I'm using Burson V5 Single for my H10, no heat issue.
Never run this amp more than 6 hours continues.
 
Burson opamp contributed big sound improvement for H10, I tried some opamp. I prefer  Burson.
 
If you want to try, make sure you order the last version of V5 (Single or Dual), V5 first version has some issue

You are talking about the V5 not the newest V5i with the metal can, right?

My second pair of single V5 just died on me yesterday.
There's a clicking when the music played for about 2 hours, and then silence.
Plugged in other OP, everything went back to normal.
 
and yes, my V5s are the new version, just received them last weekend.
and I have installed the heat-sink.
 
So my conclusion is that though Burson V5 probably the best sounding OP amp for H10, but they just don't physically fit for each other.

Do you use them with the H10 case closed or with the lid off?

Did you run at +6 gain, as Burson recommends?

Closed

Yes, +6 gain.

Does that mean it is OK to run -6/-12 with singles only and stock NE5532?

 
 

  Yes, seems this gain setting only affect the dual opamp on the back

 
 

  We did and we found that the at "0" gain and less the dual V5 heat up too much. That is why we recommend the +6 and +12 setting. 

 
V5s should not have problem with gain setting.

I'm still enjoying my V5 Duals in a portable amp, leaving the lid off simply because the V5s are too tall to put the lid back on, but from everything I've heard to date, I think Burson's use of an injectable foam material, surrounding all of the discrete components, in combination with a solid plastic shell, traps all the heat that's generated within.  When the air temperature inside an amp's closed case is greater than ? degrees, the V5 overheats, the sound quality begins to fail and/or the foam and the plastic case begin to melt. Higher supply voltages only increase the internal heat generation of components that are encapsulated within that foam insulation. I suspect the V5 would be far more robust if they would just stop using the injected foam and go back to an open design, like the V4, or at least, stop using the foam and find another way to attach the case to the DIP8 base, having drilled some holes for ventilation. Better still would be an aluminum case, but that would probably double the price.  
 
Meanwhile, has anyone tried affixing small heatsinks directly to the V5's plastic case (or large heatsinks set atop the H10's case, as I suggested in an earlier post, above)?
 
If you search for "VGA RAM heatsink" or "Raspberry Pi heatsink" you can find several that have 12mm x 12mm dimensions (or thereabout) - small enough to affix to the sides or top of the V5 case.  I would sand down the top of the case to make it perfectly flat, before trying to affix a heatsink there.

Bringing down the temperature of the entire H10 seems like a better idea to me - the whole amp would give you more years of service.

Sorry to put a fine point on it but Burson now has these, the V5i-singles. You are talkng about the V5 with the tall red heatsink, right?

Has anyone actually received the v5i model and tested a v5i full boat? I'm interested to read some opinions and if at all possible comparisons to the SS v4 full boat.

My bad. I didn't pay attention to duals vs singles. But it sounds like the amp was at +6 anyway.

I ordered a pair of the v5i's but they shorted me one. Still waiting for it. Not a full boat but soon to be a couple of data points.

Yes, the red one

What combo will you be running?
