I travelled a similar path to you @FLTWSI bought my first outboard DAC in 2016, it was an Oppo HA-1. A few months later I bought Yggdrasil 1. Done. It just sound so right I was not gonna' burn hundreds of hours to find that last 3 percent of imagined superiority in another brand.
Then I bought a Yggdrasil 2 and upgraded the 1.
I'll wait until I read some feed back on the latest upgrade to USB (or is it HDMI). As I'm CD only not sure how much of a benefit it would be to me to upgrade again.
I bought an Yggdrasil 1, upgraded it to A2 ( and USB 5) and have since added Unison USB board myself.
I don’t use USB input at all, but will do so if I buy the new Schiit CD Transport.
I love the sound of my system with Yggy A2 at the heart of it and certainly won’t be looking for another DAC.
