Making further progress, TOPPING’s new flagship amplifier will be launched in late May!

Some feedback?

I talked to him Thursday night, the speakers and stand arrived about 8-10 day ago, the amps arrived on the following Monday, the mixed up the order, he got one black and one silver, the sent him the replacement black one, sent him a UPS call tag, the silver one was sent back. Other than that, he said they seem to working great,

Can anyone point out to this ASR review? I couldn’t find it here. This guy reviewed it on amazon and mentioned he bought it seeing ASR reviews

It hasn't been reviewed here yet, the Amazon "review" shouldn't be taken seriously

Was it reviewed on ASR ?

No

Was it reviewed on ASR ?

He probably means he saw it here and just states the full site name.
I'm unfamiliar with Amazon reviewing system so I don't know if that "reviews" are legit.

They are just user (buyer) reviews.

 

[Sokel]

Yes,but are they really buyers?
Cause an incident blowing up speakers is not a review,is a horror story.

I wouldn't believe anything written there without solid proof.

It shows verified purchase tick next to the review. So the user indeed had bought this. It’s the only review available until now, and it’s not positive. This is bad for the products reputation even before ASRs review which is the go to place Topping. He mentioned ASR that’s why it appeared in my search. I searched Topping b200 review and this showed up first.

And there are also user-supplied "reviews" on ASR, so it is easy to see how someone might take such initial user reviews (and the well-reasoned prelaunch comments) as the basis for a purchase decision, even if it is not yet an official ASR review.

Imo, you can't trust individual Amazon reviews at face value, mainly because you don't know if the person knows what they are doing or what they are talking about. When you see a consensus across multiple reviewers, then I think it's safer to question stuff.

For example, who turns expensive electronics off via the power strip?

I do. If kit is not designed to be reliable in this situation it is not fit for purpose.

That's not a great idea, for a none trivial piece of electronics. Devises have power buttons for a reason.

I do, and even in that case it should not pop and damage speakers.

Again, power failure can happen in lot of Asian countries all the time, so this is made only for people who are in Europe or US?

some areas of US also have frequent power outages.

There is a big difference between a power failure and the equivalent of pulling the cable out of the wall.

flipping a traditional light switch, or pulling the plug out of the wall is for all intense purposes an instantaneous event.

A power outage is almost never instantaneous, because of the complexity of the power grid. About the only time a power outage is instantaneous is when the line is cut between you and the last Transformer in the chain.

However, the above glosses over the underlying intent of my initial comment. Your signal chain should be powered on and off in the appropriate order.

Plugging everything into a power strip and flipping the switch is relying on luck/hope. Your betting that every piece of gear in your chain, regardless of manufacturer has redundant safeguards. Imo that's not a bet you should take regardless of who manufacturers your gear.

This knowledge seems to be less common in the consumer space than it used to be. In the production space it's more widely known and gets braught up more often.

For example:

Proper Power Up Sequence Explained

For some, which gear to power up first is common sense. Others couldn’t be bothered to pay attention to such trivial details. We’ll go over the proper power up sequence here and explain why it’s important.

carvinaudio.com

This is why power sequencers exist, and some gear comes with 12v trigger ports.

The B200 is a mono post amplifier designed for music lovers with the advantages of high power and low distortion to provide users with a pure listening experience. As an NFCA discrete power amplifier, it breaks through the traditional performance limitations and significantly improves the noise control and reproduction capability.B200 has a surging output power of up to 200W, which is suitable for all kinds of large speakers and provides two gain options to flexibly match different needs, with a dynamic range and signal-to-noise ratio of 145dB, THD+N<0.000075%@4Ω5W. B200 can be flexibly matched with TOPPING's decoder to realize zero-distortion listening experience; it can also be matched with Pre90 preamplifier or TOPPING's headphone amplifier with preamplifier function to form a high-power combination set.

What's the difference between that an class D? If I jump ship from A/B amps, the B200 has to be on the short list, but I don't know enough about that tech.

It's nothing to do with class D at all.
The LA90 and B200 are both class AB amps, so they are both linear.
NFCA is nested feedback composite amplifier IIRC, which is the negative feedback architecture used to achieve that linearity. Also used on the Pre90 I think.

Hi,
Is the Amazon price USD 599,— for a pair or for a single Monoblock?
