It seems that you are referring to my post where I used this exact word. For some reason you took it out of context, because I was talking about those who can return their working units and get a refund. Don't really know why am I saying this twice but somehow you became upset so maybe one more explanation will help.I think that most of the users commenting ''you are just overreacting, the seller is gonna refund your broken amp so stfu'' are missing the real concern of many people inside and outside this forum: the failure that this amp is capable of is potentially dangerous not only for you expensive headphones, but for your ears too. The pop that killed my headphones was really really loud, and I was just lucky that I was not wearing them.
This is the driver that exploded on my headphones, tell me if you would be comfortable knowing that this may happen while you are listening to music.
All of this situation would not be this big of a deal if the problem was that amps under warranty are dying, nobody cares about that, but losing gear and potentially risking your earing is something people (mostly outside this forum, where eveyone seems fine with that) are simply not accepting, ask most resellers how many requests of refund they already got.

It was the other part I bolded, came off to me at least that everyone seems fine with possible hearing damage on this forum, seems like a blanket statement on this forum. Did I misread that? If so, my apologies.I specifically said "the users that comments x", I don't understand how this can be a blanket statement.
This forum is full of helping and understanding people, and I replied only to the "you are overreacting" crowd, there's no need to feel personally attacked ¯\_(ツ)_/¯

The first quote I have not read anyone here post anything close to, who is telling others to STFU about this?
We are not overreacting, we just feel uncomfortable with what I've paid for (considering Schiit stuff is out of stock here from the official retailer as well), and I'm even more worried when I see that there are people who say that they shouldn't be worried because there are just a few cases and that maybe it won't happen because it could have been a failure opamp or buffer lot. Yes, I'm a bit angry with the peoplePeople who can return their units and get the money back are overreacting more than anyone else. I live in a shithole and aliexpress is my only source of this type of electronics. To send a parcel back to China is a big hassle, unreliable and costly. If it will reach the destination at all.
Just return your amp to amazon buy something else and stop worrying.
This, and they wouldn't even reimburse an otolaryngology check if a pair of IEMs explodes in my ear canals, not that this will strictly happen but I'm afraid personally.There’s a big difference between buying from a domestic company that’s committed to replacing both the amp and the damaged headphones and one that requires you to ship the amp halfway across the world and won’t reimburse consumers for damaged headphones.
Most of us are using HPA mode primarily, so yesStill not understand if I could have problems or not in HPA mode
But the problem, as I red, does not affect only PRE mode?Most of us are using HPA mode primarily, so yes

That's why I never buy from Aliexpress and that's why I prefer spending a bit more on something that I can easily return.
My mom always says: "

Anyway, if people are ok with keeping a unit that "you shouldn't worry about", they're free to keep. I care about my hearing and gear.
My Liquid Spark blew out yesterday. I turned it on and the power LED started going on and off very rapidly. Then smoke started coming out from the rear of the amp. I didn’t change anything from before it was working. Still was hooked up the same way. Has anyone had this problem with their Liquid Spark? Thanks for any replies.
well, ok, I see ratings on the 6120A2 for example stating that the chip is rated at 2000V, every component is ESD rated, but what I'm trying to say is that the ESD test should be performed also on the final product assembled. An ESD gun should reach without problems 25kV and above...In house testing and out sourced testing are different. We got ESD and all other parameters tested just as regular electronics. However this is special case. Hence needs different test. Nothing is even confirmed. In real world 20kV-50kV is possible. But in the standard it's 4kV. And the components are rated ar 5kV. Everything upon now is just guess. It's better to be safe than sorry.
@Giangi71 an user reported the malfunction also when used as a pre.Hi John,
I had one for 4 weeks until ESD killed it.
It was running as pre-amp between Cambridge Duo phono pre and the Cambridge Azur 651w poweramps. Lovely sound, so much better sounding than my Yamaha 3080 as a preamplifier.
I had a fleece shirt on and when I touched the L30, the ESD Lightning from my finger caused the loudest bang. My Kef speakers would have been gone, if the power amps would not have went to protection mode. I live in Germany and the Unit is still on the way back to Shenzhen since 6 weeks and I’m waiting for the refund. The L30 was still able to operate but now with a massive channel imbalance. I remember that this symptom was reported by Amir or wolfs, during an early pre release test.
I loved the crystal clear sound of it and replaced it with a save grounded chassis Topping A90.
cheers
S.
But how many people have reported that issue? Either as hpa or pre mode?@Giangi71 an user reported the malfunction also when used as a pre.
mainly the fault happened when used as HPA mode just because is the most used feature of the L30.But how many people have reported that issue? Either as hpa or pre mode?
I saw that, but that does not mean I will look at my L30 in a different way.It's not like we want to become deaf either, we are just saying that this could be indeed a problem and we are also waiting for an answer. That being said, please read what @PSO has written about Schiit and Labs and the quote below.
My guess (BUT IT'S ONLY A GUESS) is that at this point is not an ESD problem or something like that. If it was something ESD related, it shouldn't leave such burned marks on the pcb, specifically on an opamp. Maybe the static discharge triggered the problem, but for me it's something that has to be related with the feedback circuit. In particular, something related with such a low output impedance, when 6120A2-based circuits are known to be stable with an output-Z of 10 ohm. Even the DX3pro v1 reported a similar problem and the v2 was corrected with an higher output impedance.I'm not really a hardware guy but I find it interesting how can amp can destroy headphones. If it were software there'd be any number of checks you could do to stuff numbers getting too large. If it's related to static, is it possible the large voltage is making its way into the input of the amp and the amp's going "better amplify that - no way of telling it's way outside any sensible input voltage level"? If so, is there any way of stopping that?
