Topping L30 II Review (Headphone Amp)

[skyline385]

This might be a dumb question but I am thinking of getting the L30 II to act as a Headphone amp between my DAC and Speaker Amp so that I can switch between headphones and speakers easily. So my chain would be:

HP : SMSL SU-1 > L30 II (HP jack) > HD800S
SPEAKERS : SMSL SU-1 > L30 II (RCA out) > Fosi BT20A Pro > Polk Reserve R200

I understand it has a dedicated pre-amp function for this but just want to make sure that I am not double amping as I couldn't find much information about connecting passive speakers through a speaker amp to the L30 II.

That'll work just fine.

There's no problematic double amping going on because that's not actually a thing. Just an audiophile myth.

This also might be a dumb question, but when it says "Frequency response: 20hz - 40khz", does that mean everything below 20hz is rolled off? What happens below 20hz?

I'm an audio engineer that's interested in the L30ii for my headphones, but i need to be able to hear if there's any sub rumble under 20hz. It's the one of the main reasons to use headphones, to reference the subs. Am i going to be able to hear 10hz at all and below with L30ii? Is it a slight roll off or a steep one? Or do they just write "20hz-40khz" cos that's what they tested and want to cover their butts?
Cheers!

The frequency response is in the review. I assume DC protection will kick in at some point but its flat to 10hz.

You have 10Hz content? Even 15Hz?

What genre music

You can safely dismiss "Frequency Response: x Hz - xHz" specs whenever you see them in consumer audio. They're completely meaningless.

Here's the L30II's frequency response:
