Impresionado

He comprado este equipo hace algunos meses, tuve un inconveniente al principio pero el equipo de fosi impecable atención post venta, destacable.
En cuanto al equipo cambie de válvulas por unas NOS GE 5654w y suena muy bien, mejora notablemente respecto de las stock .
Ecuación costo/beneficio es imbatible

Dark sounding unit

Fosi support team just dont know the meaning of Money-Back Guarantee!
contacted them on Whatsapp and still they throw me in the loop of no return the product and refund.
I have the treble on max all the time and still hearing the sound is DARK (Very warm), checked the speakers and cables all good no problem but fosi still not doing anything.

low volume cutout not for classical music

A very nice unit, but for classical music the built in low volume cutout at 500 microvolts in not acceptable. Is there a work around for that? even in other genres the transition to zero volume is jarring.

Bad experience

Excellent finition but mine was hissing after a few minutes. I repeatedly asked Fosi for a refund but never obliged.
Once but not twice in my case.

Absolutely stellar.

What a beauty, all the functions it has round the back are unbelievable. Yuz have done a brilliant job of design and manufacturing.
