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

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!
I think the following post from fs community forum explains the differences well

I received the two Finisar 1318 and the Phoenix Contact GlassFiber which replaced Ubiquiti MM transceivers between the two Melco S100 switches.
The difference was substantial, more musical with lots of detail and super highs !!!! Combination rocks !
I have tried Glass Fiber some years ago with...
I ordered the Finisar 1318 combined with Glassfiber cable, will report comparison with Ubiquiti transceiver
MelcoS100 -> Fiber -> Melco S100 -> wireworld & Sablon -> Nucleus+ - Melco N10 -> Stealth T USB -> MSB Diamond V
