Review on 🔊 Fosi Audio DA-2120A Bluetooth Amplifier Stereo Hi-Fi 2.1 Channel Wireless Stream aptX, 24Bit/192kHz Class D Compact Mini Power Amp with Integrated USB DAC Coaxial Optical, Subwoofer Support & Remote Control by Lori Lopez

I was a big audiophile for many years (snake sized cables, expensive air conditioners etc) but a few years ago I matured into the lite version (nameless cables are just as good as expensive ones), cheap, but great sounding components etc). I'm preparing to move, so I packed up my main system (worth $3,000) and bought a Fosi as a compact and lightweight emergency amp/DAC to last until the move was complete. Considering the price I wasn't expecting much. I was wrong. This amp is shockingly good! I am using the USB input from an Intel NUC and the detail and transparency from this amp is amazing. I'm listening to Patricia Barber's Cafe Blue and typing that grin from ear to ear. The speakers are Klipsch Quartet V (largely unknown and underrated) mini-monitors paired with a 10-inch Dayton Audio Sub-1000 subwoofer. Without the NUC source, the kit costs about $350). It doesn't look like a $350 system. It sounds more like a $1,000 entry-level audiophile setup. The remote control, while not very convenient, is comfortable to hold and has useful shortcut controls such as bass/treble and volume. A few caveats: 1. Play with the equalizer settings as they greatly affect the sound quality. I personally like the rock mode best for all music genres. One feature I would like to have in this unit is a variable high pass filter for the speakers as it reduces loading on the relatively low powered amplifier section. BTW, for best results try using speakers with a sensitivity of 90dB or higher in a small to medium-sized room (this little gem is perfect for that - my quintets are rated at 91dB). Finally, you should know that this is not a warm and fuzzy sounding amp. Rather, it tends toward reckless disclosure, which isn't necessarily a bad thing from an audiophile's perspective. The amplifier will quickly tell you if your playback source is of high quality or not. Try Foshi. I hope you will be as pleasantly surprised as I am! PS: The audiophile show Rocky Mountain Audio Fest is coming to Colorado in early October. I'm going to be attending and want to set up my $400 rig (including a USB streaming source) in one of the smaller rooms with good basic acoustic treatment ($100 for common household items: heavy curtains for example). I hid the components and asked the participants to estimate the price of the system. I'm guessing no one will make less than $1,000 at an average estimate of about twice that :-) Peace to all!
