Keep in mind I'm not talking about the regular Focus Pads, I'm talking about the Focus Pad As. They're similar, but not the same.
We're talking about 1-3 dB difference at 10-30 Hz, so yes, it does "come close". And like I said, I would never choose that over complete tonality - not to mention that many songs roll off or even do a hard cut at these frequencies. The Asgard 3 has more than enough power for the HE-500, and you responding in a semi-rude manner (suggesting my equipment or my ears aren't good enough) isn't going to change my opinion on my pad choices.
Edit: This is the kind of difference we're dealing with here. I couldn't find any of my more recent measurements, but I have the regular focus pads vs. the vegans - the latter of which has a flat response just like the Ethers.
Blue is stock, yellow is the regular focus pads, purple is the vegans:
1-3 dB difference at 10-30 Hz. If that's what you want to place the emphasis on when choosing a pad, then by all means do so. I personally don't.
