I have the Enyo and did the firmware update and WOW what a difference for the better!
After the update was done I played some music and was extremely disappointed. The next morning I woke up and turned on the amp and music started playing right away. I had forgotten to turn off the streamer the night before, and the Enyo I usually just leave it on.
Anyways, I turned up the volume and was flabbergasted. I listened for a short time and all I could think of was wow things were sounding extremely good. I guess there is a short burn in period.
Well, its been a few days now and I am pleased. Prior to the update I preferred listening with the OS mode engaged and with fast roll off. Today however I like the DAC in NOS mode. The soundstage is immersive, robust, has better clarity and depth. Imaging is cleaner, and defined. Still retaining its warm mid sound that I like about this DAC. I’m hearing more of the bass with better articulation and more punch in the mid bass.
I still like OS mode with fast roll off and look forward to trying it with slow roll off.
This update is fantastic. I find my head bopping to the music constantly now. I don’t know how they did this but kudos to all those involved in this project.
