the preamp sounds really good when it works. unfortunately Bluetooth stops working after 1,5-2 hours. the blutooth does not work from the PC with win 10. i do not find any support. there is no manual at all, not even on pdf, you must find out everything, how to pair the devices. fortunately my ios devices work with it. over usb the sound is not so good, not better then my realtec built in sound card. i suspect that the bluetooth chip is located under the tube, and overheats. i wold be happy to consult to anybody, this would be an excellent device tithout the bluetooth breakdowns.

La rifinitura è ottima funziona tutto anche se all'inizio il Bluetooth faceva i capricci, poi è andato bene,. Per apprezzare la qualità del suono deve funzionare un po' diciamo che si deve rodare ma poi è ok.
