The Acuhorn LUSSO the pleasure touch the music. A easy to set up use like a gramophone turn on and the needle put on the vinyl. Works with great DHT power tubes that you can plug into the socket. Each audio file format converts to a 1 bit stream to get an analog path. Deliver high-resolution music with HQ players software or devices with music streaming services. Supports imputs USB audio or SPDIF coax.
