That's not correct. Its peak, continuous and max powers are the same due to enforcement of protection circuit. Actually, in testing, it seemed to allow a bit more peak power before shutting down. But wasn't worth capturing and including in the review.
Does this mean there is no more power for music dynamics?
(Maybe already explained elsewhere in this thread but I must have missed it. There are, after all, some 700 post now.)

Think of it this way: There is a certain maximum voltage the DAC can output, divided down by your volume setting. If that falls within the range of the power amplifier, you're fine.
 
For some systems that may be appropriate. For others, that is overkill. There are numerous factors that affect how much power is needed. Yesterday I started a thread and posted a link to a spreadsheet to do some rough calculations to determine the minimum amount of power a system should have.

Finally got a chance to try a few calculations in this spreadsheet with my setup (B100s driving a pair of KEF LS50 Metas from my listening position based on speaker placement but not even including subwoofer), and only need somewhere from 7-16 watts (depending on impedance I put in, since KEF rates it 8ohms with minimum 3.5ohms) to hit peak 90dB at my listening position. This is way less than the B100 puts out. Again, this is not even factoring the fact that I have an SVS SB-3000 providing the slam--which means all of my real-world testing was lower wattage still than any of these calculations for the measured sound levels.

Why are people so worried about power? 23-52 watts would be needed if I were even willing to listen with 95dB peaks, which I am not. I was test-listening an orchestral piece yesterday (which is the very loudest material I like listening to), and set the volume to a place where I was already fairly uncomfortable with the loudness, and after an hour of playback, only hit a peak of 92dB (with an average of about 72dB), which translates to 11-26 watts depending on impedance.

At this rate, B200s would be $600 worth of overkill for my setup.

92.3 dB was also my peak at „Jazz at the pawnshop“!
With my short listening distance and my 82 dB Speakers I would need just about 32 Watts -even with 6 dB extra headroom added (so that it would reach 99.2 dB).
But some people need more power just because a larger roon headroom is needed for doing some larger equalisation!
My amps are on 24/7 (not standby but just- on). Which is the difference between Topping B200 and Topping B100 in that User Szenario related to power consumption and the electricity bill?
 
After years of just using headphones, I finally got an amp and pulled my old PSBs out of the closet. After years of not playing music loud and knowing everyone else in my family dislikes my music, I start getting self conscious at around 65dB. I think I could power my speakers with a hamster and a wheel.

By knowing the situation very well, I can tell you:
The current is too uneven! I strongly recommend storing the energy temporarily. This helps the sound! (LMAO)
 
… and knowing everyone else in my family dislikes my music,…
Ah you don’t need that kind of negativity in your life, pal.

This applies to you specifically. It may not hold true for others in different rooms, with different speakers, or varying musical preferences, including those using EQ and room correction. There are examples and arguments supporting more power on page 27 of this thread.

Of course, but my point is that I’m sure there are FAR more people who think they need more power than they really do than people who have less power than they really need.

I have a different perspective. I believe many people would be surprised by just how much power is actually required for dynamics out of near-field.
 
Laziness. The Fosi V3 is under our bed (as the WiiM Pro Plus)

And the auto-standby does not work for you?

-Ed
OK, I can choose auto-standby for the WiiM but I think, the Fosi V3 (not the Monos!) has no 12 Volt Connection for transfer standby Information from WiiM to Fosi V3. Or am I wrong?
Hopefully it is just something between 3 and 9 Watts or so what the Fosi uses.

Okay, this was my failure to correctly comprehend. I thought you had V3 Monos, which have auto-standby (a feature the stereo V3 lacks).

Good morning great Chinese engineers,
First of all thank you so much for bringing high end audio DAC democratic cost to worldwide. Is clear you are the leader.
I have a E50 DAC powered with external linear PSU and can't be happier. Waiting another design with external DC input and latest state of the art thd figures to buy you a second DAC.
Your power amps are in distorsión noise the best measuring in the world but only missing someone long term stable to 3Ω speaker load like our loved big floor stander speakers of brands you can imagine.
The day you bring a power amp with the thd of b200/b100 but not only 120SINAD but also "long term 3 ohm stable" , you Topping engineers will simply wipe westerner class D circuit rivals from finished power amp market.
Topping today is great but future could be even brighter just with lower output impedance .
Thanks you again for your leadership DACs

Good morning!
@transformer-coupled is right! Thanks for your great devices. Can’t wait to hear the D900 DAC when it is aviable.
The next logical step for your company is maybe to go real high end and trying after the B100 and the B200 the construction of a B450 „Monster Amp“ with the same extremely low distortions as the B200. And that should work with every Speaker -even 2 Ohms! 450 Watts at 8 Ohms / 675 Watts at 4 Ohms / 1.300 Watt at 2 Ohms - all with less than 0.001 % distortion and with extrem large passive cooling for longer reliability - and perhaps a 5-year warranty.
That would be a High End Killer Amp with significantly smaller quantities than B100 / B200 but with much higher margins!
For me, a B100 is perhaps already powerful enough. But I know at least 3 high-end freaks who would pay up to $ 6,000 for such a powerful amplifier with perfect 2 Ohms stability and such power rating.
It would also be the biggest fear of all the companies who charge $ 30.000,— to $ 100.000,— for their not so well measured stuff……

Ah, and I asked Amir if he has the B200 in the pipeline…. but sadly, you have not send him one. So it would be nice, if you could send one to @amirm for testing!

Yours,

thorsten (still not shure if buying a B100 or B200 in November)

Have you got good fire insurance??
