Without knowing exact budget, a step up in fidelity and user experience can be found at a very reasonable price with the Eversolo products. They can be used as a stand alone streaming transport, or with their DAC. If using their DAC, then the AMP-A8 is better than the A6, but as a streamer only (bypass the DAC) the A6 and A6 Master Edition are as good as much more expensive streamers on the market - IMO, but the user experience is the best I've seen.
Streaming recommendations
I am looking to add a streamer to my home system. I want to connect it to my Emotiva ERC-4 via the TOSlink. I would control the device via my Fire tablet or iPad 3 (both are pretty good with my Visio Smart TVs.) or my android phone. What is a good unit that is budget friendly?
