Did even even better. I just called Macintosh. See the reply above. My reply wasn’t harsh. It was wise ass just lik yours.

Also you should use common sense. Do you think someone is going to put out an amp that puts out a half of a watt?

Well this is what they printed in their full product details, under technical specifications, linked just a couple posts ago. Perhaps they should update that, also chill...I was making a silly joke about people thinking half a watt isn't loud. I'm not trying to get into an argument, this will be my last post on this.

Technical Specifications - Power Output
32 Ohm Load 500mW
100 Ohm Load 500mW
250 Ohm Load 500mW
600 Ohm Load 500mW

Nelson Pass likes the first watt! 😁
So I guess he would like the MacIntosh half as much. (You saw what I did there 😉)

I agree with you on that. To me it made no logical sense and that’s why I called Macintosh.

Looks like your farts and your brain are in the same place. Learn how to read and understand numbers. 500 mW into 1000 ohms. Go figure out how many watts it is into 47 ohms.
LMAO. Ya'll cray.

Love it.

I also spoke to Macintosh via email

genefruit= Hello, I'm excited to hear about the new MHA200 headphone amplifier. It appears to be a beautiful amplifier and I'd like to learn more about it. Specifically, when the specs note the same 500mW output regardless of load. Is this correct? I've read some conflicting information that says the following chart from your website is not correct. Can you address?
Headphone Power Output 500mW
Headphone Output Impedance
32-100 Ohms
100-250 Ohms
250-600 Ohms
600-1,000 Ohms

McIntosh = " Yes, the specifications as listed are correct in that 500MW will be the minimum available for all the impedances listed. "

McIntosh (emphasis mine) = " With an unlimited power supply, math says 500mW at 1,000 Ohms would be about 8 Watts into 50 Ohms, probably does not have that much power supply. Also, 8 watts would light most headphones on fire. "

genefruit = "I agree and is one of the reasons I'm reaching out is to get an accurate understanding of what the amplifier's output with a 47ohm load 88db headphone (Abyss) - https://abyss-headphones.com/pages/abyss-ab-1266-phi-reference-headphone"

McIntosh = " After we start shipping these you should take your phones to a dealer for a test listen. Then you will know. "

Alright then, keep you secrets...

That sounds like a concern to me in that they may not have tested the more difficult to drive headphones. Certainly not the answer I would have expected from Macintosh.

That’s really weird. The guy that you emailed must be the same guy that I spoke to on the phone because he use the same terminology of “light your headphones on fire “

They have to know what the heck their amp puts out based on their power supply.

If you guys are speaking with Ron, you'll find he's quite ambivalent which is a curiosity.
