn’t notice a significant difference between the external USB drive and the internal SSD. It seems the music plays exactly the same. Furthermore, it sounds identical when streaming from the Qobuz service or files purchased from Qobuz. The difference I noticed, and can identify with my eyes closed 100% of the time, is when playing via DLNA using Elmedia Video Player, thus, the same files on my MacBook and streaming DLNA to my RS150B play slightly better…
I’d recommend doing the following: Play music from your internal SSD with your eyes closed or turned away from your system. Ask someone to switch between the external and internal storage with the same files. Try to identify the difference. Be honest with yourself—if you hear a difference, then there truly is one. If not, it’s likely psychoacoustics at play.
Regards, Vik.
In other words, as usual there was no difference whatsoever (because there could not be) but a proper audiophile would much rather admit that he is incapable of comprehending a simple test protocol than admitting that he is as susceptible to the “psycho” side of psychoacoustics as anyone.
Except that is is wrong, but you will be chasing fairies forever, unless you learn how to a) test properly and b) set up your system to sound good in your room. SOmething achieved not with cables at all.
Thousands of people smeared green marker on their CDs, too.
Except that it does not. But people who want to believe in fairy dust will believe.
RS130 does not sound at all. Even 150/250/520 which actually do produce sound ,sound the same from an internal drive.
Did you try it? No!
Do you have a Rs150? No!
Do you have a Rs130? No!!
I did not try using a pyramid to sharpen my razor blades either.
No. Larger screen wasn’t important for me at that location.
Of course not. Unlike you, I know how things work and do not waste my effort on things that do not do anything.
Oh well if you know I have nothing more to say
This type of communication reminds me on flat earthers… “Did you see the curve?” “Oh, well I have nothing more to say, Earth is flat”…
Simply, there are some things which are technically impossible. Ok, I do not always agree with @BorisM because there are myriad of scenarios possible, but he is mostly right.
So, @Jermi37, before you blame on hard drive you should try to change the type of connection and DAC to be sure that the effect percieved is not because of DAC, because that is the place where sound originates. If there is a general problem, and if there is a loss of quality if you use internal hard drive, then it must be repetable in all RS130 stremaers. If that is not the case then the problem is somewhere else, not in the RS130 and its hard drive.
It has nothing to do with the Dac!!
Test with internal and external disk = difference (rs150b)
Trial with streaming and internal disc (song bought on Qobuz) = difference
Trial with streaming and external disk = no difference
The best way to talk about it is to have tried, theory is something else
I tried all of that, but I couldn’t detect any difference—neither in a regular test nor in a blind test.
