Fosi AudioBox X2 Phono Preamp, Mini Stereo Audio Hi-Fi Preamplifier with Gain Gear, Pre-Amplifier for MM Turntable Phonograph and Record Player, with DC 12V Power Supply

Amazing little amp. It looks beautiful. Provides incredibly strong signal to my speaker. I connected this little tube amp to my Audio Technica SL-1200MK5 turntable. The original output from the turntable was too low, but after adding this amp, it’s crazy loud now. Even at the lowest setting, I have to adjust my speaker to be at like 5-10% for comfortable volumes. So it definitely works! It LOOKS amazing, when warmed up, the blue lights and the soft warm orange glow of the amp looks so good. It’s small and fits right on my shelf. It comes with a GROUND screw, thank goodness for good design. My turntable has a ground pin and I didn't have a reliable place to connect it too, but glad this little unit had a place for it. The really helps eliminate any additional noise and the tube amps really help warm up the sound. Tube amps provide odd order harmonics which help make your vinyls sound richer and warmer; coming off from a digital amp, I can definitely tell the difference. Had to be a little careful when installing the tube amps, but glad we can replace them over time as needed.

I will come back if burn in changes everything, but so far this box is everything I wanted it to be. My Audio Technica LP60 TT isn't known to be a Cadillac, but I love it's form factor, and easy use. However, the built in preamp leaves much to be desired. I've had a few really nice turntables in the past, but didn't realize quite how muffled the stock LP60 sounds on my Sony reciever. After a few recommendations, I picked this lil guy up hoping it would resolve having to max my receiver, and possibly have clearer quality. I plugged it up as soon as it arrived today. I was BLOW AWAY at the audible difference. If you play your records alot but don't have a seperate preamp... Buy this. I'm serious. An immediate game changer. Set to 42 and let it work it's magic. Very well rounded clear sound with a much needed bump in the signal amplification. It sounds great on everything I've thrown at it today... From King Gizzard, Justice, Umphrey's, Zeppelin, and even Prince. It's brought detail Im not sure I've ever heard in my vinyl in the past. I can't lie, I'm upset because I should have had something like this 25 years ago. Don't hesitate, well worth the price plus some!

I wanted to move my Audio-Technica AT-LP60X-BK turntable from my living room and its connection to a Denon AVR with a phono preamp to a separate room. Although the turntable had options to use either its built-in preamp or adding a phono preamp, and my amp in the new room didn't have a phono input, I decided to try out several inexpensive phono preamps (from $50 to $120). Initially, I purchased two of the more modest ones, this Fosi X2 and a Nobsound/Douk T3) to go with a system consisting of a Douk H7 Pro amp, Aiyima DAC-A2, and Elac speakers). I "a/b'd" the turntable's internal preamp vs. the Fosi, vs. the Nobsound. Immediately noticeable was that both preamps blew away the crappy internal preamp on the turntable.Nest, I put the Fosi and Nobsound head to head against each other. It was READILY apparent that the Fosi was significantly more alive than the Nobsound. In fact -- and I've been in music actively and passively for more than half a century -- it's hard for me to believe a record on a turntable (I used Journey's seminal debut album) could sound any better. I swear! There definitely seems to be more stereo separation where the lead guitar and vocals popped out of the mix, and the overall presence of the music was more robust and detailed (than the Nobsound). The completely negated my auditioning the other two $100+ preamps or any others I might try because the music was already beyond enjoyable already at under $70! I might also mention that the reviews of the Fosi X2, compared to another handful of turntable preamps in the same Fosi line were extremely strong (I look for a clear winner in the percentage of 5-star reviews). I can confidently say that the Fosi Audio Box X2 is simply the best phono preamplifier value for the money, and to my ears, doesn't scrimp at all on sound quality resulting in a profoundly WISE buy!!

Mostly happy with the device, it is well designed and put-together.My only issue with it was that I found the included power supply to be inducing some high frequency noise (switching noise?). my AT-LP60 does not have a separate grounding terminal, but I verified the RCA sleeves were all bonded to ground through the devices.Removing the Box X2 from the signal chain eliminated the noise, even with the V3 amp turned up all the way. If the X2 was in the chain, I could only turn the V3 up to below halfway (12 o'clock on the knob) before the noise became unpalatable.I replaced the small 1500mA power supply with a known clean 12V supply I had and the noise was eliminated (I even verified the noise was not from the record player's power supply).Maybe it is just bad luck and I got a bad power supply.YMMV
