-looks the Ayon is way better looking then the bland looking cobra.
-The cobra has a nice DAC built in.
-Either has more power then you need so that’s not a consideration.
-I do prefer the el34 over the KT series on the heritage series. both have that option but I know Audionote makes a great el34 amp.
I’ve not heard the Ayon, but I have heard the cobra in a couple systems both with Audionote speakers and they sounded wonderful. if you get a chance to listen to both I would.
If it wasn’t for the looks of the Audionote stuff I would own them again but they cheep out on the looks too much for the price IMO.
What didn't you like about the Sungden? I've been thinking of trying one myself.
