S.M.S.L B200 Hi-Res Digital Audio DAC Bluetooth 5.1/USB Input Audiophile Bluetooth audio Receiver&DAC Amplifier Title/Artist display 2.33” screen Hi-Fi Audio Stereo Receiver Optical/Coaxial/RCA output

Funciona muy bien. En dos meses que llevo usándolo, no he tenido ningún problema con su uso. El único problema es el iPhone, que no transmite por bluetooth en alta resolución.Recomendado.

Was an easy set up .. To these old ear's the sound stage is surprisingly good. I've used it to feed signal to a number of older amps including McIntosh , Denon, Pyle, plus a mixer and a 15 w FM transmitter .. The latency is also with in tolerance for my need's.. It works as intended and for what it costs it's a bargain..

Forget the audiophile snob "purists" who say analog wired or nothing... This thing sounds good! Super easy simple setup. Nice strong Bluetooth connectivity (can get at least 30ft in my house). Cool nice looking display that shows your track. And for the gear goons... I'm running this through a TEAC EQA-20, to a Sansui 771, and out to A.) Dynaco A25's B.) KLH 17's

Don’t sleep on this. I was using a Logitech Bluetooth receiver before this. This is light years ahead of that in sound quality. I’m amazed. Let’s see if it has longevity.

No matter what I tried I could not get this to output to anything.I tried speakers, computers, laptops, everything I have.It powers up, you can connect to it no problem, it shows it is playing a song on the screen but there is no audio at all from anything.

My interest in this device is in prolonging the utility of an old AVR: at ~15 years of age, while it still sounds great, there’s no denying that it’s a dinosaur as far as new tech is concerned.I tested the B200 in all four combinations of input and output:• BT in, RCA out• BT in, Optical out• USB in, RCA out• USB in, Optical outFor the BT tests, I created a Spotify account and streamed music (AptX format) from my phone). In casual testing, I did not notice any difference between the RCA out (where this device was doing the digital-to-analog conversion) and the optical out (where the AVR’s DAC was doing that job). So far, so good.But what I was really interested was streaming from a computer over USB. First up, I tried it with a 10 year old iMac and, despite multiple attempts, could not get it to recognize the B200 as a sound output device. Next I tried with an 11 year old MacBook Pro, which immediately recognized it as an audio output device (and weirdly as a keyboard too!). Why it worked on the slightly older computer and not the “newer” one is a mystery. I used the same USB cable and they are both running the same version of MacOS. This time the audio source was a flac-encoded rip I’d made from one of my CDs. At first the sound, when using the RCA output was “scratchy/grainy/staticy,” but after reseating the USB connector, the sound cleaned up. Once again, I did not notice any difference between the RCA out and the optical out.I want to emphasize that this was a quick and casual test—a better designed and controlled A-B test might reveal issues that would be a deal-breaker for a more critical listener than I. That said, I am quite happy with the sound quality (and being able to make my old AVR do some new tricks)!Disclosure: I received this product for “free”—in quotes because the IRS requires I pay federal income tax on the retail value.

It seems like these minimalist mini amplifiers are coming in style. This one is fantastic in terms of sound and function, and it definitely qualifies as minimalist. The project box appearance might not be as slick as some of the FX audio, but it has everything it needs to achieve greatness on the inside, the wireless connections are and the sound is fantastic. For size it has plenty of power to drive most bookshelf speakers.I found the decoder entirely sufficient for my needs, but it even has a digital audio out for people that want to use more expensive audio decoders. It has a lyrics display that I haven’t quite mastered and then might be my music is not tagged correctly or some setting needs to be changed, but it’s honestly not a huge priority for me, I like listening to music without having to mess with the computer to do it and this thing is perfect for that

A super elegant way to interface modern streaming services to vintage audio equipment. Easy to set up and works flawlessly. Tons of applications limited only to your imagination and equipment. Well done!
