Fosi Audio P1 Pro Bluetooth 5.0 Tube Pre-Amplifier Mini Hi-Fi Stereo Buffer Preamplifier 6J5 Vacuum Tube Preamp with Treble/Bass/Volume Control for Home Theater Audio System (with Power Adapter)

Amazon music now sounds like vinyl minus the surface noise. I hate digital sound but this little device cures that. Stuck into my old NAD amp and Mission 782s music now sounds great. Money well spent. V. happy bunny.

Worked well, arrived quickly

For the price a great, good working tiny little BT amplifier. I use it to play music wirelessly from my iPhone to a set of Bose 901 speakers via a Yamaha power amp, and a powered 12" Polk Audio subwoofer and I rock the house

Paired this with the Klipcsh R-41M bookshelf speakers and a SMSL SA50 50Wx2 amplifier. While the amp is half of the power the speakers can handle they sound fantastic.Would have given this pre amp a 5 star rating, but the selector switch for Bluetooth or RCA jacks is located in the back. Perhaps the design intent was to be an either or choice, but I switch back and forth b/w my phone (Bluetooth) and my CPU (RCA). I’ll likely open it up and relocate the switch, provide the PWB layout is conducive.

The media could not be loaded.  Prodotto esteticamente molto carino, premetto che sono appassionato di musica da tanto tempo ho diversi impianti hi-fi ma non ho mai provato musica valvolare. Questo piccolo pre amplificatore valvolare è, a mia opinione personale, fantastico bassi profondi e corposi con alti nitidi e ampiamente a largo spettro. In più anche wireless. Grazie

Cercavo qualcosa per pilotare un amplificatore da auto, volevo il controllo dei toni e volevo il bluetooth,ho trovato questo preamplificatore. Non ho molte esigenze e questo prodotto si è rivelato all'altezza. Fa quello che deve fare,poi per il prezzo......per me finora il top.

I have no idea what this unit sounds like because they keep sending an incorrect AC/DC adapter with it. The male end of the adapter does not fit in the female end of the preamplifier. Sent the first one back and the second one has the same issue. Of course, support is non-existent. I don’t understand why the wrong adapter keeps being sent. Does nobody there check it? It’s not because they’re spending all their time handling customer issues.
