The Ayon CD-1 and the Raysonic CD-128 share many cosmetic similarities externally.I'm using a modded Raysonic CD 128 L-2 with Dexa D clock.
The mods were done by Chris Johnson(Sonic Frontiers)and the unit was purchased from Walter(Underwoodwally)
I found the Raysonic CD 128 performance to be near that of the Ayon CD-1.
I initially wanted to go with the Ayon but it was just out of my budget at the time.
I've had both units in my system and internally they are quite different yet sonically they share a lot of the same qualities.
I am very pleased with the modded CD 128,however,if they were priced the same I'd give a slight edge to the Ayon.
FWIW-I am also using Gabriel Gold cables between my Raysonic and LSA Signature
