In my opinion it was better? What do you call superior clarity, imaging and soundstage but better? The ifi micro idsd Signature is objectively superior to the dx300 as far as SQ goes. That's not even a controversial statement. Doesn't mean the dx300 isn't a good device. It is and it's more convenient than having a dac that you strap to your phone, but as far as SQ, Ifi for the win. As for hiby, the r3 pro Saber hits above its weight too. Comparing btr5, qudelix 5k, and ifi go blu, the go blu wins. But comparing go blu to r3 pro, the r3 pro has better sq. Since it's $200, I would say that's an excellent value proposition... in my opinion.
