Topping L30 Headphone Amplifier Review

[threni]

2006 is lower than 2012 so...yes... get it replaced for free.

with versions below 2012 you have a very small risk it could damage your headphone in case of a failure.
Failures that have been reported so are real.
Do yourself a favor... contact your seller and have it replaced ... just to be sure.

Maybe ask your seller why you've not already been approached. An email to all customers who bought before a certain date surely isn't asking too much? Didn't Topping tell them to?

It is pointless to measure the 2008 version. NONE of the serial numbers below 2012 will have a connection.

ONLY 2012**** serial numbers could be checked just to make sure one has an ESD fixed version There is a 10% chance the wire is not there BUT the amp will not destroy headphones in any case when an ESD pulse destroys the amp.

All serial numbers above 2012 will have the connection and even when the connection is not there (assembly error) your headphones will still be safe.

So with 2012 there is still a chance an ESD pulse to destroy the amp? Is there any way to make them safe too?

just curious, did you have to send them your faulty L30 first or did they just send you a new one by showing them a receipt, serial nr. etc?

 

[Billy Budapest]

90% of 2012 and 100% of newer batch are completely fixed.

Is there still another fix coming in February? Just wondering.

I purchesed and contacted through Amazon uk so they only wanted my serial number and delivery address.

nope

Nope, because there is nothing left to fix.

About 10% of 2012 batch left the factory without the ESD fix.

When you know something about electronics they are really easy to fix. When you don't ... don't worry ...it won't blow up headphones.

Do this ONLY to 2012**** versions that are only missing the ground wiring. The vast majority of 2012 (90% of them) already have this fix.
Every serial number above 2012 is 100% fixed.

My main concern is the faulty function in preamp mode. My marantz PM 410 is just great with my HD6xx and significaly better than L30. I was about to return L30 but i noticed that topping stack E30 + L30 is way better than just E30 on its own in my system. So is it that dangerous in preamp mode that maybe is better to return it? Too risky? What would you do in this case?

It is not dangerous in preamp mode. I'd go ahead and get a replacement if your serial is before 2020 December (2012) but the fault fries headphones. Your gear down the chain in preamp mode is safe.

Thanks for the reply. It is 2008. I will go for a replacement, but in this case would the older units be safe too? Although i already damged it, this info could be useful for some.

OK. I know @JohnYang1997 had mentioned earlier that another fix was coming in February—this time to protect the unit itself from damage due to ESD rather than the headphones.

John stated earlier in this thread that 90% of the December 2020 units (2012 SNs) have the ESD fix and all of them have the protection fix.

I assume you also work for Topping? Either way, your nickname is kind of epic.

I'd disagree. If the amplifer input stage isn't cap coupled there will be serious problems if the l30 dumps its dc rail out the rca output.

OK, cool.

 

[escalibur]

Shenzen Audio will be shipping my L30 before Chinese New Year. It looks very likely that I'm gonna get 'the very fixed' version.

 

[wrigglycheese]

Please don't do that. The above picture already made me very sad.
It's OK to destroy it if your reseller forces you to, but there's no need to display it.

I admit I am not fully keeping up with this thread so stupid question but... Why would a seller force someone to destroy an l30 ?
