post #10471 of 20229
Hmmm I've been using my he400 and Schiit MM stack for 1 1/2 months now, loving it with no issue. Yesterday I was using it and all of a sudden after 30 mins. The magni shut off. I switch it off and turn it back on and it worked fine. Any idea what's going on here? I listen to them around 9 or 10 o'clock and I check to make sure all wires are secured including cup wires.

Think it's an amp issue or something else?

Probably got overheated?

Has anyone tried the FiiO X3 with the HE-400? I'm thinking of getting a portable DAC and the X3 looks really interesting...tongue_smile.gif

If it happens frequently, yes. Heat is the killer of electronic components.

I don't understand how mine could of happened like that.  I have my Magni on top of a glass table with it's rubber feet with nothing around it except my laptop a feet away.  I guess shiit happens.

This makes me wonder...isn't it bad in general to stack electronics like that? That is more than likely the reason of the overheating 

post #10478 of 20229
I guess if the heat is dissipating properly then there's no problem stacking them, mine doesn't run hot. Soundeffect, was the amp on top or bottom? I imagine it would be better ventilated on top.

The top of the Magni has a bunch of holes for ventilation. Put your hand over it , if its overly warm (something you wouldn't want your hand on for more than 3-5 seconds) than its overheating and you need to provide better ventilation otherwise you will prematurely kill it. Make sure you do this ONLY after a long listening session so you get a good idea of how hot it can get.

 

Schiit , I'm sure , makes it work within certain temp range. Fire them off an email if it concerns you , Schiit has legendary customer support.

Also the new Daft Punk Album (streaming for free on Itunes) really pushes the strengths of Ortho cans like these. If you want a good album to push them , RAM is it.

Don't know about the Magni, but a friend of mine had the Asgard and he said it gets very hot, to the point that it burns your hand if you touch the chassis. Based on that, I'm guessing that's a common thing with schiit amps. Nevertheless, it shouldn't turn off. If I was you, I'd email schiit.

I have the asgard and if there is no air movment around it and its working for 30 mins+, its simply unhealty to touch it for longer than half a second.

 

I asked around and most people told me its ok, and that i should not worry. 

 

However i did get it a laptop cooler just to be safe. In my opinion, anything running that hot is bad in the long run.

Yeah, that's normal for the Asgard. Its chassis is a heatsink so if it's not getting hot to the touch after a couple hours of use something is wrong.

True, however if the heatsink is that hot, then the internal componenets are running even hotter (hard to say how much hotter, but hotter).

 

Even if the amp can handle those temps, when summer kicks into full gear, i want some insurance.

I guess that's the price for making low cost products.
