Strangely enough, I am more tired of those class-D comments than I am of music listening on class-D amplifiers... (And yes, I also own non class D ones)Enormous listening fatigue

What is the unit of that crest factor?
Exactly what I mention when people complain about the price of Genelec speakers.First time to hear “greenflation”. What a manipulative neologism!
Not saying you’re being manipulative.
Let’s face it, if you are manufacturing in a high wage country, taking care for the environment (e. g. like Genelec) and not using slaves as work force you have to ask for a higher price. That’s totally justifiable in my opinion.
Not to go off topic, but since it's mentioned: manufacturing costs go BEYOND labor - it includes sustainability (which includes end of life strategy), material waste disposal, responsible energy/water usage, reasonable work hours (high paying 60 hour work weeks are not healthy), etc. ALL OF THIS, requires government enforcement because it massively raises the cost of a product without raising its performance or market appeal.Nobody will use work forced labour in this industry. You need at least 10 year of education to do assembly. You must be comfortable with machine and tools. That was decades ago. You can't do it with forced labour at all. With lots of automation, you need people at least 12 years of education to do it. Lot of programming and less hand on. It really against fact and science to claim forced labour nowadays, unless you talk about slave trade in Africa which don't involved in any technical field.
To add, it is not expensive to make this hi end gear in EU. Properly better than US as over inflated economy. In youtube, you can look see all the machine doing most of the work with a dozen workers. Even made in China is not affordable if you do not pushed for great quantity.
They went to great lengths to cool this amp with quality fans and heat sink design - the number one reason for electronic failure is excessive heat over time. You're paying for a product that is overbuilt for sustained high output tolerances. If you're only going 60 MPH, no reason to overpay for Pirelli P Zero tires for sure. But if you're driving low sensitivity speakers for loud dynamics representing a symphony orchestra from over 2 meters away in a well damped large spacious room?I don't see a reasonable value equation in the Vera Audio P400/1000 amp. From the measurements it looks like the Purifi design offers similar performance for almost 1/3 the cost. The hand written 120 VAC on the back seems to indicate it's not really designed for USA distribution? And as far as a switch for gain it's just another part that can fail. The XLR inputs are mounted too close together for my taste. I'll skip this one for the upcoming Buckeye Purifi model.
Let's remember that all Hypex amplifier modules are rated for short-term use. Continued use causes power throttling. So beyond reliability, getting full power long term requires proper cooling. Unfortunately the modules are not made to be easily cooled so it does take the effort such as the one here to get there.
Give it a proper heatsink with fins and low K/W coefficient and you are there. Of course the smaller boxes made from sheet metal do not make it, a fan is not enough. But the current demand are smallest boxes with many channels, so then it is what it is.Let's remember that all Hypex amplifier modules are rated for short-term use.

Oh yeah, I can certainly see plenty of valid uses cases, just not any I am likely to personally encounter in the foreseeable future.Thank you Walter.
We do actually have several customers who have bought one and found out they reached the clipping limit and ended up buying a second one.
The need for power varies greatly and depends on speaker sensitivity, listening distance, how loud one is playing, and whether one is using something like Dirac that steals a good amount of level.
Nobody will, only test signals can ask for an amp to push full power continuously, not music or video medium content. And that's if you don't blow your speakers or your eardrum before the throttling occurs.I have not seen any evidence of power throttling with my everyday use.
I looked, read, looked again, I was about to give up that, shame, there is nothing I can criticize, the horror!
Then I found it!
I don't like a major set-up setting like stereo/bridged to be treated the same as operational settings like gain and that they are placed next to each other. You use the bridge switch once the amplifier is connected but you adjust the gain controls later on. It is entirely possible to change the amplifier mode by mistake if you are trying to adjust the level controls standing in front of the amplifier but reaching the knobs at the back.

It would have been perfect if the bridge switch would be made different and difficult to be used by mistake. A slider switch with a recessed tag is the best for such settings. Example below.

Needless to say. I am nit picking. I voted Great. However, excellence is not easy to achieve.
May you explain how Dirac can "steal" level? That would come upstream of the amp no?Thank you Walter.

Imagine Dirac increases some part of the frequency range by 5dB digitally. You now need -5dB of digital preamplification as well, to avoid signals potentially going over 0dBFS and clipping. If you then want the speaker to play at the same level as before, the amplifier now has to make up for the "lost" 5dB in the digital domain.May you explain how Dirac can "steal" level?

Simple, and rather intuitive.
