So got the K5 Pro to compare against the Sabaj A10h to see which one was better with the he400se. It was my intention to replace the A10h as I felt it was nice sounding, but lacked the power for the 400se.

I'll need to give my ears some adjusting to the FIIO before giving my verdict, but I do prefer it to the the A10h. It is slightly more powerful, but the main difference is I think it pairs better with the 400se sonically as it's slightly airier, thinner and a touch brighter. This helps bring out detail and soundstage in these cans.

Where it really improves is in the gain increases. On the the 10h the low setting is pretty useless for most headphones and power hungry IEMs, whereas the basic setting on the FIIO is very good. On highest gain the FIIO is slightly louder at full gain (still not comfortably listenable like the A10h), but the volume from 0-100% increases more accurately, in the A10h there is a big step up quite high on volume.

BUT the A10h is a fuller sound. It is smoother and a lot nicer with vocals. They're also a little more weighty in the sound. Sooo, they're actually a nice companion set with the k5 pro. I think I'll keep both .

Some questions...

When I hooked them both to my SMSL Sanskrit 10th ii to compare, there was a noticeable difference in sound from my 400se when I used Composite In (from my TV), than when in USB mode (from my PC)? Is this normal?

Even tho both are very silent, the k5 pro has this ever so low electrical, buzzing sound which I hear when no music is playing. This buzzing goes away when I touch the housing. From reading it sounds like something to do with 'grounding'?? The two plug sockets in the wall are pretty heavily used (TV, Xbox, SMSL DAC, laptop, and charges devices from the USB slots). I connected the FIIO into its own socket on the wall but made no difference. Is there a fix?

I should add, the k5 pro used as a DAC/AMP is nicer with the 400se. The ESS DAC seems to pair better than the AK4993 in the SMSL. This will be down to preference. Slightly thinner, airier sound of the ESS Vs slightly bolder, but still detailed sound of the AK.

Both combos are great to test and use with other IEMs and HPs

You might be hearing the Power supply noise from the K5.

Compared to my AKG K712:s they sound ''lifeless'' and too sharp, hurts my ears.. Would any EQ settings help with this?

En comparación con mi AKG K712:s suenan ''sin vida'' y demasiado agudos, me duelen los oídos. ¿Alguna configuración de ecualización ayudaría con esto?
Try this on:

Preamp: -6.2 dB
Filter 1: ON PK Fc 15 Hz Gain 4.9 dB Q 0.60
Filter 2: ON PK Fc 39 Hz Gain 1.7 dB Q 0.61
Filter 3: ON PK Fc 242 Hz Gain -1.7 dB Q 0.75
Filter 4: ON PK Fc 883 Hz Gain -2.8 dB Q 2.05
Filter 5: ON PK Fc 1888 Hz Gain 6.2 dB Q 2.14
Filter 6: ON PK Fc 1304 Hz Gain 0.2 dB Q 2.14
Filter 7: ON PK Fc 3158 Hz Gain -0.8 dB Q 5.28
Filter 8: ON PK Fc 6596 Hz Gain 0.2 dB Q 1.48
Filter 9: ON PK Fc 11278 Hz Gain 0.9 dB Q 1.62
Filter 10: ON PK Fc 20143 Hz Gain -5.6 dB Q 0.28
