Fosi Audio BL20C Bluetooth 5.0 Stereo Audio Receiver Amplifier 320 Watts 2.1 CH Mini Hi-Fi Class D TDA7498E Integrated Amp U-Disk Player for Home Passive Speakers Powered Subwoofer(with Power Supply)

I am NOT an audiophile. But I love music. I have 4 systems set up in my house in various rooms, all using these excellent little boxes. I get my music from Alexa 3rd and 4th generation Dots. I use "Y" cords from the audio output jacks them and feed the outputs into the Fossi amplifiers. In two set-ups, I use the sub-woofer outlets to drive powered subwoofers.I also value and use the USB inputs for music not on Amazon. These amplifiers have been bullet proof and sound great.I thought I had a problem one time and contacted their customer service. I got a quick polite response that helped me find the problem elsewhere in the set-up. I came away very pleased with their support. I remain a very happy user.

The hype is real folks, I have been seeing cheap audio man or budget audiophile reviews for years that raves about anything dirt cheap that Fosi audio makes. I do have one of those cheap chinese tube apps that lacks a sub out. Recently bought a deal on a good subwoofer and I need to build a 2.1 system for my home office. The home theater receiver have funky responses on bass so I needed a dedicated stereo amp for my build, and this amp is so well reviewed and within anyone's budget, that I had to give it a try. Thank god I did, this is everything I need, it is powerful enough to drive desktop speakers, and very good for a powered sub. The sound is crystal clear and punchy, does not sound cheap or lacking any power whatsoever. For anyone that are crunching on a budget, get this little amp, I'd say you will have to spend at least 3 times what this amp cost for the next best thing in line.

Due to money constraints I replaced a Emotiva TA1 (needs fixing) with the Fosi I only needed the one input for my Cambridge Audio DAC Magic200M and the sub out for my Elac sub. Hooked up the unit and even with the bass controls all the way down needed to lower my sub volume. I am pleasantly surprised the sound is clean, tight, detailed but is volume picky and recording picky. I have a near field setup and don't play loud these days, especially in a small studio apartment. I have played MP3, FLAC, Hi Rez files of Pink Floyd, Porcupine Tree, Bad Company, Poets of the Fall, and Rainbow so far and sound damn good. Adjustments are literally made for each recording but that's fast and easy. My DAC is 500 bucks, speakers are Focal Chorus 706 bookshelves and my cabling is decent for sure. I doubt Ill have to upgrade again after I fix the Emotiva I may sell it

Cool product

I ordered this unit based on multiple positive YouTube reviews. It arrived same day from Amazon, and properly packaged. It took literally 5 minutes to set it up. It connected/ paired to my Motorola cell phone's Bluetooth with no problems. The sound quality streaming YouTube Music via Bluetooth is excellent. The sound quality playing CDs through the RCA physical connection is much better than I have ever obtained using my 2000s era giant tuner amps. The sound was further enhanced adding Micca MB42X Gen 2 bookshelf speakers, and an older Aiwa subwoofer. I bought this amp partly because it is so compact so I guess I shouldn't complain that as a result there is not much space for connections on the rear. There is minimal space between the outputs to connect passive speakers, you have to be extremely careful to avoid the cable ends touching the wrong terminal. I solved this with a small piece of insulation tape on each connector.The only thing I "miss" is having a remote for volume and source control.As you can probably tell from my description I'm not an audiophile, I honestly don't understand what half the audiophile reviewers are even talking about. However I've been buying consumer quality and better stereo equipment for 50 years and I appreciate the quality of the product and sound that this little amp-that-could represents.

The Fosi BL20C 2.1 amplifier form factor is small and compact. It conveniently fits nicely in a variety of different locations. The case is solidly built metal. The control knobs rotate smoothly with stepped detents. It fits nicely just beneath one of my monitors.Audio Performance Impresses. The amp power pumps out the loudness DBs upon demand. I run with the amp cabled directly to my PC. I bought this amp primarily for listening to music. Depending on the file format type, quality of the file source, and media type, the sound bass and treble defaults can vary quite a lot. The BL20C allows the listener to custom tailor and tune the listening experience, based on preference and the variable sound source.I'm running a pair of Klipsch R-41M bookshelf passive speakers, along with a powered subwoofer Polk Audio PSW108. Both are 8 ohms. The BL20C allows me to custom control all the speakers from a single control source. I found 1st setting the PC OS 'sound' level at about 80%, then secondly tuning the amp bass/treble control levels to the best front speaker sound, then 3rdly setting the independent active sub bass woofer volume level and low pass filter level. After this, I only needed minor amp control bass/treble adjustments based on the music song and source.Just to see what my system was max ultimately capable of, I set the PC OS sound output to 100%, set the BL20C amp bass/treble controls to the middle position, played a musical song from a music file source that I had ripped from CD, then cranked up the amp volume gradually to max. It was very loud and clear. My speakers are rated for the amp wattage power output, so make sure your speakers can handle the Wattage output.My next BL20C test with the Bluetooth functionality. I found if I simply flipped the front panel switch to "BT/USB", the device started broadcasting a BT signal. My mobile device instantly recognized the signal. I added/accepted the BL20C amp device to my phone. Playing some songs from my mobile device, the BL20C received the music stream from my phone fine, then outputted the audio signal output to my speakers. Considering the music source was coming from a phone, the music quality, volume, and adjust ability was impressive.I still haven't tried out U-Disk features yet.The Fosi BL20C 2.1 amp accomplishes what I set out to do. I am certainly enjoying it. The interface versatility is definitely a plus.
