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

Bought the Fosi Audio Box X1 as it seemed to be highly regarded as a good budget preamp option and so far it works perfectly! It's quite compact and very simple to use (only has an on/off button and then inputs/outputs at the back) and paired with my Edifier R1280T active speakers (would highly recommend those too if you don't want to break the bank) it sounds incredible!

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 transmittersCons• 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.

Works great and sounds good , very good for price

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 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.

No sound out of right speaker

Great little preamp, typical great Fosi quality.

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

Działa ok !!!
