500+ Head-Fier
You’ll find that the Schiit MJ3 is the hottest (literally) amp of all class A headphone amps. Though the MJ3 is great I don’t believe it’s the only pure class A amp in all the amp out there. There has never been a report of any of the class A headphone amps anywhere near as hot as the MJ3.This is a bit of an exaggeration. There were maybe a handful or a dozen cap failures on early production MJ3s, always the same caps. Schiit has sorted this a while ago with a silent revision (new caps). Sure, for a few early adopters sending the amp for a repair/refresh will be inconvenient, but 5 years of warranty is quite generous and offers some peace of mind. Newer MJ3s do not suffer this issue anymore.
The class-A heat question is an interesting one. I have not tried any true class-A amps that do not get hot, so it would be really interesting to know how Flux got around this issue. Better components cannot explain this fully. It is also worth noting, that under the 'class-A' label there might actually be quite a few different designs. It is worth reading Jason's write up about the topic.
Mine too! It is exciting! Right now, UPS says it should be delivered today, but we will see about that. I suspect tomorrow is more likely.
Sure there are amps that can heat up pretty high but those were speakers class A amps and not headphone amps. If anything, the MJ3 is using the same chokes as old school speakers class A if I recall the discussion about it correctly. You don’t see chokes like that in any other headphone amps.
