Hey Mofojo,
My own taste in music revolves around jazz from the late forties until the early seventies (Blue Note, Impluse, Prestige, West coast labels). However, for reviewing proposes I used many hard funk, and rock records to evaluate the DI's performance regarding dynamics/punch and they handled with ease anything I throw at them. The DI did not make rotten recorded music sound great, however it still drew out the best of what could be done with these recordings.

I believe that Linear Tube Audio is also one of the greatest bargains in high-end audio along with the DI speakers. David Berning is another genius and how Mark has brought his design to the market for regular folks who could not afford Berning's much more expensive line is a blessing for music lovers (Just like Eric's DI speakers) . Believe me, based on a lot of listening experience the ZOTL pair is as good as anything out there. Think of the color/timbres of a 300B amplifier with the balls, speed, and kick of a 845 tube! And for tube gear its dead quite.
