Fosi Audio Box 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

I have a main valve amplifier and needed a phono pre amp to boost signal from an inherited turntable with MM cartridge. Read reviews and got the fosi audio box x2. Being so relatively cheap I thought it would just ok. How wrong i was it's fantastic. Just on the first gain setting is enough for my main amp and tha output is beautiful. I am not a audiophile but I think 10 out of 10 for what I required.

Having recently setup a Pro-Ject T1 SB turntable to go alongside some of my Sonos speakers, which includes an in-built pre-amp, I noticed a lack of depth to the sound output and in particular, a lack of volume available through the speakers. Having done some research on external 3rd party MM preamps, including Pro-Ject's own products, I found some good reviews of the Fosi Audio X2 Phono Preamp, so ordered it yesterday and it arrived by 10:00 this morning (Amazon at their finest! lol). Anyway, it was completely straight forward to setup using my existing phono cables between the turntable and the preamp, plus a new set from the preamp to the speaker, which I bought separately to ensure I had good quality cables with gold-plated contacts. The sound improvement is fantastic, with each of the three gain settings making a noticeable difference to the depth and quality of the output from the vinyl. I may look into different valves in future, to see how they further affect and/or improve the sound of the music, as suggested in some of the other product reviews on here, however my immediate feedback on this products is that it has been a great buy.

I was suffering from interference between my deck and amplifier with current pre amp. All was fixed with this and the sound is so much clearer and absolutely no interference. Pictures show my kit Highly recommend

I got this preamp for my vintage Technics SL-D202 turntable with Technics U25 MM cartridge. Very happy with the results - no hum and nice full-sounding lower and mid range. Recommended.

The Audio Box X2 , was easy to install , GIves a pleasing glow from the twin valves .This phono pre amplifier has transformed my setup , Clear detailed performance. 100% recommended for MM cartridges.

I wasn’t expecting much of an improvement given the price, well I was so wrong. I’m running it with a pro-ject record player into my Cambridge Audio Evo One and it gives the vinyl a very warm and detailed sound. Very pleased with it so far. Seems to be very well made

Well....tubes with blue leds?...maybe they are illuminated this way so that you can see the preamp is on ,rather than trying to see the internal filament of the valves. The preamp itself is very impressive both in build and sound.The gain options allow you to compensate for albums that have low recorded sound and it is seamless when moving the control whilst playing music,should you choose to do so. I upgraded the stock tubes with some Mullards and there was a significant improvement,producing an airy feel...if that's possible?😃 The stock set up is very good but I would recommend a couple of Mullards as the icing on a sweet cake .

Bought this because it was cheap and I had heard a few reviews saying how good it was so I thought I would buy one and see how it compares up against a ifi phono stage. Well it actually shocked me just how good this little phono stage is. The lovely warm sound of valves but surprising real detail and a wide soundstage. That was from the outset and of course as it’s run in the sound changes and it’s got even better. Fosi audio…. Never heard of them it’s not real hifi was what I was thinking…… well it’s blown the socks off the ifi and project phono box that’s for sure. If you’re looking for a phono stage without spending a fortune or just looking to upgrade from the built in phono stage in your amp just buy one of these. Anyone who is upgrading from the built in phono stage in there amp is going to be in for a real treat. The soundstage alone is impressive but that extra detail topped off with that lovely warm tone of the valves this little phono stage is made to impress 10/10

Fantastic product for the price. I have it paired with a Fosi amp and the sound is phenomenal for a budget system

This review is based on 3 whole days of use. For this reason, there will be no mentions of it's longevity, only its awesomeness. I have an Audio Technica AT-LP120XUSB table that's connected the a pair of Klipsch R-51PM bookshelf speakers with a 8" reference series subwoofer. I have been running this system for about a year and a half and have really enjoyed it. The only issue is that streaming content and CDs were so much louder that it bummed me out to listen to my vinyl and only get 75-80% of the volume of the other two. I grabbed this up on a whim. I have the bronze table with the copper speakers and it all looks very nice together, so I figured if nothing else, this little dude would look nice on the shelf next to it, and at like $60, I figured it was worth the gamble. Well, it was. This thing not only offers three levels of volume boost, but cleans up the signal so well that I spent the entire weekend listening to all of my albums over again for the first time. The difference is incredible. I'm not a super-duper audiophile nerd or anything, I just always have music playing and I wanted all of my audio sources to be as close to the same quality as possible. This little box made that happen. If you have a turntable - even one with a built-in phono stage like mine - get this thing! Just trust me. Both my turntable AND my powered speakers have phono amplification, and this is better than either of them. Took a few flips of the switch to get it right (phono from TT to Fosi Box, line in to the R-51s) but now the sound is incredible. Can't believe I went a year and a half without one. Do yourself a favor and grab it now. You will not be disappointed. Side note: the packaging is very impressive. They did a fantastic job protecting this thing and making it look like a thing that should cost more than it does. The directions, on the other hand, are a pretty funny read. For actual setup, bail on the instructions and just google search it. It's not hard anyway.
