And yet again Bruno strikes, with yet another D module, this time it almost doubles down to 2ohms!!!!!!!!
Seems in this one he gets grunt (almost doubling) right down to 2ohms, not just shelving off at 4ohm and running out of steam any lower.
VTV are going to use them, this looks a bit messy though, maybe a prototype VTV Purifi High Power Module | VTV Amplifier

You know what, my bad. I see the youtube spammer (for that video and youtube channel) appears to be from the US. My apologies.
Wow. That escalated fast... 🙂
The main difference seems to be that the new modules use a 54-pin connector with many of the pins assigned to OUT+, OUT-, and the power supply. The 1ET400A uses a 36-pin connector.
I'm sure there are other differences too, but it looks like more of a design tweak of the 1ET400A rather than a complete redesign. Not saying that's a bad thing. Just making an observation.

Yes but what's good is that it increases wattage substantially from 4 down to 2ohm which is Class-D's Achilles heel

Only because they tuned them for parallel active sub use. Because that’s where 90% of the sales will be.
I don’t believe they are. Too many OEM’s complained about the 1ET400A being sold to the DIY market. So it ended up hurting overall sales.
Wow. DIYers are what....1% of the market? Ok, let's say 3%. If that 3% is hurting your business, you're in the wrong business lol.
It’s not about that, it’s about manufacturers not wanting to bother with them because of the perceived decrease in value based on the cost to DIY the amps. Those who understand industry standard profit margins might understand this.
It's hard to justify diy'ing a purifi 400 when you can buy a completed amp for less than the parts.
I was going to say the same, but in Tom's case, i'm sure he would only need the amp boards, not the PSU. Its not cheaper that way, unless the extra PSU was able to be onsold, or needed for something else.
Nah. Probably much less than that in terms of percentage of revenue.
DING! DING! DING!! DIY = cheap. That's the problem. It's hard to command top dollars when you're being perceived as cheap. So Purifi probably doesn't want to have the 1ET7040SA associated with DIY, so they don't sell to DIYers.

And yet they are OK with amp sellers selling a complete amp for less than the cost of the parts? indeed, it must be about perception.
