The "Soundgenic" (HDL-RA2HF) is an entry-level network audio server developed as a successor to the "RockDisk for Audio," an audio NAS that gained popularity among network audio users. It inherits software technology cultivated by the audio brand "fidata." By combining it with a USB-DAC, you can also use it as a network audio player. It also supports the control app "fidata Music App." With this one device, you can enjoy a total package for network audio. The network player function, when combined with a USB Audio Class 2.0 compatible USB-DAC, supports OpenHome, which is highly regarded for audio applications. In addition, you can enjoy music file playback even without a computer, thanks to features inherited from fidata, such as CD ripping, CD transport, and high-resolution automatic download functions. I am selling this due to equipment replacement. It was operating normally until recently. I will initialize the data before sending it. The appearance has no scratches or stains, but please understand that there may be some minor scratches as it is a used item.
