Dry isn't the word, but since the 160 is a no-nonsense amp and the T1 can easily be harsh and metallic, the burson makes the T1 very very harsh indeed.

I did try the T1s with a DNA Sonett and they were pretty much on par with the worlds top dynamic headphones with that combo.

The difference and synergy of amps sometimes can be a hair's breadth apart, and sometimes its due to psycho-acoustics, or even individual emotions.
