Please elaborate in the [Crack](https://forum.headphones.com/t/bottlehead-crack-otl-amp-kit-diy-official-thread/1937) thread.

I personally never liked the 6XX on anything other than an OTL amp – OTL is transformative. Still, I use my Beyer DT-880 600 ohm and HD 800 S more than the 6XX on the Crack.
