Fosi Audio BOX X1 Phono Preamp for MM Turntables with 3.5MM Headphone and RCA Output, Mini Phono Preamplifier with Power Switch for Phonograph/Record Player, DC 12V Power Adapter Included

Works great and sounds good , very good for price

For the price, a perfect little preamp that functions really well and is small enough to not be in the way. Works well with my turntable and Edifyer speakers.

The Fosi Audio BOX X1 with an MM turntable, feeding a Bluetooth transmitter which then connects to my Roth VA4 active speakers. Setup was very easy and worked first time. The turntable goes into the BOX X1, then out to a UGREEN Bluetooth transmitter (set to transmit mode), which pairs wirelessly with the speakers. No apps, no screens, no messing around, just buttons and LEDs. Once paired, it reconnects automatically. Sound quality is better than I expected for the price. The BOX X1 is quiet, with no noticeable hum or noise in my system, and it does a perfectly good job of phono amplification. Over Bluetooth, the sound remains clear and balanced. Yes, Bluetooth is technically lossy, but in real listening terms the loss is mostly academic. I wouldn’t notice it unless I was directly A/B testing against a wired connection. There is a small amount of Bluetooth delay, but in a vinyl-only setup this doesn’t matter at all. It has no impact on listening enjoyment. Overall, this is a very good value phono preamp. Paired with a modern Bluetooth transmitter, it’s a practical and affordable way to get vinyl playing wirelessly without sacrificing sound quality in any meaningful way. Pros • Easy to set up • Clean, quiet sound • Great value for money • Works well with Bluetooth transmitters Cons • MM cartridges only • Bluetooth is technically lossy (but not an issue in practice) I’d happily recommend this to anyone looking for a simple, budget-friendly phono preamp.

I bought this (X1) to connect my old Dual 505 turntable to a Denon amp/cd player, so regaining access to playing albums after many years! A joyful moment ! It's easy to connect with the Amazon Basics RCA cables and works perfectly - providing excellent sound quality. I'm very pleased with this product, excellent value for money.

Perfect Compatibility with my Yamaha AVR-S80 sound system, crisp sound quality, small and perfect size for where I needed it, runs off of a uk plug, cable length I thought was going to be a bit short but luckily it was just the right length, supplies enough power from the socket to the preamp

I used the unit as a phone pre amp between a TEAC Turntable and Denon Amp. The Denon amp does not have a phono input function. The pre amp functioned as specified into the Aux input. The sound appeared to be acceptable at least to my aged ears. I can now play my LPs and 45s. The pre amp looks well made and small enough to be tucked away out of sight, although you do require access to the power button.

Great little preamp, typical great Fosi quality.

I have this between the turnable and my speakers. If I just have a direct connection from turntable to speakers it works fine. Add the preamp I'm the middle and the sound becomes very distorted. Am I using this correctly?

I’m very pleased with this amp. Packaged nicely. Looks great. Affordable. Sound/volume is good. works well with my turntable. Exactly what I needed. I would recommend.

Netjes een in Duitsland ontwikkelde phono voorversterker in China gemaakt. Dus goed ontwikkeld en (jammer genoeg) goed gebouwd in China.

Działa ok !!!

Fosi good products

Preamp phono de boa qualidade. Ótimo custo-benefício. Utilizo-o com o toca-discos Áudio-Technica 120X e caixas da Edifier. Estou satisfeito com o som que esse conjunto de equipamentos produz.
