So did you try their "private" version and did you pass it as well? Can you ask them if there's some way we (Head-Fi:ers) can get access to their private version? Thanks!
At their lab, we just tried a couple questions from it, and maybe my perception of it as maybe more hardcore was due to the fact that it wasn't as neatly packaged as this public version. Come to think of it, the ones we sampled were rather a lot like the public version's MP3 artifacts learning and testing, and the Gold Level timbre test (the second part of it).
I just re-read an email from Philips' Rowan Williams introducing me to the public version, and here's something he said about it (emphasis by me):
...The higher levels will test experienced listeners and contain the same principal elements as our own internal program. No doubt you’ll breeze through the early levels (you can skip basic and go straight to bronze), but I think when you get to the silver and gold levels you’ll find some challenging tests that I hope you’ll enjoy playing with...
Again, perhaps my perception is due mostly to how polished the presentation of this public version is.
By the way, the first time I went through it was without creating a profile, so I decided to do it a second time with a login profile (so that I could save the results).
The second time I went through it I changed headphones from the Sennheiser HD 800 to the Audeze LCD-X to see if it would alter the experience at all--it turns out that (for me) neither presented any overall advantage over the other. Over time, I'm going to play around with some of these Golden Ears tests with other amps and DACs and other headphones (over-ear and in-ear), just out of curiosity.
Anyway, for those who haven't taken it, do give it a go. In addition to being a nice learning experience and challenge, it's also fun.
