Very good upgraded from douk audio t4 pro this one has much more bass that’s why I bought it. Have it connected to a Rockville blutube and fluance rt 82. The sound is pretty good for the price love that you can adjust the sound to your liking. The clarity is good very easy to set up. It gets loud but I have good hearing so you might think otherwise. It’s nice and compact. Bluetooth is good Power is good too. Overall very good inexpensive pre amp.

PROS-Pleasantly surprised that it really does improve the quality of the sound coming off old vinyl records. It actually does restore much of the analog tonal character I remember from my old records dating back to the 1960s. I am using a TECHNICS turntable with a SHURE M95ED cartridge. I am listening over a Koss Porta Pro headset - which I consider a neutral and unbiased output - vocals are richer are more realistic. Orchestras sound more like a live performance. Classic pop sounds new and fresh again. Overall, details in the music that were forgotten or lost are back again. I would describe the processed sound as smoother and richer than running without it.The separate TREBLE and BASS controls are a good idea to help tweak the sound. For most records, I run T@12 oclock B @3. I generally keep the VOLUME @11oclock or less. If you overdrive the output to your amp, it spoils the enhancement.CONS -*Turning power ON or OFF sends a loud thud through the system. There is no dampening at all.*It lacks a headphone output*It lacks any visual indicator of output level*It seems cheaply built and I have concerns that it won't last.Have not tried digital inputs from CD or MP3 player via wire connection or Bluetooth but if and when I do, I will attempt to update this review.

I needed a phono pre-amp, and while my receiver has the capability for bluetooth connection with phone, laptop, etc. the sound quality was really unimpressive. I saw lots of options for pre-amps, and lots of options for bluetooth receivers but not a lot of devices out there that did both… until I noticed this affordable unit. Fosi audio seems to be pretty well regarded in the budget audio community, so when I saw this little box I figured it was worth rolling the dice. I’m glad I did.This pre-amp added warmth and character to my vinyl AND the bluetooth connection was a huge improvement in sound quality over just connecting directly to my receiver.For the price what more could you want? I will say even with the volume dimed you’re not getting a crazy amount of gain. If you have the option on your receiver to boost the input, you might want to try that.With treble and bass controls and dual functionality of phono AND bluetooth capability, and given the fact that this little box takes up almost no space I’d say you’re getting significant bang for the buck. It will let your vinyl really sparkle and bring some warmth and dimension to whatever device you’re streaming via bluetooth which might sound sterile otherwise.I’m not sure what else you can get for this price that will deliver results like this in both sound quality and functionality for your system.

Works great, easy to connect both with Bluetooth and wireless. Clean, warm sound. Great quality for the money. Compact and functional. Analogue volume, bass and treble.Just make sure you install the tubes properly, pushing firmly but gently.

The media could not be loaded. Power:Exceptional quality for the price point! Set up was a breeze-5min.I use this pre amp to feed signal to my Kenwood kr-a5020 receiver from my iphone or turntable.Sound is crystal clear with tight non distorted bass and crisp highs. Buy with confidence.*****

Overall I’m only giving 3 stars due to build quality, the metal housing feels nice but both of my tubes are off center and slightly crooked, there’s more mains hum than i’d like but maybe if I upgrade tubes.
