  But the Asgard 2 generates heat which rises up to the Modi above it.

Nothing really to worry about. Check this out, as an example of components most likely to be affected by temperature:

3000 hour life rated capacitor?
 
No. That's at 85 degrees C (or 105, if rated that way.) Try 133,000 hours at 35 degrees C, 66,700 hours at 45 degrees C (average temperature of an Asgard 2 case--not internals). Or, about 45 years at 4 hours per day use at 45 degrees C. 
 
Heat is not really a factor, until you get into silly (65-85 degree) temperatures.
 
Bottom line, if we do a 5-year warranty, we expect it to last at least 10. And that's largely governed by the crap lead-free solder we have to use these days. Look up "tin whiskers" for more fun.

I hope that's in degrees C.

 No wax caps, eh?  I'd still keep things as cool as possible.

Tape sunglasses to your Schiit, to keep it real cool :cool:

Thank you for reinforcing what i already knew :)
BTW, love your products. I recommend them to everyone asking.

I hated the switch to lead free solder! My lungs miss leaded solder smoke

 and high-end RCA's with MUCH higher copper content were already a pain to solder with the heat spreading out so fast and lead free solder (at least the lead free solder I've used) makes it more of a pain in the butt.

Irreversible brain damage, developmental delays, hearing loss, miscarriages, abnormal sperm, caused by lead poisoning, on the one hand.  More convenient soldering on the other hand.  I guess it's a tie, huh?

Another quick "it ain't no thang" heat story:
 
When we were in development on Lyr 2, we noticed that the heater transformers ran a good bit hotter than Lyr 1 (about 55 degrees C.) Concerned with their lifespan, we sent one to the transformer manufacturer, who came back to us and said, basically, "This is nothing. What are you worrying about?"
 
"Well, what are they rated for?" I asked. Figuring it was about 85 degrees C.
 
"115 degrees C," the transformer engineer replied. 
 
"For how long?"
 
"Indefinitely. But we have some customers who need more, so we can do them up to 150 degrees C indefinitely with different insulation."
 
Yeah. 150 degrees C. That's 302 degrees F. For a transformer. Wow.
 
Another fun fact: most speaker power amps have a fail-safe at 85-95 degrees C on the heatsinks...and many pro amplifiers run just below that temperature all the time. That's easily 95-105 degrees C at the devices--or about 50-60 degrees hotter than Asgard 2 and Lyr 2.

Who told you I have brain damage?...it was my wife wasn't it?!
Always complaining, if its not about my abnormal sperm its going on and on about my brain damage...well these ends are going to solder themselves are they? Wait, what were we talking about?

Warning stickers are already on your amps, correct? I do not remember

Joining the Schiit family here. Got an Asgard 2 and a BiFrost DAC with the uber analog upgrade. This combo is connected to my computer and drives my HiFiMan HE-400 headphones with aplomb. Very nice gear. Simplistic design (this is a HUGE plus) and very well built. They run a little hot, but heck, it's a Class A amp. If you want an air conditioner, go elsewhere.

Great! Welcome to the club.
