Does anyone have experience with both the Topping DX3 Pro+ and the SMSL SU6? The specs are identical, and I don’t need the headphone amp. Sound-wise, are they identical? And does the SMSL get hot? I have two of the Topping DX3 Pro+, I like their sound and features, but very much dislike that they get hot (102°F/39°C) in DAC mode. Heats up the other audio components near it. Ugh.
