dude, you are totally overreacting.
he is concerned about a popping noise that occurs after 20 seconds from turning on and when you shut down the amp. I simply stated that this sounds like normal behavior of the muting relay to me and if he is still concerned, he should contact schiit customer support... lol........?
hey, I mean this in the nicest way possible, but i think you seriously need to be a bit more careful about your tone and reactions to posts. you are kinda coming off as a really overly defensive and you are perceiving posts that are simply a neutral discussion about a topic as criticism/negative feedback towards the product when that is blatantly not the case. no one mentioned the nwavguy 'scandal' or said anything suggesting that headphones may be damaged by this amplifier. we were just addressing one person's concerns. lol!
edit: btw, popping does NOT occur with the valhalla because it does not require a muting relay due to its slow turn-on. All Lyr 1/2 do have a click/thump-type sound after 20 seconds from power-up from its mute relay, which is what I am assuming is the popping sound that OP hears. I am pretty sure what OP is describing is normal behavior and not a concern. However, I never thought that sound from turning on or off sounded like a pop, so perhaps OP is experiencing a different issue which it may be prudent to contact customer support for. lol I don't think any of this sounds inflammatory or unreasonable.
That pop is (fast) DC transiant. With Lyr, the switch delay let the amp stabilize it's DC level at the output to 0. However, it might not have the time to fully come down to - or the change of load (from infinite load to your headphones) might create a small period of instability. With Valhalla, that transiant is really slow, so instead of kicking your driver with DC making a sound (pop), the DC slowly goes up and then down to 0, making no noise. If you want a pop with Valhalla, simply turn on the amp, wait 5 secs and plug your headphones, you'll get one too.
(correct me if I'm wrong on the technical side)
