I have the La Scala in my system now for an audition and it's an absolutely spectacular DAC. I have an MSB discrete for 4 years and this is better by a good margin...I've also heard the Merason (not in my system) and I don't think it compares to the La Scala, different flavors and to me I pick the La Scala all day over the DAC1.
Dynamics and voices, musicality and the overall tone is dead on to the real thing.
