SMSL H400

Not sure why Apos doesn't stock the black version.
 
You can set it to max volume or adjust it with the remote or volume wheel.

This is very frustrating, why can't these amps just have an option to select between fixed/variable like the Fiio K11, I'm never confident running an amp with the volume maxed out, just doesn't seem right to me.

The H400 offers a choice of as many as three (3) fixed output power settings.

Why a fixed one if you can turn the volume up to 100%.It's the same thing.And unnecessary extra commutation for an extra button .

Doesn't the FiiO K11 have that option because it's a DAC?
 
Thought I'd post some internal photo's of my H400.

It does appear to be well put together. I have the H300, D6 and C200. They are all nicely made.
 
Got this couple days ago and just waiting it to arrive. Will be using this for hd800s and he6se v2. Anybody have a recommendation on a good dac from d10? Mainly will be connected to my Mac. Maybe E70 velvet?
 
What's your budget.
I'm currently using SMSL D6, Dr2 and a Lampizator L4G5.
I've been using HQPlayer for many years to upsample/convert my 16/44 flac files to DSD512.
All three dacs playback without issues.
 
Forgot to add, I too use HD800s, HE6 se V2 and HE100se.
The H400 drives all three headphones well.

The SMSL D400 Pro would be the obvious choice if you wanted a visual match.
can I use both xlr to connect the h400 and d400 pro and then use usb to connect to mac? Trying to upgrade form my jds atom and d10 and I think these 2 would be a worthy upgrade. I only used RCA to connect my atom and d10 so I wasn’t sure.

You can go Mac -> USB -> D400 -> XLR -> H400.
 
Am I suppose to control the volume on the d400 or h400?
Whatever is more convenient for you.

Though should you encounter hiss, then try to turn up the D400 and turn the H400 down to compensate.
