I've successfully updated the firmware. Without documentation...what are the differences, if any?
 
We have 2 YouTube reviews now.


 
Does anyone know how many volts it can output at 12ohm?
 
Im just wondering if it can put out more power at 12ohm then the A70 Pro, similar to the VMV P2 but in a modern package.

We need more measurements to say.
SMSL's power sweeps at 16 and 32Ω are not enough.

The power numbers stated in the spec sheet are incorrect and therefore useless.
 
Does anyone know what's up with this amp's grounding port? I'm not sure how or why you would use it.

Interestingly, the H400 simultaneously outputs the RCA and XLR to an external amplifier.
Even if a PCA or XLR is connected.This useful feature is not mentioned in the manual!:)

Meant for use with a powered sub?
 
Is this a joke?The SMSL H400 is the latest headphone amplifier+power amplifier preamp.This is not a receiver or an amplifier for acoustics.

Some YT reviewers have been saying they have used some headphones with a powered sub...for the untz-unts...

I suppose some ppl might also use that setup for movies or gaming?

It is possible, of course, if, for example, the XLR input is to the power amplifier and the PCA subwoofer or vice versa.
 
This thing looks and spec-wise sounds badass. EYES ON THIS!
 
Update: I had not seen this detail on the page before but it is now. It is relay controlled!

"Remember the days of scratchy volume pots and channel imbalance? Yeah, those are over. The H400 uses electronic relays for volume control, ensuring precise adjustments and flawless sound quality at every level. "
