Dans le but de compléter mon équipement, j'ai décidé d'ajouter la version S50 pro plus à mes amplificateurs SMSL AD18 et Sabaj A3. Dès l'installation, l'appareil a accumulé les problèmes. Le premier problème, bien visible, était que la télécommande ne fonctionnait pas. Cependant, si j'utilisais celle de mon autre Arylic, elle fonctionnait parfaitement. J'ai évidemment pris la précaution de vérifier les piles avant de mettre la télécommande en cause. Le deuxième problème, plus insidieux, était l'absence d'affichage sur l'écran OLED censé se trouver sur la façade de l'appareil. J'ai beau scruter, effectuer un reset, remettre les paramètres d'usine, l'écran reste désespérément noir. Je me demande même, en inspectant l'écran, si cette option est réellement installée. Pourtant, selon la description du produit, j'aurais dû en bénéficier. Le son est très bon, mais ces deux problèmes majeurs sont comme des cailloux dans ma chaussure. La confiance est rompue. J'ai donc décidé de renvoyer l'appareil. Désolé ! Review: Trovo che sia un eccellente prodotto - Premetto che questo è il mio primo streamer, però sono un audiofilo di lunga data e utilizzo da tempo dispositivi sia analogici a valvole sia digitali hi-end e posso dire che per la cifra che costa questo Arylic S50 Pro fa davvero bene il suo lavoro di conversione dei dati che arrivano dalla rete oppure dallo smartphone. Non mi aspettavo questa qualità audio. Bravi. Questo è quello che conta per me. Sul fronte dell’interfaccia, posso dire che potrebbe essere migliorabile il seguente aspetto: se non è attivo il wi-fi perché momentaneamente spento, il dispositivo non lo capisce e passa automaticamente in modalità installazione, da cui non è immediato uscire. Problema facilmente rimediabile con un futuro upgrade del firmware. ## Features - 【STABLE STREAMING AND HIGH SOUND QUALITY】: Equipped with aptX HD Bluetooth 5.0, ESS9023 SABRE DAC, Cirrus Logic ADC for true High-Res music.

However, if you want to get the optimum signal to noise ratio out of the system, you need the streamer to provide enough signal level (voltage) to the amplifier sufficiently drive it. As an experiment, crank up your amplifier all the way without providing a signal. Do you hear the hiss? That is the amplifier's noise floor. If you then give the amp a little signal from the streamer (playing the streamer at a very low volume on the app), that same level of hiss (noise) will be present, in a much lower ratio of signal to that noise than if you had the app volume turned up and the amp turned down. So for optimum signal to noise ratio, put the app volume at 100% (or close) and control the listening volume with the amp volume control. But it's obviously more convenient to control the volume using the phone app. I typically set the app volume at about 2/3, and then turn the amp up to the volume level that I want. Then if I want to turn up a song I have room to do that on the phone app. It's a compromise. **Q: Can this device add Airplay to my existing bluetooth speaker?** A: Arylic products currently support AirPlay 1, and will support AirPlay 2 in the near future. **Q: Does it have optical input? There is optical input in the picture, but no optical input in the video and the menu.** A: The S50 Pro + does have an optical input (also a sub output and a trigger output) that an earlier model, the S50 Pro does not have. Unfortunately the Amazon S50 Pro + page shows a mixture of these two products causing confusion. I have the S50 Pro and it definitely does not have an optical input. **Q: can i stream pandora, spotify from 'web browser' on pc? I only see from cell phone.** A: You can enter your device IP in your browser and then you can use our web player to control the device. Arylic does not currently support pandora. ## Customer Reviews ### ⭐⭐ Deux problèmes majeurs *by T***E on 8 May 2024* J'étais en possession de deux amplificateurs Arylic A50 qui me donnaient et me donnet toujours entière satisfaction.
