I managed to make it to -18db for the first test. Not too bad I guess considering I'm using the motherboard for sound on this computer.
Thanks for sharing BTW.

I have a pair of Acoustic Research wireless headphones and using those the best I could do is -18db. These are plugged into my Yamaha HT receiver. The receiver is connected via SPDIF to my HTPC using on board HDA (high definition audio).
Now, my hearing isn't what it once was, but when I play this through my 3-way active speakers I can consistently get to -24 and on occasion -33db
The setup for that is the Yamaha's front pre-out connected to the active amp.

It would be nice if they had a few different songs and artists to add variety. I'm not a big fan of Tracy Chapman.

Yes, I'll be getting a decent pair of headphones soon. The AR's are krap - static and other noisey garbage, no bass and obviously low fidelity.

Some of the octave tests I can go to -36.

I think I'm learning how to listen for distortion.

What's most evident is that I can easily imagine kinds of distortion that actually sound GOOD.

I wonder how hard it is to pick out 2nd harmonic from 3rd on a similar test to this...

Your still using IE?

This looks an interesting test... i'll give it a try (but now now, the masking from the windstorm would make it difficult)
