In the end, since I found no answer in the comparison with Shiit Jotunheim , i could not resist and i decided to buy the Topping A90.
It arrived 2 days ago.
I connected it to the Chord Qutest connected to the PC with USB and I can confirm that there are no noises of any kind at any volume in the balanced XLR and 4.4 outputs and not even in the single ended output.
So I tried the Topping for a short time, but the first impressions are that the A90 compared to the Shiit Jotunheim sounds much cleaner and more transparent, I would say even more three-dimensional with a wider soundstage. I wait to see how it will go after a few hours of running in to judge better.
But already now I can say that there is already an important improvement in the quality of listening compared to Shiit.
Trying the HD660S it looks like another headset than before with a detail and a soundstage of greater impact than before. The same feeling also trying other headphones like the HD800S, the Grado GS1000, and also the DT 1990 Pro.
Then trying the top-level handmade headphones like the Italian "Spirit Torino Twin Pulse Isobaric System" the sound is crystal clear, very detailed, almost like attending a live performance.Of course the Spirit Torino headphones sounded this way even before but with the A90 it has improved even more.
