I meant that just place a big old cpu cooler on top of the amp, it helps to dissipate the heat, so the amp won't overheat.

I understand that. But, unlike a tube amplifier, which fans can actually cool down a bit, the class A solid state
amplifiers will just work harder to operate at the temperature they are designed to work at. I learned this
when using my old Classe Audio DR3 VHC power amplifier from the late 1980's. It was designed to run
very hot and as such could quickly heat up a room. This was especially true for those who used a pair
of these amplifiers for monoblocks (to power the Apogee Scintilla).
Trying to cool these "sonic steam rollers" off by running a fan next to them only forced them to
work harder to stay at the temperature they were designed to operate at. I find that the stock
op amps for the H10 allow the amplifier to run cool. However there are some after market
op amps that do force it to run hot. There are posts earlier on in this thread which discuss
running the H10 with certain op amps from Burson Audio which resulted in the op
amps overheating and damaging the amplifier.
Probably a good idea to read through these posts. Best of luck!

Anyone have a pair of AD823 or Burson V5i-S they want to sell? PM me if you have either one.

Has anyone tried the new Burson V7-s with this amp?

No I haven't. The op amps in my H10 are stock and run cool. I've noticed that many H10 owners like to change the op amps
to those that can run much hotter. In some instances these op amps were not the proper voltage for the H10 which caused them to overheat and to catch fire, thus damaging the circuitry of the H10. I've always liked the sound of the stock H10, so I've never found the need to change the op amps. It's also getting tougher to find nice condition H10's on the used market given that they were inexpensive when new and not particularly well taken care.

From what I have read, the v5 Bursons run hot, but the V6 Bursons are running only slightly hotter.
This is because some kind of voltage issue. So the V6 Bursons are okay-ish. I suppose the V7-s are more like the V6-s, not like the V5-s.
On the plus side, the Bursons provide a better sound quality. Tighter bass, more resolving and open sound.

Thank you!Wishing everyone a very Healthy and Happy Holiday Season and a very Merry Christmas and Happy Chanukah!
Anyways, sooner or later I will try the V7-s in this amp, though I am satisfied with the V6-s at this moment.
Probably just a slight improvement over the V6-s. Maybe after this summer.
Been on the hunt for a good condition h10 for a while. Anyone have any ideas or possibly moving on from the amp?

You may want to check websites like us audio mart and canuck audiomart. Canuck audio mart in particular is a useful venue for locating difficult to find audio gear.
