Hi all, I currently have a Topping DX1, and am using it only as a DAC. Chain is currently DX1 --> SRM-700S --> STAX SR-X9000 headphones. I am wondering if there will be any audible difference if I upgrade to higher model in the Topping lineup (can be standalone DAC or not). I'm open to other...
topping has various amps that are known to have higher than normal probability of failure. In one occasion (L30) they even recalled one of the models, and in that particular case, that’s due to the op amp is failing. In other occasions (such as their speaker amp) it’s also due to the op amp overheating failure as they seal them in modules.

Topping's specs---750 mW @ 600 Ohm or 1500 mW @ 300 Ohm, THD+N < 0.1%---translates to 21.21 Vrms (60 Vpp), THD+N < 0.1%. The difference between 19.46 V and 21.21 V is 0.73 dB, right at the edge of JND, which means it is unnoticeable by humans outside of the best controlled lab tests. Not a difference I'd worry about.
