Fosi Audio Box X2 Phono Preamp for Turntable MM Record Player Preamplifier with Gain Gear Stereo Tube Pre Amp Hi-Fi Mini Vacuum Pre-amplifier for Record Player with DC 12V Power Supply

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

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 had a Pro-Ject Phono Box Bluetooth but I wanted to switch to wired only (and there is no way to turn off the Bluetooth signal on that model), so I did a search and this little Fosi box got good reviews and I took a punt. Couldn't really tell much difference sound wise to the Pro-ject but that's no bad thing as it sounded good anyway. The little glow from the tubes is quite nice to look at and overall the build is reasonable for the price point. On the highest gain setting there was a little hiss noticeable when my amp was at higher volumes but this went away at middle gain setting, so overall it's good value for money and as long as it stays in working order I doubt I'll want for anything else.

Looking for a second phono pre amp but didnt want to pay £200 plus for another project s2 I did what any reasonable person would do and undertook some research.Typically I googled"any suggestions for a reasonably priced phono amp".It is here I encountered the audiophile snob.These entities sneer at anything that sniffs of budget and try to outdo each other by coming up with the most obscure contraption found on gods earth.A typical suggestion might be say the"Van Den Widerbeest XR46TT"which when you naively try and google find it is either out of stock or there is just one left at only £1250. Which finally brings me to the Fosi Audio Box X2 at £68.Is it as good as my Project S2?No,but the difference is not that great and may be even less if I change the tubes from the default ones supplied.It is easy to setup,just gently line up the tube pins with the holes inside the machine and gently push in.It is atiny bit fiddly but patience will always prevail.Attach the Rca connectors in the appropriate places,turn on,adjust the gain settings and voila.Basically it increases the volume and gives your vinyl a kick in the arse (audiophile technical term,sorry).Its probably not as good as the aforementioned "Wilderbeest" but it does a great job.

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

Replaced existing cheaper pre amp, what a difference it made, brought my vinyls back to life ,well worth the cost and excellent delivery

Fantastic quality little pre-amp. Sounds way better than what it cost

Déjà le poids de l'appareil donne une impression de qualité, mais se confirme à l'utilisation, amplification réglable,son très bon, pas de souffle ou bourdonnement, parfait pour moi.

This Preamplifier is amazingly good for the price and compares favourably when compared to my €1,500 Preamplifier. Appears too good to be true for the price, but it delivers clean smooth musical sound with zero gain noise.
