Hi friends,

longtime happy lurker and learner, now registered and my first post: I assume I would not hear a difference between the B200 Monos and the fantastic Fosi V3 (original stereo). I have a V3 P3 combo that drives the Wharfdale Linton without an issue. A wonderful combination. Sine both the Fosi V3 and the B200 are transparent, I guess, I'm more than good with what I have. (Listening to gentle levels, not loud.) Or, to use the aforementioned picture, I would only buy a fancier car to stay in city traffic.

Greetings :)
 
I got creative :p

Topping B200: A Measurable Marvel, But Where’s the Soul?

Introduction
Topping has gained a strong following in the world of high-fidelity audio, particularly among those who prioritize measurements and technical performance over subjective musicality. With the B200 monoblock amplifier, the brand continues its pursuit of textbook-perfect audio reproduction. But does it truly engage the listener, or does it simply check all the right boxes in a lab test? We set out to discover whether the B200 delivers more than just numbers.

Design and Build
As expected from Topping, the B200’s design is functional, if uninspiring. The matte black chassis is solidly constructed, but lacks the tactile charm of classic audiophile designs. There's a stark absence of visual flair—no VU meters, no distinctive accents, just a minimalist front panel with a single input select button and three small LEDs.

At just 8.2 inches wide and 2.5 inches tall, the B200 is compact enough to fit in a desktop or tight shelving, but this form factor also raises questions: Can an amplifier this small truly deliver the deep, organic presence of a high-end power amp?

Features and Connectivity
Topping continues its trend of emphasizing specification-driven design, opting for a Class D topology—a choice that maximizes efficiency and measurable performance but often divides audiophiles on sound character.

The rear panel is straightforward, featuring:
- Balanced XLR
- RCA
- Trigger input for automated power control

Speaker connections are handled via gold-plated binding posts, which feel adequately sturdy, though they lack the substantial heft of those found on premium amplifiers from brands like Pass Labs or Luxman.

Performance
On paper, the B200’s numbers are nothing short of stellar. Topping claims 250W into 4 ohms and 135W into 8 ohms, with distortion levels as low as 0.00008% (THD+N, 5W @ 4Ω, 1kHz). These figures rival some of the best measurement-based amplifiers on the market. But as we know, music is more than just numbers.

Sound Quality
This is where opinions will diverge.

- Bass: Impressively tight and controlled, but lacking the warmth and physicality of a well-designed Class A or AB amplifier. The B200 delivers bass with precision but not with emotion.
- Midrange: Neutral to a fault. While vocals and acoustic instruments come through with clarity, there’s an analytical quality to the sound that keeps it from feeling truly immersive. The emotional weight of a singer’s voice or the resonance of a grand piano feels slightly detached.
- Treble: Exceptionally clean and extended, but bordering on clinical. The amplifier does not add any noticeable coloration, but it also does not enhance the listening experience in a way that some might expect from a high-end component.

Pairing and System Matching
Given its ultra-low distortion and high power output, the B200 is a natural match for those who prefer a highly resolving system. However, listeners who appreciate warmth, texture, and harmonic richness may find it lacking. Pairing it with inherently warm speakers, such as Harbeth or Sonus Faber models, helps offset its sterility, but even then, it never fully escapes its analytical nature.

The Verdict
The Topping B200 is, without question, a triumph of engineering. It delivers pristine, distortion-free sound with extraordinary precision, making it an ideal choice for measurement purists and detail-obsessed listeners. However, those who seek musicality, organic textures, and emotional engagement may find it lacking. The amplifier’s flawless technical execution comes at the cost of soul and character, making it a device that some will adore and others will find uninvolving.

Pros:
✔ Incredibly low distortion and noise
✔ Compact and efficient design
✔ Excellent power output for size
✔ Transparent, highly resolving sound

Cons:
✖ Somewhat sterile and analytical
✖ Lacks the warmth and texture of classic audiophile amplifiers
✖ No VU meters or aesthetic appeal

Final Rating: ⭐⭐⭐⭐ (4/5)
For those who prioritize technical perfection over subjective musicality, the B200 is an undeniable achievement. But for those who believe music is about emotion as much as precision, this amplifier may leave something to be desired.

As always, the best judge is your own ears.
Soul? Is the job of amplification to reveal the unadulterated musical signal recorded, or shall we again look for colored glasses to enjoy Monet and Michelangelo better? Does soul mean character? Does the alteration of a known Musical offering capture our attention because it sounds different?

I go with the most revealing chain possible, i.e. the lowest possible distortion and noise. While your writing is enticing, it is ultimately an unconvincing opinion.
 
From my perspective, amplifier must be transparent, analytical/flat & boring, yes? Any colourful excitement means corruption of original signal, no?
 
Topping can only win by issuing an international guarantee regardless of the place of purchase.

That's only your opinion though, I weighed up the advantages and pitfalls, ordered from China.

Now which stays the Toppings or the Benchmark AHB 2 ??.

The Benchmark is over three times the price but more easily serviceable.
 
With those depth I don't think they count as heatsink

The fins are 30mm deep, the fins on the AHB 2 are 38mm.

My B200 run barely warmer than room temp , though my speakers are not current hungry.

It was only meant as a joke by @digitalfrost! He is one of ours - the good guys!
You have to read the posts bevor his post. ;)
 
@amirm: In case you will make a rerun: Temperature measurements would be nice!
this amplifier and power supply are somehow cheated in terms of temperature. After many hours of playing at medium volume on floor-standing Lumina V speakers, I was not able to heat it up even to 29 degrees Celsius. the temperature at home is about 21-22.5 degrees. B200 is still normal to the touch, you can feel the cool aluminum. I put the thermometer on the top of the case and on the side by the radiators. The power supply does not produce heat either. you can even close these devices in a ventilated cabinet measuring 40x40x40cm. For example, M6si in the same conditions reaches a temperature of 36-38 degrees Celsius.
 
This is a review and detailed measurements of the Topping B200 "monoblock" (single channel) audio amplifier. It was sent to me by the company and costs US $599.

I don't think it is possible to make the unit more solid and high-quality feeling in this form factor. The amp is heavy for its size (although you can still easily pick it up). The single push button power the unit on/off and selects one of three combo balanced XLR/TRS inputs:

I like the spaced out speaker terminals and high contrast labeling. Topping has made trigger automation standard on their products which is much appreciated.

Two gain settings are provided unlike the three on B100.

Topping B200 Amplifier Measurements
Let's start with low gain testing into 4 ohm load:
View attachment 432844
I must say, as much as Topping always produces state of the art products, I am always pleasantly surprised the moment on turn on the analyzer and see such superlative results! Distortion is vanishingly small at -140 dB so our SINAD is dominated by noise. It lands the B200 at top of the graph, edging out the B100 by a faction of dB:
View attachment 432845
View attachment 432846

There is still of course some penalty in using the higher gain, but still excellent results:
View attachment 432847

As much as noise sets SINAD, it is still state of the art, especially in low gain:
View attachment 432848
View attachment 432849

Being a conventional design, frequency response has no load dependency and shows wide bandwidth:
View attachment 432850

Multitone and 19+20 kHz intermodulation distortion tests show very little rise in distortion with frequency:

View attachment 432852

Topping amplifiers until now have had average levels of power. That is changed with B200 landing in "high power" category now while still maintaining its superb noise and distortion:

View attachment 432854

By now, the amp was fairly warm and it seemed that it was pulling back a bit in available power:
View attachment 432855
The above test pushes the amplifier into clipping repeatedly to find the 1% point and it seemed to rob the amplifier of some power. Later reactive tests with the amplifier being cooler showed the full power rating coming back.

Here is our new 40 Hz power rating while the unit was warm:
View attachment 432856

And "FTC like" full bandwidth power which lasted about a minute while again repeatedly pushing the amplifier beyond clipping to achieve 1% THD:
View attachment 432857

The "transfer function" is extremely clean, showing just a slight degradation with frequency as noted earlier:
View attachment 432858

No class D is able to achieve this level of performance at this time (although they can be a lot more powerful).

I had dinner and then ran the reactive load tests:
View attachment 432859
View attachment 432860
I was pleased to see it produce power even at 2 ohm although past 0 degrees, the protection circuit was interfering with the measurements so I show that as zero. Max power is available at 4 ohm. But healthy power is available at 8 ohm as well.

Speaking of protection circuit, it was the kind I like where it a) allows the amplifier to go into clipping and b) self recover without shutting down. This made it possible to run the above tests with ease.

The amplifier is exceptionally quiet coming out of, and going into standby mode:

And the unit is stable on power up:

Conclusions
One or more designers at Topping have figured out how to nail noise and distortion in any products they design. No matter how difficult it is to "port" that to other product categories such as this higher power amplifier, they deliver on that. As such, Topping owns the category when it comes to medium to medium high power amplification when it comes to performance. Try as I might, I cannot find any faults here. The product itself is also attractive, feels high quality and has proper features, sans a VU meter.

It is my pleasure to recommend the Topping B200 amplifier.

I've had mine for a little over 2 months now. The sound is so pure, but of course that is subjective. Any problems have been with integrating it with my AVR and Eversolo A8 (also purchased at the same time). My only disappointment in the review/product has to do with my expectations. I was expecting the power output to mirror that of the Topping L90 discreet in mono mode--the B200 is significantly lower, especially in burst.

The amplifier not reaching double the power when the load impedance is halved is a sign that it hits a current limit before reaching its voltage limit.
Ideally, an amplifier should double its power when impedance is halved, proving it can handle high currents effectively.
Ideally? You mean insufficient output voltage?

I would like to see an amplifier deliver its full voltage even into a 2-ohm load, at least for short periods, without hitting a current limit.

Only short periods = Weak power supply or weak cooling compared to output transistor with too much max output current

It is just design goal optimization. You start with a 1W into 4ohm amp, for double the cost you can either get 2W into 2ohm by doubling the current or 2W into 8ohm by doubling the voltage.
 
Amir!
It's time for us to get serious about thing.
I've already seen it in the USB reclocker video...
What are you doping that red orchid in the background with so many flowers on it?
Or is that a silk flower that blooms all the time?:):D
Very beautiful in any case.
 
Ideally? You mean insufficient output voltage?
Since speakers are voltage-driven, insufficient output voltage simply indicates the limit of the amplifier’s gain.

On the other hand, this means there is no change in tone or output depending on the load.

However, since a speaker is not a purely resistive load, an amplifier operating in the current-limited regime can change its output characteristics depending on the load. This is not ideal, as it leads to load-dependent output and is not linear

I don't believe what I'm reading, but what? Dust flows off better?
It's actually a thing in thermal design:
1741102112499.png


For natural convection, the difference can be large.

So yeah, if the heat sinks are part of the thermal design, they should be vertical unless force-air cooled.

It may be that this amp's heat sinks are cosmetic and they play little or no role in thermals. Electronics with critical cooling needs tend to orient the heat sinks properly (or fail early). I have at least one amp that would not be happy with high power operation without the heat sink oriented properly.
 
I'm hard pressed to recall an amp that performs much better regardless of $. Off hand, I assume the Benchmark product is still the reference amp?
 
I have been so happy with my pair of B200's I ordered a 3rd B200 for my center channel. We were watching Wicked with my daughter. At times I was struggling to make out lyrics in the songs. Vocals sound so good listening to music in 2 channel (F228BE) I thought the center could do better (C426BE) Currently it is powered by a buckeye amp with processing being handled by an AVM70. I will update once I have the new B200 installed and have rerun ARC. Most of the time it sounds great but in the first song I was having issues making out the words.
 
Capacitors are still weakest link in the circuit regarding longevity so nothing to do with audiophiles and such. No matter how much you might dislike external power brick it's practically to replace when it dies. All together very nice from Topping.
I was thinking same. The number of people saying the external PS is a "deal breaker" for them is illogical to me. It's a neutral thing, if not a plus, for me.
