They have some jazz tunes, but only one classical as far as I can tell. So there is some acoustic in the mix. But too much heavy metal for my tastes for a speaker trial.
I couldn't do a test with those songs. AC/DC and Metallica? How on earth can you judge speakers using that music? While I'm not a big fan of using single woman songs either, at least some mellow songs can help. When I was testing DACs, I used Johnny Cash, as it was relatively easy to hear how his voice changed with each switch between DACs. Now, if you want to have some variety of music because you want to have the best "rock" speaker and the best "acoustic" speaker, that's a possibility, but they didn't seem to do that.
And equalization for speakers is quite dangerous. It can kill a good speaker, and often a speaker sounds better without equalization, especially for 2 channel.
