I think mine was one of the hand soldered 2012 replacement models. I wouldn't be concerned buying a new one.Thinking of pulling the trigger on a L30,E30 stack, but should I be worried about broken pogo pins and whatnot?

It happens every time I go from pre to hpa or hpa to pre. It doesn’t change with volume on the amp, usual listen level vs full attenuation it’s the same. With the dac powered off it behaves the exact same
Finally got one (s/n 21xxx)
How do the 3 gain levels work ?
What is the voltage fed to the headphone at -9db, 0db and +9db ?
Can I use the +9db gain on a 32ohm load or is there a risk to damage the HP's drivers because of voltage is too high ?
Yes, my list will tell you.Is there any way to know what is the voltage limit of an headphone ?
They sound the same, they just differ in loudness.And ultimately, which gain sounds better ?
I tought the -9db would have been the one with the best thd+n, but that clearly isn' t the case judging by Armirn's review ... how's that possible ?
What happens at the maximum voltage, does it clip?Yes, my list will tell you.
I meant the maximum voltage of headphones listed in your table.All amplifiers clip at some point, be it voltage- or current-limit being reached.
Oh, so this is your list!Yes, my list will tell you.
That is true (because few people will hear the difference), but AFAIK it's not entirely accurate.They sound the same, they just differ in loudness.

Like said by John Yang (designer of the L30) somewhere in this topic, the L30 offers its best performance at the 0 dB gain position, with the volume knob close to the max. Then the listener can play with digital volume control in the DAC and/or in the audio player.
Gain between L and M is the same, the input in L is attenuated so M is 'technically' the best but even L and H are already exceeding every humans hearing limit.
Oh boy, please don't fight here You asked a question on ASR and we are trying to answer you as accurately as possible, according to the only thing that matters here : measurements. Not ABX : measurements.It is true and accurate because it will sound the same regardless of performance being slightly different (no audible difference).
don’t believe me? Do an ABX. I did and couldn’t hear a difference.
of course your ears could be better than mine

The designer of the amp confirmed this, hence there is no discussion possible, sorry. Like I said, few people will hear the difference. But your question wasn't if you could hear it or not. The 0 dB position with vol knob close to the max objectively sounds better. Whether you or anybody else can hear it or not is irrelevant. Again, we are on ASR here, not on "superaudiophilelove".
PS : Thanks to @solderdude for confirming it BTW. Of course we are saying exactly the same thing. So @Benaudio , please don't discuss this anymore. Thank you.
Yes you should. Actually your whole life should be governed by fear.
Or maybe just take a leap of faith and remember that on the Internet, people who complain on forums are usually the 1% with problems. The 99% others just enjoy life!
Seriously now, there's no reason to worry. Worst case scenario you'll get a refund or an exchange.
I personally have a 3rd amp to buy, and guess what it will be ?... Yes, another L30.
It looks like it's normalHere's a question to L30 owners, do you notice that the amp has a rather large volume pot deadzone from around 3:30 o'clock to the end? To me, even with pure sines, the volume sounds equally loud past 3'oclock or so. Is this the effect of running the L30 from the E30 which can't provide enough voltage to max out the volume, or is the amp designed with this large deadzone? Is my unit's volume knob just monumentally shit?
Not that I'd be running it past 3 o'clock on any gain anyway, just found it rather curious; my old K5 Pro didn't have this deadzone, it instead only activated at 9 o'clock
