Thanks for the info Mike, I didn't know that Arcadia is a legacy model since it was introduced in 2018.
I moved to Arcadia (combined with Atlantis server) from MSB Diamond V dac.
The wadax has more detail, better transients and wider soundstage a better dac overall
More info...
I received the Farad Super 3 last week, so just after a few days of playing I really have been impressed. The super 3 is imposing a totally black background and the sound is more detailed but musical at the same time, the bass is better controlled and super fast !!
Overall a great upgrade!
