Ich habe das Gerät am PC angeschlossen über USB und brauche
den mitgelieferten Stromanschluss nicht. Ich bin 68 und kann
hohe Töne nicht mehr richtig hören. Das ist auch schlecht
beim TV gerät. Ich höre ausschließlich über Kopfhörer um
einigermaßen alles mitzubekommen. Ich habe über Jahre viele
Audiozusatzgeräte gekauft und wieder entsorgt weil immer
etwas für mich immer etwas klanglich nicht passte. Aber
das DSD Gerät ist das erste wobei ich mich nicht ansträngen muss
um Sprachen zu verstehen. Ich höre wieder höhen in den Stimmen!
Und den Bass kann man aufdrehen ohne das es Überschlägt. Sowas
habe ich in meinem 68 Jahren noch nie erlebt (Satte Bässe ohne
Rumpeln) Mein Kopfhörer ist ein Philips Fidelio X3. Am TV über
S/PDIF Anschluss war immer alles zu Dumpf. Selbst das ist jetzt
Klar und deutlich zu verstehen. Ich hätte nie gedacht das so ein
kleines Gerät mich so stark beeindrucken kann. Mein 30 Jähriger
Sohn der hauptsächlich Online Spiele spielt, will sich auch ein
Gerät kaufen wegen der Klangreinheit.

Super Klang ,bezaubert ...

Diese Kiste ist der Hammer ! Eine Auflösung und luftigkeit Spitze! Auf pure geht der Vorhang auf ,toll! Gehe über usb c aussen samsug tablet S7 linear in die tolle Kiste! Wird gleich erkannt ! Dann von der tollen Kiste aus der Kopfhörer buchse in ein beyerdynamic 250 Ohm kopfhörer 🎧! Lautstärke ist ausreichend! Auch die optcal in /out sind zu gebrauchen vom Sound ! sind vom poti nicht geregelt ! Der cinch Ausgang ist leider übers poti geregelt ! Die Kiste macht richtig Spaß! Ein Tuck mehr Höhen macht die Kiste! alle Informationen auf der Musik sind über das ganze Spektrum zu hören ! Noch im test war der fiio btr 5 und qudelix 5k ! Alles top Geräte ! Die tolle Kiste macht Freude ! Berieselung pur !

Great desktop amplifier for headphones

Effective, good build quality and fairly robust connectivity options. I use this as a DAC, over USB-C to a PC, and it performs very well, much better than my integrated audio card. I’ve found great results with both my Audio Technica headphones and AKG 271 mk2 headphones, the latter of which really shines when fed with this amplifier.
