What high source output impedance meets uneven load impedance sounds like

This has been sitting on my desktop for a while so I uploaded it before deleting it.

I did do this with an MS-1 last time, but MS-1's impedance is fairly flat so there isn't much to be heard. This one is more extreme.

A quick look at three laptop power adapters

So due to some circumstances, I have three laptop adapters, and a lapdesktop to power. Might as well see which is the most efficient.

Xonar DX output impedance

~86Ω @ ?V into 33Ω load
~108Ω @ 0.15V into 16Ω load

Update 23/03/12: I remeasured again with a 16Ω load @ -22.7dB into a 16Ω load and got 108Ω. I will try to remeasure when I get another 33Ω load working, but I'm expecting both figures to be correct. I'll post the possible explanation once I confirmed the numbers.

Well you don't have to read the rest of my blabbering, but if you want to,

Diminishing returns

"As with all audiophile products, diminishing return rule indeed..." - quoted from somewhere

But, there is another camp that believes the opposite - the higher you go, the more something affects.

How about the third camp -

It is possible to have both decreasing and increasing returns.

Because placebo effect doesn't care if you think the returns are increasing or decreasing - that is how you interpret the improvements... that don't exist.
