Is this going to be better than Topping A70pro ? I have it, i like it but it's concern about quality issues, I already returned after 9 months a faulty unit

H400 seems pretty well built.

I think so too but there are so few reviews and feebacks, I'm wondering if it's also a trustworthy brand

And It's here today, way better than topping, the case hardly gets warm, easy menu and display, and well extremely powerful, I didn't need to use Hi with any headphone and track. My first day impressions are just WOW

I just purchased one of these from someone in South Korea, and I'm having it shipped to the UK. It will not include a UK power cable, does anyone know what kind of cable I can use and not blow this thing up?

The H400 has a universal power supply inside, so no need to worry about the wrong mains voltage.

It uses a standard C13 connector, same as any PC for example.

I just got my H400. My H300 is able to get my Moondrop Cosmo's louder than the H400, have I messed up something? Both are using the same DAC, same 4.4mm balanced cable to the headphone. I've tried different gain levels with each device. I have no idea what is going on.

From the manuals:
SMSL H300:
Balanced...................... Low(-6dB) , Middle(6dB) , High(24.5dB)

SMSL H400:
Balanced.................Low(-5.8dB) , Middle(6dB) , High(20.4dB)

Does this mean the H300 is more powerful than the H400?

Directly from their product pages:

H400:

Low and Medium gain are identical, but the H300 has 4dB more gain in High.

More gain=more volume.

I see, so in what way would a H400 be better than a H300? I can see that it has 15W of power at 16ohms vs the H300 10W at 16ohms, does this mean anything if the H300 gets louder anyways?

The H300 can amplify more than the H400, but will distort sooner when pushed hard.

Gain dictates loudness, rated power dictates headroom.

If your sound source (CD player etc) has low output voltage, then a 1W 30dB Amp may well play louder than a 30W 20dB Amp.

But given high enough output voltage from your sound source, the 30W 20dB Amp will be able to push your headphones/speaker to higher loudness while retaining clean playback.

Whats the difference between using low or medium gain and adjust the volume more compared to just setting it high with lower volume level? Is high mode distort more or?

The difference is that amplification is higher for the same volume setting. For the same output level, noise is thus higher. Set it to the lowest gain that produces enough volume.
