Ottimo suono !! Qualità ottima 👍

I had a few requirements when looking for a Bluetooth receiver:-good sound quality/signal conversion-doesn't make any annoying sounds when connecting-doesn't automatically connect to a device without prompting-good rangeAfter using it for a couple of weeks, I can say this checks all the boxes. Unfortunately it's one of the most expensive models in it's category. But when I researched it I didn't find anything else that suited my requirements.The setup is easy. Mine is installed inside an enclosed cabinet under my TV, yet it doesn't seem to affect the range. I can go upstairs without breaking the signal. Good product.

Buena calidad de sonido incluso directamente desde la salida RCA del propio aparato, pero si además lo correctas a un DAC externo de calidad puedes mejorar el sonido notablemente. Yo lo tengo conectado a un Musical Fidelity Trivista 21 y suena excelente.A destacar la facilidad de uso, no hay que estar encenciendo y apagando el aparato, una vez lo conectas te despreocupas, solo tienes que conectarte y funciona directamente. Una vez te desconectas el aparato queda en standby y listo para volver a usarse. Hacia tiempo que no compraba un aparato tan bien construido y pensado. Lo recomiendo sin fisuras.

Having experienced much difficulty over the years with bluetooth, I can say all is finally solved with the Audioengine B1. Set up is reassuringly simple and painless. Bluetooth connection is highly stable - no stutters, gurgles, drop-outs. Sound quality was a particular priority for me, and I can say that the onboard DAC performs very decently, feeding a satisfyingly well-balanced and detailed sound into my 1980s Kenwood stereo receiver. Presentation is warm and engaging - very listenable for general streaming, movies, Youtube etc. Sound stage is a little flat, and HF and LF extremes are rounded off, but only compared with much more expensive units. For critical listening, I send B1's optical out into a Chord Hugo 2 and Jungson JA-88D amplifier. Here the results are amazing. Indeed, I have trouble telling the difference with hi-res files played over a wired connection. If you have a really good external DAC, I think you will be pleasantly surprised. B1 is an unassuming looking little unit but it is well built. I'm loving it.

---------------------------OVERVIEW---------------------------Audioengine's B1 Bluetooth Music Receiver is the affordable, simple wireless home audio solution we've been waiting for. When Apple's AirPlay debuted, with its relatively high-fidelity wireless audio, it was exciting. Bluetooth, which lagged behind in sound quality, eventually caught up and arguably surpassed AirPlay, which would sometimes stutter from network hiccups. Bluetooth, not needing any extra hardware (like a router), is far less likely to stutter, so the final piece of the home audio puzzle is a Bluetooth receiver for high-end musical tastes.The aluminum case of the B1 reflects traditional Audioengine design and the high-quality components and audio fidelity are typical of Audioengine's commitment to great sound at affordable prices. The Audioengine B1 continues to close the gap between your computer music and home hi-fi and even if you're not an audio enthusiast we guarantee your music will sound better!The audio quality of most Bluetooth products isn't usually very inspiring and their limited range can be frustrating. The B1 solves these problems by implementing the aptX codec, which is a high-quality audio converter designed specifically for audio. The B1 also has special circuitry and a precision-tuned antenna to extend the wireless range, providing much more versatility than other Bluetooth receivers.Upgrade your Bluetooth and breathe new life into your audio system. You already have Bluetooth on your tablet, computer, or iDevice, so get more out of it and experience stunning audio with the Audioengine B1 Bluetooth Receiver including aptX, 24-bit upsampling DAC, and extended range.---------------------------WHAT'S IN THE BOX?---------------------------- (1) B1 Receiver- (1) RCA audio cable (3ft/1m)- (1) Power adapter with detachable cable- (1) Microfiber bag- (1) Setup guide---------------------------FEATURES---------------------------- Easy setup, connects in seconds- Plug-n-play, no software to install- Superior sound and extended range- Streams audio from any media player (iTunes, Amarra, Youtube, etc.)- Connects to any music system with an audio input---------------------------SETUP---------------------------1.

Wireless audio has improved by leaps and bounds in the short space of a few years, and the Audioengine B1 Premium Bluetooth Music Receiver is possibly my favorite device to come out of this high-fidelity revolution thus far. It solves the problem of shaky wireless home audio streaming, and it never degrades (and often improves) audio quality. Improvement in Bluetooth technology is the real hero here, but Audioengine takes it a step further and adds a top-notch DAC, which results in a top notch audio accessory worthy of our Editors' Choice designation. While it's expensive compared with the Apple AirPort Express, it does exactly the job it's supposed to do, with solid, reliable resultsThis thing performs exceptionally and is just bliss for wireless music.---------------------------VERDICT---------------------------After using the Audioengine B1 for several weeks, I didn't find anything wrong about the product. I didn't encounter any hiccups or degradation of sound quality even when the receiver is farther from the source. This small aluminum box is simply a "magical instrument" that would easily replace those long audio cables, connecting your source and speakers, without any loss in audio quality. This is simply a great wireless Bluetooth DAC, and you really can't complain about its price. I've seen wired DACs from other companies that are priced higher than the B1, and they probably offer the same audio quality.Here is how I rank the adapters I test, from best to worst;BEST:Audioengine B1 Premium Bluetooth Music Receiver - $189GOOD:Philips AEA2000/37 Bluetooth Hi-Fi Adapter/Receiver (Discontinued) - $28.99Logitech Bluetooth Audio Adapter - $29.99OK:HomeSpot NFC-Enabled Bluetooth Audio Receiver - $29.00WORST:Amped Wireless Long Range Bluetooth Speaker Adapter - $55
