Opened up the sound
This perform better than the inbuilt phono stage of the turntable or the onkyo receiver. The voice is warm and pleasent. A good stylus with the phono preamp is a must if you have a turntable.

Works fine but power adapter not suited for UAE
This item does the job with my record player (Fluance RT85) however one little gripe is that the plus is not suitable for UAE/UK - it is a 2 pin plug. It is on the product page as an image (not text) but after some scrolling - would help if its in title description. Small gripe to an otherwise great product.

I have never written a review on Amazon, or anywhere else that I can remember. But his product seems special. I read the reviews and thought “no way, this can’t be that good”. But I was also looking at a so-called affordable audiophile preamp that cost literally 10 times as much as the Fosi, so it couldn’t hurt to try the little guy. I’m so glad I did. Straight out of the box it put the in-built preamp on my Klipsch The Sixes to shame, it opened up the speakers in a very nice way. And this is before any tube burn in and literally from a cold start. The sound is balanced and inviting. Absolutely perfect for pleasurable listening, I can’t find any harsh edges anywhere. For the price, I was expecting a much muddier sound, but the clarity is surprising. I like clarity, especially on vocals, so this is a plus for me. I’m writing this at the end of a 3-hour listening session, that’s gotta count for something. This little preamp is so good that it made me specifically search for other Fosi gear, I’m about to purchase one of their DACs to test out. You see, products like these bring me hope in the world of Hifi, where every little magic box seems to cost a years’ salary. Good to know one can actually find decent quality at prices that encourage people to experiment, rather than buying something and having to force oneself to like it because the financial commitment is so large. I’ll definitely be keeping an eye out on this brand. We’ll done Fosi!

Sehr guter Pre-Amp. Klingt überdurchschnittlich gut. Angenehmes Klangbild.

not as attractive as some of Fosi's other products but works very well ... - i use mine with my SL1210 turntable and it does the job of a preamp perfectly well
