Only other possibility is silver was pre-ordered by some sellers.

My order is for a black one. I think they ordered a lot of black units, and not as many silver units which are sold out, so silver is further back-ordered than black. They could have told you that though rather than blame Topping.
agree with you. custumer comunication is very bad in my first experience with audiophonics.
i´ll try to switch to black version and hope they don´t send me to the end of the waiting line. i ordered the silver version by the end of july.
its so sad....

You can ask them, if you change to black do you get one of the incoming units. Otherwise just order elsewhere, Hifistudio79 appears to have a surplus of stock! Some of the website is Dutch but it's a legitimate seller.
thank you for that info. ill talk to them..

That's the BC3.
It has a 2V output line-out. Which means it can effectively turn most powered / active speakers into wireless ones too ! (just needs a line-out to RCA cable convertor )
I was watching Sandu's review yesterday:
He took apart the power adapter and it's just a transformer in there. There's no fusing, no surge protection, just straight in. Is that was passes for acceptable in China? That would fail certification in North America! Geez, I hope you all have good home insurance.

The transformer should have a thermal fuse if imported into Canada to conform to safety standard. My understanding is that power supply transformers in the USA are not required to have the thermal fuse. The thermal fuse is inside the transformer and cannot be seen unless one peels back the outer dielectric on the transformer.I was watching Sandu's review yesterday:

My goodness, I hope that isn't true. I can't imagine any country saying it is okay to not have input fusing. I hope transformers with a built in thermal fuse is an industrial standard and just hidden in all 100/120/220/240V types. That would be nuts, otherwise.

I started watching that video and he's already messed up saying you can use the p50 supply for it. Not a graet start. I'll carry on watching.
Edit : The rest of the review seemed on point given the measurments.

Don't forget there will be DC power supply circuitry inside the L30 and maybe that will include some safety protection. Also the size of that transformer looks pretty hefty for it's purpose. Perhaps @JohnYang1997 can chime in for you.

Has he tried taking apart the adapter for JDS Atom ? It functions exactly the same as the E30/L30 one.I was watching Sandu's review yesterday:

It is a rather good review but i disagree with his 2 main negatives:He took apart the power adapter and it's just a transformer in there. There's no fusing, no surge protection, just straight in. Is that was passes for acceptable in China? That would fail certification in North America! Geez, I hope you all have good home insurance.
1. Power: As proven in objective reviews on this site the L30 has plenty of power and it seems like he had other problems than the L30 not having enough power.
2. Soundstage: He talks about balanced and unbalanced in relation to soundstage and makes it sound like you NEED balanced because unbalanced can't provide the best soundstage. I think this is a very subjective statement and far from the truth.
I also would like to ask @JohnYang1997 if he has some data about typical power draw of the transformer power supply in OFF mode and in normal use. (I'm using 220/230V)
I'm not sure if I should use a switch connector strip for the transformer or not.
BTW the L30 manual isn't available to download on the website, would be nice if we can have both E30 and L30 manuals as pdf files.
Yeah, I noticed that too and it makes me wonder if headphones just sound more expansive and "better" when you can get more voltage across them. You could say that it means more power is better but I feel like it is just the potential through the voice coil that is helping. I have no proof of this but just something I was considering.
The protection inside the L30 has nothing to do with the protection on the power adapter. Your wall could be on fire while the L30 is nice and protected because the short circuit is happening on the other end of the wire. To be honest, protection on the DC side isn't necessary to protect the customer. It's to protect the L30 if it shorts internally because the transformer will already limit the current to it but not before the L30 goes POP!
Yes, you are right about a short on the wall wart side possibly causing ignition and fire but that's what the house circuit breaker is supposed to protect. I agree it's a weak point in the system but that's how it is in the USA and other countries without protection in the transformer.The protection inside the L30 has nothing to do with the protection on the power adapter.

Maybe someone with more knowledge could enlighten us about that.
But i think the main advantages of balanced is that you get an even cleaner signal and more power and thats about it. With an excellent performing unbalanced amp like the L30 you are way beyond audibility already, more than that is just about peace of mind.
The two main issues i have with these subjective reviews:
1. The lyrical snake oil terms that get used far too often to describe the "sound".
2. The wild switching between many vastly different Headphones. If you test different electronics and headphones it all gets smashed together in your memories.
You could always get some objective measurements without breaking your bank but that wouldn't get as many clicks as the snake oil. Most people are not informed well enough and still believe in that.
EDIT: Here is what i mean: Scroll down a little below the big list to see how they test headphones
