    Works great in home audio

    Good sound, Bluetooth connection good. I use it for a sound system in a basement workshop, streaming music from my cell phone or laptop - not an audiophile situation, but efficient and economical.

    Pros
    • Slim design
    Cons
    • Slightly wrinkled

    Outstanding sound quality

    I've been looking for the right turntable preamplifier for 2 different surround receivers for many years. I've tried at least 3 or 4 in the past but wasn't entirely happy with their sound reproduction. Finally, this new preamp does it as well as it gets. Ideal!

    Pros
    • Cool
    Cons
    • Minor problems

    Looks great and sounds great!

    I used to connect my turntable directly to the receiver and although it sounded good I had to crank the receiver to full power and the sound didn't sound that good. Had a lot of success with another Fosi Audio gear (amplifier) so decided to try this preamp. It's great, sounds good and looks really good next to a turntable. Now my vinyls sound a lot better. I love this little preamp.

    Pros
    • Few competitors
    Cons
    • Modern

    Terrible hum when turning on

    At a quarter (nine o'clock) the volume was surprisingly loud and very, very bright; too bright. When the volume was turned up past a quarter, there was a very loud hum, almost like feedback. I've tried moving the preamp closer to the platter and then further away, but got the same result. I checked the ground and cable again and everything was connected correctly. I disabled it because I didn't want to damage my Klipsch Cornwall speakers.

    Pros
    • Done
    Cons
    • Nothing here

    Great phono preamp for the price

    I needed a phono preamp so I could use my turntable without having to turn on the AVR every time I wanted to listen to a record. This preamp is exactly what I'm looking for and I know it will work great as everything I've bought from FOSI Audio has been top notch. The device is delivered well packaged so that it will not be damaged during delivery. All you need is a cable to connect the player and cables to connect to the amplifier. I connect it to a FOSI Tube-P1 which I then connect to a…

    Pros
    • Great for a small home
    Cons
    • Poor kit
