Hello,
 
When I put gain at +12 , yes it a little bit louder (than the default -6)  but not a lots .... I'm surprise ....
On yours gustard, did you heard a huge difference or not  ?
 
Moreover, I didnt see any difference between moving the first switch (balanced / unbalanced). I dont understand ?

Ok first not a big difference lots of us have +12 for planars. The Bala/Unbala is important,what ever input you are using make sure the switch is the same.
enjoy

I've always prefered 0 gain to all my amps. more dynamic range, less distortion, bass has much more body and vocals are SO much more intimate.
 
With high gain I 'think' I can turn it up louder but actually I'm forcing myself to listen to it louder than I should. On the upside high gain gives me more etchy treble, bigger soundstage and tighter bass which isnt really much...
 
Try switching back to low gain for a while - the only case I can see high gain being better is if your amp is seriously underpowering your headphones (the Abyss, he-6 & LCD-4 would ideally want more power in this case)

Adding gain is like adding digital zoom, where your amp's amplification power is the optical zoom.
Yep all switches down.

On the topic of gain for the H10, there are options for -6 and -12 gain. These are typically used for sensitive headphones and IEMs, correct?

So this H10 sounds like a pretty terrific bang for the buck.  Seeing as it's back on Massdrop for $300, I think I'm going to go for it.  Planning to pair it with an AKG K-702 65th anniversary.  Can anyone recommend a good DAC for this setup, or should I just wait for the X12 to show up on Massdrop again?

While X12 is great, it isn't necessary. The SMSL M8 or Schiit Modi Uber or Multibit would be fine.

Hello,
 
About gain, with my HE-500, at same "volume/louder level", 
 - at 0, I found the sound a little "flat" without relief.
 - at +12 I find the sound more lively, more alive, more depth and meat
 
Gustard with stock amp ops and with about 30/40h of burn.
 
About DAC : I use a schiit multibit ... but well i don't have lots of point comparaison ...
My advise will be, if you want the best money value, to follow the second hand market (and the trade section of this forum).
 
Regards,

It has amazing value for money considering when you upgrade your op amps their ability skyrockets.
I have mine for sale if anyone in London wants to come collect it with the V5i's.

Hello,
 
For my part, I have buy some op amps ( AD797  AD823  OPA627 muses8920)  and I will try them.
But I will  not go for the burson v5 : too expensive for my taste and fiability problems ....
 
Regards,
