Fosi Audio GR70 Tube Headphone Amp

A bit background noise

disappointed at the GR70, usually with a bit background noise even I put all electronic devices away.

Ausgezeichnet!

Sehr gut verarbeitet, der Klang gut aber leicht verzerrt. Preisleistung sehr Gut! Nun ja war angegeben Harmonische Verzerrungen 0.5%, aber ich wollte es doch mal ausprobieren. Fazit empfehlenswert!

Beautiful Amp

I purchased the GR70 to have a tube amp that looked great on my side table. The low cost and beautiful dual channel tubes fit the bill so I bought it. When paired with my Focal Celestee headphones which are quite sensitive, there is a little bit of noise from the tubes on high gain, though that's part of the tube charm! Important note - This is only noticeable when there's no audio playing though so doesn't detract from most music listening, though does come through on tracks which utilise silence throughout. When paired with less sensitive headphones like my Sennheiser HD6XX or Hifiman HE-X4, I can output as much power as I like and can't hear any noise from the tubes. Overall, if you're after a tube amp that doesn't break the bank, the GR70 is an easy recommendation and I'd definitely purchase again.
