Uzun zamandır fosi audio ürünlerini satın alıyorum. Zamanından önce teslim ettiği için Amazon'a ve de kaliteli ürünleri uygun fiyatlarla sattığı için fosi audio ' ya teşekkürler. Bu cihazı; Fosi' nin BT20A pro amfimin çokta parlak olmayan sesine katkı sağlar ümidiyle aldım. Genelde yorumlarda V3 ile eşleştirenlerin yorumlarıni görünce satın alırken biraz tereddüt ettim. Çünkü bu amfilerin zaten bir preamfi özellikleri vardı. İkinci bir ön amfi ile nasıl eşleşir endişesi taşıdım. Ama sorun olmadı. Bağlantılarını yaptım ve çalışmasında herhangi bir sorunla karşılaşmadım. Bu cihaz, BT20A pronun sesini daha açık hâle getirdiği gibi bas ve tizlerde de belirgin bir iyileşme sağladı. Bazı yorumların aksine tüpleri yuvalarına yerleştirmek iki dakikami aldı ve takarken hiç zorlanmadım. Bu arada bir tespitte bulunmakta yarar görüyorum. Bu cihazlar küçük ve her bağlantıyı bu kutucuğa yerleştirmek zor olabilir. Ancak yine de preamfi katıni daha kaliteli yaparak ve fiyatını o oranda yüksek tutarak insanların sürekli başka cihazları satın almak zorunda bırakılmaması yararlı olur diye düşünüyorum. Ancak bu tespit ve öneri; Fosi' nin işine gelmeyebilir. İlave özellikleri olan cihazları üretmek ve çeşitlendirmek günümüzün bir satış politikası olabilir. Ama yine de fiyatı biraz yüksek tutarak daha entegre edilmiş ve ses kalitesi artırılmış cihazlar üretmekte iyi bir pazar yaratabilir.

I bought this Amp to drive my Focal headphones and it does a really nice job. The sound is clean with a good sound stage and just need a small amount of bass to drive the headphones. I was not expecting to much but this Amp has exceeded my expectations. Out of curiosity I connected the P3 Amp to my NAD C270 Power Amp which is driving a pair of $15,000 Focal Mini Utopia speakers and I am very surprised at the quality of the sound. Again it has clean sound the low end frequencies have clean bass to them, the mid's are clear and articulate and it has good high end extension. It has a wide sound stage with good instrument separation. I would recommend this little power house of an amp to anyone. Well done Fossi on a good product at a very low price.

I have been following fosi products. There are mixed reviews on Reddit and youtube some just branding it as cheap chifi setups. I wanted a Bluetooth transmitter and I was eyeing on fiio but that was costly so this was another option. I didn’t need an amplifier though. So this preamp was a good option. I personally like old vintage songs and warmth. So tube amps were a good option for me. The only question was whehter the build quality and sound quality would be good? Once I received, I connected it to my studio monitors and I could understand the warmth from the tubes. Then I listened to it by connecting on my IEMs, warmth is noticeable. The music becomes more enjoyable to hear. Soundstage is not that wide. But the bass and treble controls are really nice. Bass noticeably gets boosted at 12 o clock position. The volume button increases non linearly. It has enough amplification for IEM that I never get past the 12 o clock position, so I guess it would be able to drive full sized headphones also. One con would be when there is no electricity and when I play it on the inverter there is a hissing sound (some kind of weird earthing issues Iguess, because same thing happens for my studio monitors also) Conclusion - it has impressed me with the sound quality and build quality. Maybe better tube amps will be out there but this one is a good starting point.

この商品は、インテリアとても良いと思います。 まず真空管部分ですが、通常はオレンジ色の電球色のみですが、青混じりで光ます。 音に関しても充分な出力があり絞って使用しています。 間に改造修理したイコライザーをかませていますが相性バッチリでした。 DACからイコライザーに繋ぎイコライザーから二つのアンプに分岐して電源Switch切り替えでヘッドホンとスピーカーの切り替えをしています。スピーカーの音とヘッドホンの音が近い音質で聞こえるので違和感なくかなり良いです!! pcの純正ジャックに繋ぐと同じイコライザー繋いでいない為音が違うのは当たり前ですが、やっぱり耳に突き刺さりました。 それぞれ個人独特の環境作るのに役立つと思います。
