I was quite surprised by it. I didn’t really expect it to sound much different to the built-in output of the Cyan PCM unit … but it definitely elevates the performance of that unit, being more resolving and more dynamic and, despite similar (actually identical) power ratings, seems to yield better authority with super-hard-to-drive cans.
I’ve decided to buy one of these to add a headphone amp to my current living room speaker setup. As I will be sitting some distance from the HPA I wanted something with a remote control. I looked at options such as the Burson Soloist but I just don’t need that much power (and heat) to drive my generally low impedance headphones:
It’s likely, but it was not something I made notes on (which suggests nothing stood out doing so, good or bad) and since it was over three years ago that I looked at the Azure I can’t remember any specifics.
