A good thing, and externally, and in content. Increases the signal smoothly, without distortion, the low is not lost, even become more voluminous.
Pulls the sound from the MC head, although it does not seem to be stated. In comparison with budget and built-in amplifiers-victory, definitely victory for it!

I’m very happy to received this phono pream. It is really RIAA compliant. 5 stars for all. Recommended. It is more accurate than the built pream of my Yamaha 501. Thank you seller.

First of all to highlight the seller. Fosi is a company that has earned my absolute trust, they are serious, they ship fast and all well packed and very professional, they are great!
As for the product, it’s the best I ‘ve ever acquired, give your s vinilos a warm, enveloping sound that catches you and fills your room. In my case I bought Fosi the GE5654 tubes that are better than those coming from factory and all very well too. Thanks for the service!

Assembled soundly. Assembled, turned on, works. Low coef. Amplification. There are no declared 45.
And so the sound is interesting low. But do not wait for miracles. Thanks to the seller quickly and qualitatively.

Cool foncorrector, noticeably better than built-in, after reading in previous reviews about Russian lamps also put 6 zh2p sound became even better. I’m happy with the purchase. To the seller and manufacturer of this device for long years of life
A***v –
Very surprised by this device! Better integrated into the water turntable TEAC tn-3b and nad pp375 (module optional in the amplifier nad 356, 375). Lamps immediately put 6 zh2p, with complete ones did not even compare. With above listed Sky-Earth, high crispy, volume, bottoms… I’ll go ahead. I took it for curiosity! But if I immediately heard from those devices this sound, H. Z. Maybe he would have stopped… The nad module has already sold.

Venditore onesto, spedizione da italia, arrivato in una settimana, costa esattamente 20€ in meno che su amazon! Il prodotto è davvero buono, ho sostituito le valvole con le GE 5654w, comprate su amazon. Com dalla riverstone audio (le uniche originali, pagate 23€ compreso spedizione dall america). Quelle che si trovano su AliExpress sono finte. Comprate senza paura

Finaly I got them. Wery long was shipping to Lithuania, about 2 month.
Packed very well, sound good. I like it!
R***n –
The device is decent, but do not wait for miracles: the built-in phono stage pioneer 604-r sounds “lighter”. Here, expected, more “WATS” in the sound, which fully corresponds to the lamp ideology.

Rewelacyjny przedwzmacniacz w swojej klasie cenowej. Współpracuje z AT-LP 120X i amplitunerem Yamaha. Lampy wymieniłem na rosyjskie zamienniki. Piękny, ciepły dźwięk średnicy, z wyraźnym basem i szczegółowymi sopranami. Dodatkową zaletą jest mocniejszy sygnał na wyjściu do wzmacniacza w porównaniu do AT-LP. Jest też coś dla oka… wygląd urządzenia. 😉 Jakość wykonania i wykończenia bardzo dobra. Polecam urządzenie jak i sprzedawcę.
Dziękuję za miłą współpracę oraz błyskawiczną wysyłkę

superb build quality, sound is gratis, will recommend!!

Excellent little phono stage.) The lamps still left their family. Connected to the turntable audio equipment, further into the onkio amplifier. Sounds better than the built-in phono stage amplifier. Adjustment of the gain level works. Looks great in this money. Lamps in the future can be changed to Soviet, experiment with sound. I am happy!
Delivery from Russia is very fast. Packing quality. Thank you seller!

The sound exactly became more voluminous, before that the built-in phono stage was used.
AliExpress Shopper –
Received in less than two days!!
I kept on the box for several hours to work the valves, and after two days I connected in a chain with head AT-VM740ML, turn TT AT-LP120, this pre FOSI Box, AMP Denon PMA800NE and Polk Audio cases Q Acoustics 3020 and satellites S10E.
The result is definitely better than using the while honest pre integrated Denon, the sound will soften, it expands, the cases work definitely better, push even longer, the picture music improves in definition on individual tools, improves the stage, earns all in Naturalness…in short, Not riuscirete maybe to hear the black infrastrumentale or situations esoteric various by audiophiles crazy :), but for the price you paid, in the configuration of the house is a purchase by the relationship q/P super; moreover the box warmer No.
Now think of changing power supply and valves, with other senior quality, as made by other qua…com unque highly recommended!

Not a bad balalaika, delivery in Russia four days. Father nostalgic, looking for domestic lamps. I took it without a power supply, I used the old one from the router.

Неплохой фонокорректор, доехал быстро. Была небольшая проблема с лампами, пришлось подгибать ножки, чтобы правильно попасть в гнездо. Звучит нормально, но не лучше встроенного в ресивер Yamaha R-S700. Брал за 50 баксов со скидкой. Мне он нужен для подключения к самодельному усилителю без фонокорректора. Плюсом является возможность регулировки усиления. За такую цену просто отличный выбор. Рекомендую.

A good phono stage, compared to the built-in amplifier, so generally the sky and earth.
With the seller did not communicate, the order reached 1,5 weeks before the MSC.

Wow, this preamplifier sounds fantastic. I am very positively surprised, of course I recommend it!

Works fine. Sound good. But has a strong emphasis on LF. The top is unexpressive. I’ll accumulate on a normal phono stage, this one will sell.

With lamps 6 zh2p sound is better. Audiophiles are not worth buying, cherishing themselves with the hopes of a miracle-only if you try to play a new toy, those more price for such a sound quality is is is Sound of medium hi-fi, I.E. For the rest of most music lovers, the sound quality will be excellent.

Заказывал из России, пришла за 8 дней до Томска. Лампы реально работают, пока не прогреются звука нет. Звук приятный, более насыщенный. Хотя и на Бриге это слабо заметно. Какие нибудь TDA сильнее преобразит, думаю. Накал есть. Хорошая сборка, приятная ручка усиления,хорошие RCA. Парни, обязательно связывайте Землёй с оконечником хорошим проводом, импульсник даёт на корпус потенциал 55В.

Until Chelyabinsk went two weeks. Looks great! Check yet no possibility, you need to make cables for 5 din. I’ll check it out, I’ll finish it.

All right and without rolling, as the valve needs an average of 150 hours, sounds great. Very detailed the generated sound, for me it has good quality. The background noise from which you always run very low, almost imperceptible, which I like. Generally a good purchase. Perhaps tomorrow morning a more quality valve change could do you better, but for the time being the ones you bring sound great. Seller recommended.

Great thing! I definitely recommend this before and the seller! Sent quickly, promptly answer questions.

Phono corrector received exactly on time. Packing is normal, the box arrived almost no damage. Inside the package everything is whole and lies in its places. The sound of the phono stage reproduces normal, not ideal, but very good. Maximum score for price/quality ratio. At 100% “lamp” this sound can not be called (in the scheme there are semiconductor), but the sound is decent. I recommend this device. That’s what I was counting on.

Well packaged and got here pretty quick. Very pleased with the sound and performance. Very nice little phono preamp. No hum or buzz. Not sure what gain I should set it on for my amp since all of them seem to work with no distortion.
