Fosi Audio P1 Mini-HiFi-stereo-voorversterker, 6 K4, vacuüm voorversterker, met basgeluidsregeling, voor hifi-thuisbioscoopsysteem (niet voor platenspeler)

Really impressed with this unit, it delivers as you would hope. Which is pretty amazing for this amount of money. I tried on several sources (drummachines etc) and its works like a charm. Also the case feels very sturdy.Only con for me is the led lighting, i would rather see an indicator near the switch. But I cant complain really for €49 !

Deze aankoop was mijn tweede P1. Ben over het algemeen positief over deze pre-amp. Het wisselen tussen verschillende buizen geeft nauwelijks verschil. Alleen de 5654 geeft enige verbetering, maar eerlijk is eerlijk, nauwelijks hoorbaar. Ik zou deze P1 vijf sterren hebben gegeven ware het niet dat mijn eerste binnen 6 maanden kapot is gegaan. Linker en rechter kanalen vielen herhaaldelijk uit en de volume knop haperde op het laatst continue. De bouwkwaliteit is beneden peil. Ondanks de lage aanschafprijs zou die toch langer mee moeten gaan.De tweede doet het naar behoren en gaat hopelijk langer mee.Overigens gebruik ik deze pre-amp voor volume regeling voor mijn twee Fosi V3 die zijn ge- bi ampt. In zijn geheel klinkt dit fantastisch.Resumerend: bouwkwaliteit onvoldoende, geluids ervaring meer dan goed.

I have all my music on Windows media player. I run that through an external digital to analogue convertor or Dac as it's known for those less in the know. This bypasses the inferior music chip in the computer to give superior analog sound and then straight into the rca on my 5.1av reciever. I was enjoying the sound but there was something lacking and I was constantly tweaking the sounds on the amp and equipment on the media player. So frustrating. Then I was hearing talk on cheap audio man channel on yt about preamps and how they can improve sound quality when added to the end of the chain into the amp it's self. He was reviewing this tube amp model. Check him out! I have no associations with him..I'm just a fan of the very informative channel as I'm no audiophile..but I know great sound when I hear it. At this price I was sold and I had nothing to lose. Anyway I've set it up and I'm blown away by the difference..it's night and day! Better presence, deeper richer lows mids and highs and crisp vocals. This is my first dive into preamps...even yt 320kb files are stunning! The unit is solid metal construction and doesn't feel cheap. In fact it's the opposite. I upgraded for the upgrade recommended tubes. The standard still come supplied. Vonnecyions are simple. I'm enjoying my music all over again. Beautiful product wow. Thank you Fosi for such an excellent product and cheap audio man for the review. Don't be misled by 'cheap' audio man. That's an understatement. His philosophy in.my opinion is that you don't have to spend huge bucks for great sound.

Pour le prix, c'est bluffant.j'ai un ampli transistors d'une grosse marque japonaise, vintage 80W, je ne voulais pas le changer car il fonctionne très bien, acheté pour une centaine d'euros. Et le changer pour quoi... j'ai cherché dans tous les sens, je ne peux pas avoir de garantie qu'une autre marque soit meilleure avec mes grosses enceintes colonnes 3 voies avec mon petit budget ridicule. Je n'ai pas le temps de tous les acheter pour les tester.Le son de mon ampli actuel restant superbe, très puissant, très détaillé, il s'avère quand même trop sec sur les morceaux de guitares saturées, rendant l'écoute fatigante sur le long terme.Ayant à l'esprit que dans un ampli intégré, souvent c'est le préampli qui pèche tandis que, dans un ampli intégré, c'est lui le plus important pour la qualité du son...Etant donné que la faveur des audiophiles allant plutôt sur les amplis à tubes, je me suis dit que choisir un préampli à tubes pour rentrer dans mon ampli transistors serait une bonne idée... Je n'ai effectivement pas les moyens d'acheter un ampli à tubes à 4000 euros, 50euros, ça me va bien.Eh bien bingo, ce petit préampli répond à mon cahier des charges. Le meilleur des deux mondes ! Le son est sacrément amélioré, c'est un plaisir.Il ne faut pas monter trop le son du fosi, à un tiers c'est bien, sinon il sature au delà.Testé avec d'autres tubes aussi, nickel.GENIAL BRAVO FOSIje recommande à tous ceux qui ont un ampli transistors un peu sec.

Das Gerät kam neu unversehrt an,habe das beiliegende Netzteil gegen ein besseres getauscht ohne Leuchte man hört kein brummen rauschen nix.Regler rasten schön hin und her wirken massiv.Entgegen der meisten Leute entschied ich mich gegen die JAN Ge 5654w ( hab ich hier liegen ) sondern für ein anderes Fabrikat und derweil werkeln die Stock Tubes die nach Anpassung der Regler deutlich ganzheitlicher klingen.Macht deutlich mehr Spaß als ohne Röhren man sollte aber auch die restliche Anlage mit berücksichtigen.Betrieben wird das an alten Valvo 30cm Breitbändern inklusive sub und da passt das super zu wie das aber an fertigen Boxen wirkt kann ich nicht sagen.Fazit wer auf das Sounding steht kann hier wirklich unfassbar preiswert zugreifenEinzig das man halt nur eine Quelle hat ist etwas doof aber auch bei der größe kein Wunder

I bought the Fosi P1 and use it with 2 of their M02 mono/subwoofer amps, and I was very pleasantly surprised at the overall sound. I let the P1 and M02's warm up a bit for about 10 mins before beginning to listen. The sound was detailed and clear. After listening for about an hour,.the sound began to warm up. After about 3 hrs of continuous listening, the bass got deeper and more punchy. After about 5 hrs, LP after LP, the sound remained steady and consistent with the soundstage getting deeper. The sound was smooth and just flowed as good analog should. I did all my listening to my modded Audio Technica AT1240 turntable, Hana SL cartridge with Moon LPS110 v2 phono preamp and Klipsch RP160M speakers and 12 gauge multi-strand wire. Since the P1 has only 1 set of RCA inputs, my phono, laptop, cable box, and tape deck all go through my 20 yr old Great American Sound 5 way input switch box. The sound quality was warm and very lush. Great for jazz and other acoustic music. But, to compensate, for the added warmth, I adjusted out my speakers about an extra foot from the wall (now about 3' in total). However, the top end lost a bit of airiness and transparency. Fortunately, the bass and treble controls are of high quality but, as with all tone controls, should only be used judiciously. By leaving the bass "flat", and adding about 0.6 db of treble, the transparency returned with more realistic dynamics as well.That is where the tone settings will remain. I'm very satisfied with my new "small and compact" set up. Kudos to Fosi Audio for such high performing units.Update: After listening for about 40 hours, I realized that I can listen to my P1/M02 combo with the tone controls "flat". So as the stock tubes burned in, the quality of sound continued to improve. Anyways, as a result of the fine reviews of the 5654W, upgraded tubes from Fosi, I decided to order them. I have been listening to them for about 30 hrs now, and as good as the stock tubes are, these 5654W's have added an extra dimension of depth and clarity to the sound. Everything from the deep bass to vocals, to various instruments have tightened up, increasing the sense of rhythm and dynamics. Most enjoyable indeed!
