the quote from Alan Shaw
But let's be fair and responsible. Let's set aside all arguments about sound quality and power for a moment.
As I have said before, and strongly echoed by hifi_dave (a lifelong hifi retailer), you have to factor-in after care. An amp that is sold for 179 Euros cannot be built to last. Built to a price point, the procurement department are mandated to shave every cent of the bill of materials as the design engineers use every trick in the book to reduce component count. The attitude is, and this is how consumerism flourishes, 'when it fails chuck it away'.
You have to take a personal view on this. One replacement drive unit in the speaker damaged by a budget amplifier that fails dwarfs the cost of the amplifier. Is that a risk worth running? I'd say no.
Doubly so because to the trained eye, when there is an autopsy on the failed drive unit, the tell-tale signs of amplifier distress failure are unambiguous. So no Warranty cover.
He is saying an inexpensive amplifier is more likely to fail, a rather condescending and elitist opinion, and a scare tactic to get you to purchase abettermore expensive amplifier.
Incorrect.Anyway if I would buy the Benchmark nobody could say something.
its the best measured amp.
Incorrect.
An AHB2 can also fail or be overdriven, leading to the same signs on the drivers.

Any Speaker manufacturer can deny warranty service because the damage has nothing to do with their product, simple as that.
Personally, while I would love me some AHB2 as well, I believe you are overthinking the matter.
No this is not a problem at all. Capacitive or inductive speaker loads will not cause stability issues. The feed-forward system is inherently stable. The only limitation is the over-current protection circuit. The amplifier will shut down if repetitive peak currents exceed 29 Amps or if the RMS current exceeds 20.5 Amps for more than a few seconds.
The TEMP lights will flash when peak currents exceed 29 Amps. This is a warning that the protection will kick in if the condition persists. The CLIP lights will flash whenever the amplifier is driven into voltage clipping causing the THD to exceed about 0.5%. If the CLIP and TEMP lights flash together, it indicates that you have simultaneously reached the voltage and current limits of the AHB2. Each channel has its own set of lights and has its own protection monitoring. If protection is triggered, both channel will mute. To protect your tweeters, the distortion monitoring will not allow sustained operation if the amplifier is driven into voltage clipping resulting in a sustained THD exceeding 1%.
btw I just checked a couple of pics of the Behringer A800 pcb and first thing I noticed are the crappy Capxcon capacitors (good luck with them), also I don't think the pots are Alps etc.

it may have not the best capacitors but you have to remember it’s made to a price point. it will still work with your speakers and probably for many more years.so basically you re saying it’s crap and it’s good for the bin?
i m not cynical English is not my native language.
how is it possible that this cheap, and shit parts amplifier have good measurements.
that say a lot about all the other amplifiers, who have worse measurements.
i m not technical educated, so I go by what people say on this forum

You’ll probably upgrade before it gets a chance to coming close to failing on you.
keep using it if it makes you happy.
Would they service under warranty if your kid kicked in the woofer?what you are saying is what ever amplifier you buy, the manufacturer of the speaker can always hide and say it’s the amplifier fault.
i like to believe an amplifier from a company as behringer crown etc etc Luxman whatever that those amplifiers must have a standard that will cause no harm to our speakers?!
Would they service under warranty if your kid kicked in the woofer?
No.
So why should they do so if a user uses an defective amp or mis-uses the amp (e.g. overdriving it)?
To them, there is no difference: some factor out of their control damaged the product -> not covered by the warranty.
The Behringer is aimed at professional applications and people. These people know what to do and what not to do, so there is no need for elaborate protective measures analogous to the AHB-2. We as home users often do not have the knowledge and experience needed.
Also, in a PA setting (delivering sound to crowds of people), people are generally not concerned with uber SINAD stats and audiophilia nonsense, they want power, reliable and cheap.
Get the AHB-2 if it makes you happy but don't worry so much about your Behringer. It will work just fine, just as millions of consumers drive their speakers just fine with AVRs budget amps, that most definitely do not use exotic and super impressive components.
It was not the 2x140 wat Artera that he used but a much less powerful Quad model. I use a refurbished Quad 606-2 in my system and have no complaints. It is a well respected design, and I would only consider something else if I needed more power. I might then go for the bridged Quad QMP or a Hypex amplifier for the lowest price for a really powerful amplifier that also measures very well. But I am happy now. The AHB2 is of course the ultimate amplifier, but I would like more power and I find the price of two in bridged mode a bit hard to justify compared to what else I might do with that money.He did try to use an Artera Integrated at a recent UK show but it's suspected he didn't set the gain correctly as he found it underpowered (too quiet?).
