Fosi Audio Box X5 Phono Preamp for Turntable, Mini Preamplifier Home Audio for MM & MC Cartridge Turntable/Phonograph Record Player/Active Speakers, 4-Level Adjustable Gain 38/48/56/66 dB with RCA

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.

Very good quality and definitely value for money

Good product

Excellent

The phono stage on my Rotel A14mk2 honestly sounds better. This is strictly for who want to upgrade from their turntable's inbuilt pre amp or dont have one at all. Most likely your amp will have better phono stage than this device. Also the higher gain levels of 56 and 66db are useless on this unit; grossly distort 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.

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

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 :)

After reading reviews and watching the videos from the HiFi community and seeing the specs put to the test from places like Audio Science, I pulled the trigger on this phono preamp and I am glad I did. Really brought out the best from my Sumiko moving coil cartridge. It's beating out competition that's three times the cost or more. Do yourself a favor and grab this unit if you're in the market for a phono preamp. Edit: So after about a week the unit stopped working. No output from either channel. Sounded great and was very pleased with this preamp but then it just turned it's toes up and does not function. What a shame. I'll be avoiding a replacement and just get a refund for something better. Edit 2: Update 3/12/25 - In response to my feedback, Fosi reached out to me and offered a replacement that has been updated. As of today, I have been running the replacement for two days with some extensive playtime and the sound is as good as I had remembered and it is holding up. Last time was a week before failure, so in another week or two I will update again. I must say that their customer service and dedication to providing a quality product is refreshing and welcome. Edit: Update 3/21/25 - After a week of running a moving magnet cartridge (38 dB gain setting) and a high output moving coil cartridge (48 dB gain setting), things have been smooth with the new unit. Sound is amazing and there is still zero noise from this preamp. I'm now on day 3 of running a moving coil cartridge with 0.5mV output using 56 dB gain. It is working flawlessly. In a few days I will switch to a 0.3mV output moving coil cartridge and utilize the 66 dB gain option. If all goes well I will give one final update. Seems things have been sorted out and this phono preamp from Fosi is working magic. Edit: Update 3/27/25 - Almost three weeks in now and the replacement unit has been working flawlessly. At this point I would have to say that Fosi made sure that they addressed any issues and were definitely aiming at providing a quality product. Their customer service was exceptional and this phono amp I can honestly say is one of my favorites. It provides above par sound quality and there is no distortion or noise from this unit. I've adjusted my rating...for sound and cost, this really cannot be beat. I would give it a final 4.5-4.75 stars.
