Why we need to explain what's objectivism and why subjective appreciations are welcome but doesn't mean any proof of nothing?

Maybe a brief fixed post with that concepts clear will be a good idea
If 2 things are objectively the same in what can be measured about their function(s) but I like one better than the other, then that's subjective (the way they look, the way that the controls feel or even simply how I feel about them).
That is my idea of being brief.

That's really brief :-) ... I think the strong concept behind objectivism is to have some way of discrimination about good / bad / average performance independent of your taste, your room, your speakers ... your brain tricks. And we mean good performance as fidelity to the source signal (hifi)

That too!
 
@amirm - I use a switch to turn on/off my stack of amps. Does this retain memory of last use state or do you have to touch the button? Can you try powering it on/off with a power strip or external switch?

Thanks for the on/off update on the review.
I got the B100 monoblocks -sounds great with high impedance speakers btw- and i also use a switch strip to power all hifi stack, and because -presumably- i also hate to touch hifi device buttons for power on or off things -fear of they wear soon-, i got a small 12v 0.2A extrenal smps adapter and modified the conector by a mono 3.5mm jack (for simulate a trigger component, my E50 topping dac doesnt have trigger and i use a passive transformer based line stage ) -make sure positive on tip- with a Y wire and i turn on off both just with the power switch strip for all stack... im planing to get linear PSU for then , sounds great but you know, with LPSU every audio sounds "a little unmeasurably sweeter and more humane the voices" hehehe

Performance was expected and depending the use-case can be adequate.
But is that front plate plastic???Cause it sure looks like it.

Thanks Amir!
to touch it looks like glass? build quality feel to fingers great only is smaller you think
 
Inexperienced SINAD fanboys who have no practical experience of what is audible and are impressed by inaudibly low distortion numbers and ignore things that matter much more for real daily usage like reliability, serviceability, customer support, user interface, internal PSU etc.
Well i would never buy a line preamp "line stage" based on THD meaaurements -i use passive transformer volume control kind desing becasuse i love the circuit topology if you think at it, nothing else could be more transparent and in fact its, i dont care some day they measure it and its the worst measurements line preamp, i will keep my 3 line stages TVC types anyway, 2 for tho rigs and 3rd for just spare, is dificult to built it and perhaps someday is not anymore availble this KIND of line stages- but a power amplifier, obviously if it has lower distortion IT WILL HAVE MORE RESOLUTION DETAIL AND DEFINITION and with my Topping B100 (as much as my 3e audio pffb module based with LPSU diy power amp) actually it is like that. My friends says my "simpler circuit hifi concept" would be more logical a class A amplifier, but class A gets hots as hell and not really more detailed, so y prefer more 3e and topping amps

Are you planning to DIY the linear PSUs or have you somehow found a fully assembled, off-the-shelf linear PSU that fits the B100’s specs? I was unable to find anything that didn’t require jury-rigging the wiring myself and/or had fans (I don’t want fans in the PSU).

Well i found a manufacturer from PRC in ebay who do linear psu and he did for me a custom Linear PSU for LA90 integrated and it was very silent so i did ordered again a custom linear psu for b100 and im not the first to order to him for b100 he said
 
I got B100 monoblocks that are paired in my setup with Elac Vela VF 407 speakers which are 4ohm and Eversolo DMP-A8 output max 4.4V into balanced XLR. I get plenty of power even at the lowest gain setting. AFAIU, Elac Vela's are not the most efficient speakers (88db). Playing at the loudest volume (0db) is way too loud and -20 to -10db is what I use most of the time for comfortable listening. My room is about 30 sq.m.

Can someone explain why many people say that B100 lack power? I'm not an expert and only at the beginning of the audiophile journey.
I was considering buying an amp based on the latest Purifi 1ET6525SA modules, but opted for B100 as they are cheap and seem to be SOTA per SINAD and all other measurements.

Power demands ramp up extremely quickly with larger rooms and sitting farther back, especially with speakers that can reach deeper notes/lower registers because bass production is what truly sucks up power. You happen to have a setup that doesn’t need it, but if you had less sensitive speakers that reach down to 40hz or lower at +/-3dB and sat twice as far back in a larger room, you’d need several times more power.

Power consumption doesn't drop just because a speaker has poor bass extension.

The same power is still pushed into a satellite speaker, it's just turned into heat instead of SPL.

50w is plenty of power but lets say is the minimum for real hifi, the one complained perhaps has like me a passive low output preamp -but i dont care, i trully love how it sound- and/or a low sensitivity (less than 86db) speakers... but otherwise is agreat amp even for me because my speakers are a easy minimum impedance and easy sensitivity mainly. But yeah, hypex or purifi both are( in contrast with anything topping, 3e or smsl) stable at 2 ohm and obviusly are bomb proof and much more reliable... but if you have high preamp output and medium load speaker like you or better, b100 are very good, and you can upgrade the psu if you want something more reliable amd filtering like a linear psu
 
Fascinating.
Im not engineer but im agree with you that obviusly an amp draws more current at low impedances and usually lowest impedances in speakers ar a loweest frequency hehehe so yes "more bass perhaps means more comsuption most of times"

just to add also -many thing i know i learned in this site- someone in this forum said the benefits of high impedance (minimum) loudspeakers are cheaper parts in amplifier and yeah, B100 (specs ">4 ohm") are way cheaper and for same money less distortion (more resolution) than hypex, purifi, benchmark power amps that are all stable 2 ohms but yeah much more expensive amps and not really cleaner THD
 
If Topping made an integrated stereo amplifier with these blocks and a power supply in the case and with enough analog and digital inputs, then they would have the best amplifier on the market...
Well if they put all that noisy things (to make that "integrated digital receiver") (noisy as a power supply regarding EMI to induct noise to line level circuit inside etc, not to mention also adding a dac chips also noisy regarding EMI) in case it woundn't be stellar measuring true power amp that its is (true high end audio is always separates the line stage preamp from power amp and each one with SEPARATE power suplies ... but what people doesnt like is that black plastic (switching) power adaptors but if they came with a that "high end looking" metal case with red power led heavy external power supply (linear) that looks cleaner and luxury course they would like more) but course for 600$ pair you cant not ask for much more and definitelly an "integrated receiver with digital imputs and remote" will measure way worse (due all that swithing electronics and dac chips and remote chips squeezed inside same case that line level) than this stellar true high end power amplifier monobloks separates with better sound than pure class a monoblocks 50w costing more than 5000$ or triode single ended same power same price monoblocks, so again, bravo Topping !!! @TOPPING

@transformer-coupled, that's a lot of conjecture about competent or incompetent integrated amplifier design. You seem to read too much audiophile magazines etc and have absorbed the marketing BS they propagate.

If you know you stuff you will not have any EMC problems and also you don't need seperate supplies (let alone linear ones) etc to obtain stellar specs.
Actually, an integrated amp with everything on-board (phono, line-in, DAC, Bluetooth, poweramp, phones amp) is the best-case for signal integrity and can yield much better specs than half a dozen of seperate specialized units.

Obviously, if you "design" an integrated by clobbing together random building blocks performance might suffer but when someone knows about signal integrity dos and don'ts neither noise nor distortion will suffer from preamp stages, source switching, remote, proper DAC implementation, etc etc.

But that IS what happens more often than not these days.
