My unit has passed customs in LA and is on the way. However, I am not overly hyped, I have a weird music perception. I like to listen on the lower volumes, and do appreciate quality sound. Have HD700/650, but also enjoy PortaPros ..

Do these guys have any US authorized dealers?

Or the only way to get is from China?

I don't know if they do. You can't even order them in normal fashion .. you email, they email back, you pay, they say "thanks", you wait, 30 days or so later they come ..

Wow. That's very inconvenient. Then if something happens you have to send them back to China for warranty work?

Their shipping charges also seem to be outrageous.

Looking at a Master 9 (only need an Amp, as I have an excellent DAC - Holo Spring KTE w/ Singxer SU-1), but it does not look like doable for me, unless I find something used in US

I bought the NFB-11 after reading about it here and watching a Zeos review. It's paired with HD-600 headphones. I'm very happy with it but have a question. I'm using only the first 90 degrees of the volume dial even though the gain switch is set to low. The volume becomes too loud for my ears after a quarter-turn.

Are there settings inside the chassis to reduce the power output? The device shipped with some plastic bits that might be jumpers (but not like any jumpers I've used before).

First post.

Try to use the "variable out" output in the back. It's cleaner sounding too, the headphone out is very tube-like.

The only use that I know for "variable out" is for speakers. I'm headphones-only, for now. ¯ \ (ツ/ ¯

I'd love to try it out. How do you feed the signal from 2 female RCA ports to your headphones cable? (FWIW, I searched monoprice and elsewhere for a solution but came up empty-handed.)

Yesterday my new NFB-11 from Kingwa arrived, but I have to let it go. (don't ask why

Grab it in the classifieds, if you want to save time and also a little money

Interesting, I've never even considered trying that out. Does that method really sound that different compared to the normal headphone port?

Pretty curious about this, would you or anyone else mind providing some more in-depth impressions?

Variable Out comes out straight from the DAC, without going through the amp.
You can clearly hear the coloration of the amp, when A/B-ing it with the variable output.
The headphone output sounds like Little Dot MKIII, variable out sounds more like Geek Out V2.
Some headphones with a "thinner" sound benefit from the headphone output's coloration, others sound better on the variable out.

Output impedance is the same for both - 2 Ohm

Thanks for the links, Ben!

I am confused, you don't connect your headphones to the DAC output .. that is the hole reason to get this amp, is to drive your cans properly and not bypass it.
