Ayon Triton differences?

I own the first one, now in storage during school time but I am wondering how much different could be the latest generation besides XLR inputs etc,
I am wondering is the original one that I own is turning in a prehistoric item on Ayon line of tritons .
Most of all I would be very interested in hearing sound differences between them from people that upgraded or had the chance to compare them.
I really appreciate any info you can provide me, curious and deciding on my amp in storage.
The difference from I to II was pretty damn good IMO. I suspect 75% of that may just be the difference between the kt-88 Gold Lion reissues and the Black Treasures... Mainly more detail and dynamics.
