The World's First Power Amplifier with SINAD over 120!!!

[antcollinet]

In Australia we are supposed to have 230V - but my home has been on 242V (with minor variations) for years.... and occasional peaks of up to 252V (!)

252 is still within the 10% tolerance

Yeah - but not great for a lot of electronic gear... if the power supplies aren't fully regulated - everything is running hot....

On the other hand, well design amp power supplies, can use the extra juice to give you more oomph.

It won't be long now (10 years?) before every home will be running on its own Solar+Batteries setup, at which stage, your inverter will determine your voltage, and these concerns will disappear....

What's up with the extra long tease at L7AudioLab? Is this how they do it there?

... and now the wind has fallen. At least fallen off the front page of https://www.l7audiolab.com/
edit: @JSmith you are right. In my impatience I missed that it is still listed on the right, and only fallen off the "latest release" list. So my crack falls flat. Let's amend my crack to "falling fast". I'm not going to bump this thread though.

It's still there as far as I can see?

... no updates yet though, so maybe a bit preliminary.

Australia was 240V before 2000 and WA and QLD yet to transition. AS3112

In VIC we were purportedly on 230V quite a few years ago.... - but for a long time, Voltage at my home was 252V (pegged right on the max permissible voltage!)

Agree...

Yeah, all they did was change the nominal voltage and it's limits so there was no actual infrastructure change, AFAIK. Below is the national permitted variation from nominal I dug up, so yep they can operate at 253V for as long as they like.

@WolfX-700 so is this a April Fools prank or something real that is coming, or a mix of the two? There seems to be some confusion based on the Feb announcement on your site and the one from today that says it's a joke.

PA9 or PA90?

 

[Bleib]

Looks expensive (and I just bought PA5, will I regret the purchase?)
I'm sure Amir will get his hands on it, looking forward to reading a review

 

[freemansteve]

Why stop at -120dB? Why not go for -150dB and a cryogenic tank?

It's all about what you get for the money for me....

I'm sure it will be a great bench queen. Have reservations about toppings quality , there's nearly always problems. Will this be the first foray into custom discreet design rather than optimised chip circuits.

Well, now that looks interesting.

I wonder if that is Class AB or D. Only just over two weeks to wait to find out.

AB.

 

[antcollinet]

AB.

Confirmed...

So probably not for me, but we'll see how it works out.
