Singxer SU-6 + RME ADi2 DAC FS V3

The singxer is not really a class A amp. If you really push the amp it will switch to AB. (Not that it makes a difference).

I also use the singxer SA1 and a SMSL SP400 (thx amp) and there is zero difference in soundquality.
Yes, I also read somewhere on the Internet about the switch from class A to class AB. It's quite possible. The components in the Singxer SA-1 need to warm up to their operating temperature first, I'd say it takes about 30 minutes. Then a completely honey-creamy warm sound flows from the amplifier, somewhat compared to tube amplifiers. The metal chassis can then be around 50°C.
There are a lot of good reviews for the Aune S17 Pro. It should be purely in class A and is said to heat up to somewhere around 70°C. But this can be helped by placing the amplifier on anti-vibration pads and thereby achieving better cooling. This is simply the fate of class A amplifiers, their components get very hot. It is said to be even better than the Singxer SA-1, which by the way came out after minor modifications in the second v2 revision.
 
Hello,
yes, everything is well explained and shown in that video. How GoldenSound measures jitter and electrical noise.
He compares optical out of a random PC VS Optical out of a DDC. Residual noise is measured regarding the role of USB Isolator. These have absolutely nothing to do with what we are mentioning here.

As far as he comes by comparing DDC each others, this is absolutely nothing significant (can be observed with common run-to-run variations while measuring something), and an universe away to be any kind of audible :

Not a great compliment i would say... And not what SA-1 measurements tell.
It does not have to be. 100 people/100 tastes. But for me, the resulting sound together with the HiFiMAN Arya Stealth headphones is more pleasant than from the 6.3mm headphone output on the RME. This is also the reason why a lot of other people, users connect an additional amplifier to the DAC or DAC/AMP. To change or suppress the resulting sound. It's up to everyone to decide.

An amp can't "suppress" the resulting sound. That's pure nonsense. All it can do is adding coloration (to a very variable extent) by amplifying it.

Anyway,

@666jopo666, if I may, before I unwatch this thread : since it seems that none of the answers you got here suit what you wanted to hear, what was exactly the point of asking us... anything ?

As you repeat over and over : "It's up to everyone to decide". "100 people/100 tastes". Alright, then. So... Why would you need our thoughts, to begin with ?

No- this is where audiophilia and upgradaholics (second being my term) is wrong and partly why this site exists.

If there was an actual audible change resulting from these gear swaps and upgrades then people might have a valid point (but why not use EQ to achieve a similar result with initial good gear like the RME if so?).

But the simple face fact is the majority of these "changes" are imaginary or resulting from less than ideal testing/ comparisons.

The DDC will do nothing to the sound
The separate amp will do nothing to the sound given it is transparent if the RME can amplify adequately (and for the Arya it absolutely can) .

Post whatever opinions you like but be prepared to receive pushback. You have (depending on how much you paid) nearly $1000 of kit that serves no audible purpose.
 
I tried both variants and the connection of active monitors and HiFiMAN Arya Stealth headphones is much better via the Singxer SA-1 than via the RME. Singxer SA-1 has 0.66µV @ Niveau de sortie max, SNR / DNR 147dB. It has an absolutely black background. It really is a better headphone amp than the RME ADI-2 DAC. Tested for several months on my own ears.
:facepalm:

SA1 50 degrees Celsius? lol ? I run mine in high gain and pretty loud as well with planar headphones. It gets maybe a bit warm if you touch it. But this thing is not even close to 35 degrees after multiple hours .

There is nothing I would say sounds creamy.

Yes, the amplifier will add a different timbre to the sound. That's exactly what the difference is between the output from the RME and the SA-1.
I didn't even originally want to address the amp in this thread, but the discussion has drifted to that. Anyway, my questions were written in the very first post. And the questions were more focused on the person who also owns these devices (SU-6 and RME), than the person who did not have the SU-6 connected to the RME.

1) Is it necessary to have the SU-6 driver installed?
2) and 3) What specific protocol is best for connection between SU-6 and RME?
4) If there is anyone here on ASR who has a SU-6 connected to a DAC via I2S, I wanted to know their opinions.
5) You answered me that it doesn't matter what device I stream from. My understanding is that a PC is essentially the same as a pure streamer.

Otherwise, I keep the SU-6 plugged in. I just hear the differences there. So either I'm already completely deaf or psychoacoustics is a powerful witch :)

Anyway, thank you for your answers and observations.

Not if it's a good amplifier. And the SA1 is a good amplifier.

The metal chassis is heated, I didn't measure it with a thermometer, but I'd say it's quite a bit hotter than the rest of the components.
I would characterize the sound os SA-1 as very very clean and quiet (almost "dead silent"), smooth and warm like a creamy caress, detailed with a large amount of space and a rich soundscape, nice separation of individual musical instruments. That's how I feel when listening to music.
 
It does not have to be. 100 people/100 tastes.
But in this case if the 100 people would be put into controlled test situation they couldn't' hear what they thought they heard.

That is because the devices produce so close the same result that it's impossible for a human (or a bat) to hear a difference. If you do, then it's in your head.

There is nothing wrong of course buying stuff as it most definitely can provide more pleasant experience, we are all humans after all, but it's your imagination that causes the effect.
