Best value for money
Amazing value for the money. You’ll need to spend much more to get better sound.

Been using for 2 weeks now, plugged into a JBL Partybox 120 from Technics 1200 and have no complaints! Great little preamp that makes the vinyl sound pop with full spectrum sound, mids and accents well distinguished. Very simple to use, once you dial in the db level selector it does the rest and you control the volume on your amp. Low key but good price for the value IMO. Far better than a basic solid state preamp i was using for the past month that boosted the signal but was not as dynamic soundwise. And 1000% better than a more expensive tube preamp that was returned within 2 days b/c it compromised the high and low end. That one looked super cool but had to go.

I bought this after a lot of research. It actually delivers what I found out through the research. If you need a phono preamp without a hole in your pocket just buy Fosi X5 and look no further. It instantly gives the required kick for your vinyl setup. Satisfying to the core.

Mejoró notablemente el sonido de mi toca discos Denon DP-400 Se notan mucho más los tonos bajos y en general el sonido es más abierto , energético, claro . incluso se logra más volumen .

La première chose importante est que juste avant de commander ce preamp, je songeais à retourner ma tables tournante Audio technica LP60X, non pas car elle ne jouait pas bien. Elle jouait bien, aucun problème de saut etc mais le gain était extrèmement bas en sortie avec le preamp intégré et qu'il manquait quelque chose au son qui était ordinaire. J'ai testé un petit produit passif à 70$ et j'ai une petite amélioration mais rien de significatif. J'ai donc procédé à deux upgrades. J'ai changé le stylet pour le 3600LE, très grande amélioration du son et ensuite ajouré le Fosi X5 et là, la magie a opéré. Quel rendu, quel gain et la switch est sur la deucième position. Je suis allé cherché beaucoup de basse et d'aigue, de la clarté etc...La boite est pesante, solide. Ca ne ressemble pas à une pièce cheap. Je suis très satisfait de mon achat, je vous le conseil. Je songe upgradé ma table vers quelque chose domme une Fluance RT82...donc j'ai déjà mon petit pream champion :)
