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

[ObjectiveSubjectivist]

so why do it at all

Marketing

Most likely the lowest gain, which is 0 dB on balanced, which is not very useful I guess.
Marketing shows a E70 Velvet as the DAC driving it, and it does 4.2V or 5.0V max on XLRs.
So I guess no one would use the low gain of the amp, minimum medium or high, which would increase the noisefloor some, and make less impressive measurements.

Let's wait for Amir to review it in more standard conditions.

I guess I missed that 0dB or my mind deliberately missed it
So,it needs a preamp outputting 28V (!) for full output ???

Now,that's...

I wanna see what's inside the box. Chips? Discrete?

It's not class D, so no chips, most likely many SMD components for their proprietary input stage and class AB output stage.

Did you see my post? 0dB gain is only on Low Gain with Balanced Input. There are two more gain settings plus Single-Ended has gain at all three settings. I also included rated input sensitivity, and both, input and output impedance.

Yes,I saw it.
But I'm not talking about normal use,I'm talking about the people who will see these measurements and think they will get to use a 125dB SINAD (as defined here on ASR) amp while the measuring conditions are far from realistic.

Well as pretty much everyone else has said, we’ll just have to hope Amir can get this item tested soon.

Either way, I (pre?)ordered a pair in black for myself from Apos, so I will get to see for myself paired to my KEF LS50 Metas and SVS SB-3000 in my medium sized family room. Source is a HiBy R6 Pro II whose balanced output has a rating of 4Vrms.

We wait for some feedback, after you receive it

No you don’t, I only can provide the unacceptable subjective feedback, or plain commentary on if it functions or not. Amir is the one with the expensive testing equipment giving real numbers. Nobody here cares what my ears say because they can’t trust my brain.

I personally don't believe in numbers, i believe in ears, emotions, feelings. So i m still waiting for your subjective opinion. I have same kef speakers

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.

yep,

Equipment
On : Pre-amp (with attenuator completely @0) , DAC , Power-amp
Off : reversed sequence

Hi
Will the B100 be enough for this speakers?

 

[Bleib]

Hi
Will the B100 be enough for this speakers?

Yes, neither go really deep so that helps as well

 

[staticV3]

Hi
Will the B100 be enough for this speakers?

Which one?

 

[Michal]

Which one?

Both.

This study also included some non-believers in measurements.
On page 78 is a quite famous test between some very well known high-end amplifiers published in Stereo Review:

I worked in a store that sold the same Levinson amps at the time, to be honest I wasn't surprised. You would be surprised at your inability to tell properly operating amps apart.

For sure, there are some corner case situations where amps can be differentiated. Like when driven to hard audible clipping, or when asked to operate some Apogee Acoustics Scintillas, or when the bias is massively out of spec, or when you hook a noisy amp to a 100dB sensitivity compression driver. Also if the amp is broken.

Outside of these unusual cases, you need to hallucinate to actually hear amp differences.

Here is a survey of multiple attempts by people to discern amp differences, controlled for peaking, cheating, and lying.

Actual Double Blind Studies

I have always been curious about 'training' for these tests. I saw a visual test that used an aerial pic of a full Rose Bowl, and instantaneous ABX testing was used to compare two pics and seeing if people could notice the difference between them. The subjects couldn't do it. Then, the tester...

Both measurement unbelievers and believers can't tell the difference.

Aaaaaaaaaand this is why I don’t talk subjective around here. ¯\_(ツ)_/¯

It is ridiculous how ignorant and truly misinformed many people seem to be about what constitutes evidence and why evidence matters. Frankly I suspect that the majority of people who seem to be unable to understand this simply do not want to and prefer to be ignorant.

You can talk about subjective experiences, just nobody should suggest that their subjective experiences are anything akin to evidence

Or just do what I have been doing for a while now with other closet-feelers: use DM instead of forum posts to discuss subjective matters.
