What its output into 6 ohms compared to the 40 wpc into the rated power into the standard 8 ohm load? Approximately
VU meters
have recently been sprouting on a lot of amps. However I can’t think of any usefulness and imo it’s just “window dressing”. Fine if you like it and seems many do
I really want an A40 but believe it or not that’s something that’s been holding me back. I like functional aesthetics.
Minimalism will always have a have a following. Any chance of doing a batch eg 50/ 100/ 200 without them. (And o course with a faceplate without two round holes) though you’d have a small saving on parts & fitting it’d be a special run. So if it were to cost a little more I’d be prepared to pay that extra

The VU meter is part of the aesthetics and visual design but mainly it shows that the amp is working (responding to input) and that one is not driving it to excessive clipping levels.
It sounds easy to say, let’s make a front plate without the VU meters. But it’s a different production batch and changes to a production line are not easy. I’ll look into this prospect.

What is stopping you from building one without vu meters?
Modushop has nice cases with thick aluminium front, great looking. No need to drill holes for vu meters.
X has boards, all parts are available, lots of support, plus this is diy site after all.
Yes, but. I’d hope we would not have doubts about it functioning.
Clipping … of the number of people who use amplifies, how many have clipped them?
Let alone amongst the kind of person who would buy a class A amplifier(!)
Yes, I’d said it would be need to be a batch. Though I wouldn’t think that within the overall manufacturing process changing (?) less than five parts for a run of eg 50 - a couple of days? a week? of production would not be difficult for a reasonable manufacturer(!)
Much appreciated
I like the aesthetics and acknowledge that careful thought has been put in, and several nice choices made.
All apart from what I think is a gimmick, and a rather obvious one
I had VU meters on the cassette decks I used to have. Used them every time I recorded.
But in an amplifier … just for listening, no thank you
If you don't like the amp, then you don't have to buy it. As @adason wrote, you can build this amp to your liking (it's a DIY forum after all) or you can leave it alone. Criticizing a manufacturer because it doesn't suit your taste is not the polite thing to do - as we all know, tastes are different and you can't discuss it.
You totally misunderstand me.
Is that meant to be informative? 🙄
You’ve now stated the obvious four times
That is your serious misunderstanding. It seems you either did not read what I wrote with any care, eg -
“I like the aesthetics, and acknowledge that careful thought has been put in; and several nice choices made.
My original post
“I really want an A40 …
And or can’t tell the difference between asking for a cosmetic simplification of a product and criticising the project lead
the usual things. Time, already a lot of projects I might never get to
Yes, am aware
Yes, but this particular thread is about this product: a commercial spin-off.
By a diy-commercial audio polymath who from his many projects and many posts I feel I’ve almost come to know him
which will be produced locally (California) in much lower volumes than mass market
I wouldn’t suggest a change to the front of a Sony or a Sonos
You do not know XRK971, very few do in fact, and it is being built in China and finished in mainland US (not CA) and marketed from TX.
You are limited in your knowledge of the commercial product for obvious reasons, but if you are prepared to DIY the AN39 all the meticulous information is there for very little effort and at zero cost. But you are far too busy for that!

perhaps? I overstated. I said I feel I’ve almost come to know him …
in the context of his many diy projects and commercial projects with VerFi and LSA.
my memory is incorrect. Though the company‘s path from components to sales isn’t relevant it does conv you know much more about it than me. As we would expect! You being the designer of its unique core circuit. For which you are due even more respect than you already have
I don’t know why you repeat the DIY option. And “far too busy for that!” implying … I’m not sure what.
But as you do, fyi my collection of diy projects - audio, other diy, house renovation is literally insane.
at the rate I’m able to progress them, to be frank due to psychological problems and limited technical knowledge - I wouldn’t be able to get through them if I lived to be 500.
By not taking on one of the - no doubt brilliant Nirvanas (I was seriously considering doing a big boy) I am avoiding adding to my insanity
Peace, and Respect
I would not suggest a Big Boy; a better idea would be to build the AN and then build it out with 36V rails.
This is a significant project, even though there are only 6 semis. The fact is the thermal issues are difficult to achieve and the best implementations use passive heatsinks, which are VERY large as you need more than 0.15C/watt for the entire channel, so best built in monobloc.

it's funny the things that make amps easy to live with. For me, it's having the power button on the front. that's huge. my back isn't getting any younger. also this way I don't have to slide my forearm on top of a burning hot class A amp to blindly search for a power switch. I've noticed all xrks amps have a front power button! the warp 1, the emerald physics ep600.2se and the A40.
I recently acquired a really great sounding class A amp but only having a power iec rocker on the back is a big inconvenience in my particular racks/shelf situations. So I'm back on board the A40 train! Chooo chooo! I put my deposit down today =) Not sure why the release slipped to August but that's tons of time to build up my bank account and by then, I'll be bored of all my current amps! Let the A/B testing commence! (in august)

Hi Uncola,
Thanks for your support. We relocated the manufacturing of the A40 from China to USA (Southern California, North of Los Angeles - near the coast). The factory has been going through power shutdowns and evacuations over the past month due to the fires in Los Angeles. The fire has wreaked quite some havoc for this product and others manufactured and distributed from our LA location. This accounts for some of the delays but most are because we moved production from overseas back to USA. In the end, you will get a beautiful sounding and looking amp made here in the US. Given the new tariffs, our decision to move worked out well.
Just want to thank all of those who placed a pre-order for your patience.
Yes, I am a big fan of an illuminated power button on the front. You will notice the user interface on all my amps is very similar. There is still an IEC rocker switch on the back to kill the power completely when you don’t want to be in standby mode.
