Received the item this past Thursday. Unpacked the box and reviewed the set-up instructions which were easy to understand. Discarded the ethernet cable that came with the 21, since it was not long enough for where I wanted to install it. Had a longer cable that fit the need and set up the 2i with the RCA cable that was included. Installed the Bluos app on my phone and proceeded to finish the set-up. It updated the 2i software. I encountered no problems while completing this.Next day I started ripping CD's using FLAC. After ripping several, I stopped and played back the music. It was very clear, and of high quality. To date I have ripped about 60 CD's. The 2i is not very noisy while ripping, although you can tell when it it changing tracts. I have not made any folders, or playlists, or edited any input yet, so I am not sure how that will go. Overall I am pleased with the 2i.
