Currently, I just use the standard 3.5mm headphone jack to RCA converter when streaming Pandora or other streaming services using my Nexus 7 tablet. I have noticed that one of my favorite streaming stations is now streaming in FLAC. I haven't tried the FLAC stream yet so I don't know how it sounds. I also have alot of music on my computer that I will transfer to the tablet to play. Is this setup going to provide the best sound or can I do better? I've been kicking around the idea of using a OTG cable and some sort of usb DAC like the Topping D20 or a Dragonfly. Not sure if it will work or what kind of results I will get. Any input would be greatly appreciated!
