Topping, SMSL, ... ESD & DC Protection

[metasharp]

Hi all,

I asked SMSL and Topping for my own needs about some products since their documentation wasn't clear to me and got answers from them.

• SMSL SU-9 Pro
• Topping A90 Discrete
• Topping LA90 AB

They all have a proper ESD and DC protection. Feel free to add more info in comments regarding those or other products.
At least I feel more comfortable plugging my Dan Clark Stealth now XD.

Spoiler: SMSL answer about SU-9 Pro

Yes it get ESD and DC protection.

Best regards
