I heard the Wyred4Sound 10th anniversay DAC with their top of the line mono amps driving the great KEF Reference 1 in a good room. It sounded fantastic. However, I still remember the Resonessencelabs Mirrus DAC played (purposefully) on low priced 10 year old speakers and a protoype amp. The Mirrus was something special that still stood out in my memory after all these years. The Resonessencelabs guys wanted to show the capabilities of the DAC on not so great speakers.
Not saying the Mirrus is better than the Wyred4Sound , since what is really "better".
